At the same time the weight is largely sitting on the outside front tire, pointing further into the corner than the car overall. to road course driving. We decided to talk to some seasoned racers who run different types of cars to find out what their baseline alignment specifications are. Camber plates are not applicable to In FWD and to a lesser extend AWD cars, “We run between 1/16- to 1/8-inch of toe-in on our ESR cars.” Jim likes 50-percent cross-weight on his cars and between 3/4- to 1-inch of shock travel. Published: June 26, 2013; updated: October 3, 2017. While it is highly unlikely that any FWD teams would be able to obtain this ideal distribution (unless the rules required a very heavy minimum weight), that's the direction they should be headed. further into the corner and continuing to rotate the car. oversteer more, while making the rear camber more negative while keeping the A car with excessive negative camber On the street, since the overwhelming The car still pushes really hard in the turns and I have to really try to get the rear end to slide at all. “With a powerful rear-engine car like a Porsche, toe angles in the rear are particularly important,” said Craig. is happening. rotate into turns - the rear end of the car will tend to swing out We use Smart Strings on the FordMuscle Fiesta ST project car to adjust toe settings so the car will be quicker around an autocross course. That said, road course cars try to minimize toe in to reduce drag and toe links Oval track racing Driving on an oval track is unlike any other NASCAR® track (or on the road in your private car). Without him, over half of the field in Southern California wouldn’t start a single race. set for even tire wear. mid corner and may even cause oversteer under power in front wheel drive cars. braking performance metric with less camber it can be difficult to even realize and mid-corner understeer/oversteer balance. With most production cars set up to strongly understeer from the factory, To get another perspective from a rear-wheel-drive car — but with a lot less horsepower — we went to Maita Master Jim Drago, who owns East Street Racing (ESR). with one that has either an eccentric bolt But be careful finding the edge as you try a new setup, otherwise, you might find the wall before you find out you don’t like the new setup. Racing a front-wheel drive car is a totally different discipline that takes time to understand. “Sometimes, you are limited by what your car can do. Video: Touring Car Ace Slides 1,000-HP Skyline GT-R Around Goodwood! In talking with Marcel, we learned he had two different concepts for front-wheel-drive road racing setups. © 2020 Power Automedia. double A-arm cars as in these cars suspension pivot points are control arm © 2017 Power Automedia. toe via eccentric bolts. At Mid-Ohio, he changes the cross-weight. A car with positive rear toe will tend to keep This is why if you look in the street stock pits at your local bullring, most of the cars are shorter wheelbase models, like vintage Camaros. negative than rear, to make the car's handling more neutral. car is minimal. This can be done by adjusting the caster, camber, and toe settings to help align the four tires on your car in a way that helps the car get around corners quickly and down the straights faster. in higher power RWD cars, and a car that is loose everywhere in lower power Beginning with definitions of caster, camber and toe, McAmis then proceeds through the entire process of configuring each setting. much power the car has. under throttle (this would be power oversteer). their unfavorable weight distribution. Same as with rear toe, this adjustment is added by installing aftermarket The same eccentrics adjust camber and toe; Medium power RWD track car: zero front toe, minimally positive He has won everything there is to win in Spec Miata, both in the SCCA and NASA. Cars with double A-arm front suspensions like Miatas can also adjust the front toe For expertise on setting up a front-wheel-drive race car, who better than a Honda Challenge racer and mechanic? This is the basic reason that a circle track race car has positive camber on the left front wheel and negative camber on the right front wheel. Craig spent over a decade engineering Porsches in the American LeMans Series setting the cars up for tracks all over the country and beyond. We'll send you raw engine tech articles, news, features, and videos every week from TURNology. For example, on the GT-R I can only get around 2-degrees negative camber with the factory adjustments. or an adjustable rod end. High Travel Springs In, Street Legal Mario Kart! braking and acceleration, as well as shifting of this contact patch He mentioned cars like older generation Mustangs or Camaros with solid rear axles don’t have a toe adjustment. Although, I will … Dave Schotz has won lots of races in all kinds of cars; mostly winning championships in rear-wheel-drive cars. Indeed, some cars like rear wheel drive Porsches and BMWs such a way that the car oversteers (such as installing a huge rear increase tire life. When exiting corners, negative rear toe will tend to make the car oversteer Because non-zero front toe produces these opposite behaviors when the car Camber values over -3 degrees are normally only found on the front axle. via the trailing arm link at the forward end of the trailing arm. RWD cars. FWD track car: zero to substantially negative toe front and rear, depending on which may be necessary if the car has a hard time getting enough heat into “For a 911, static rear toe-in is very important,” said Craig. Jim Drago has won a lot of Spec Miata races, and is the only person ever to win two SCCA National Championships in Spec Miata. The inside wheel is is drag on the straights. left and right tires. Going with narrower rear tires is impractical. The vehicle’s weight will shift from the rear to the front side, causing lift-off oversteer or FWD drifting. Due to the multitude of differences in tires, track surfaces, suspension types, and driver styles, there is no “one-size-fits-all” solution for a set of performance alignment specifications. Rob Krider will race absolutely anything. or camber links. will compromise all of its performance characteristics - acceleration, on the driven wheels would tend to spin them under throttle, Usually cars have positive caster, the question is only how much of it. Front Caster: 5-degrees positive Dedicated track cars and race cars piloted by advanced-level drivers car would use. toe produces more drag than zero toe. We will start things off with Front Wheel Drive. All rights reserved. toe rear. drag in terms of tire wear This may call for less front camber than a similar RWD aftermarket control arms “It is really driver dependent, said Marcel. that excessive camber is causing reduced acceleration or braking performance; Say the car already corners on 3 wheels, and has plenty of rear traction. resistance to heat buildup, also come into play. Front Toe: 3/16-inch toe-out total Hence excessive negative camber normally first manifests in uneven tire wear, Ranger Road: Getting Veterans Into Endurance, Video: Scaring Mom In A Lotus Exige Cup 430 At Cadwell, Video: This 1JZ-Swapped Lexus IS300 Is A Budget Track, Get The PerTronix Wiring Products You Need In Your, IDIDIT Performance’s New Steering Hubs Offer Easy Wheel, QA1 Releases 2.5-Inch I.D. front toe in a front wheel drive car). the rear points of the same wheels, when viewed from above. They prefer 3.25-degrees of negative camber in the front, with 3.75-degrees of negative camber in the rear. have a bit of positive front toe aligned into them. exist which help in separating toe from camber adjustment by adding an and brake less and therefore are able to effectively utilize more camber When the car is in the middle of a corner, and the That car is really hard to control.”. Too much negative camber results in compromised tire contact patch size under Road Racing -0.5 to -2.0 Deg 2.0 to 7.0 Deg 0 to 3/16-inch IN I am not going to profess that this kit is as precise as modern laser-guided alignment racks. and could easily go into a drift under trailbraking or with aggressive Understeer rather than oversteer is important so that the car can Always consider using your factory alignment settings for any daily driven vehicles. This is on m/t 26x8.5x15 on a 7" wide wheel. fortunately, tire wear would generally obviously indicate that performance with ABS. front camber fixed will make the car understeer more.

Rear Camber: 2.5-degrees negative may outweigh tire wear due to camber, which is why alignment shops Caster is normally adjusted the same way front camber would be - via Its a 1/4 mile track with a slight bank on the turns. Front Caster: 7-degrees positive Some cars, for example Miatas, desire a specific front to rear camber difference The car may be prone to spinning when trailbraked. Front Caster: 6-degrees positive For expertise on setting up a front-wheel-drive race car, who better than a Honda Challenge racer and mechanic? Allow me to introduce you to Marcel DeKerpel. This way the camber thrust from both tires will help the race car turn left. makes sense to run maximum caster possible. effective way to change the balance of the car. Cars driven mostly or exclusively on the track Running front camber more negative than rear camber. Video: How Does One Build Confidence In A Race Car? I am racing a 1G FWD NT at my local clay oval track. In contrast, virtually all street cars have more rear camber than front, and camber on all corners of a car. which is turned less than the entire car, thus causing understeer. additional eccentric. On a car with negative toe, or toe out, the lines initially turns in and when it is in the middle of a corner, the typical Front-wheel-drive race cars, on the other hand, are often set up with a bit of toe-out, as this induces a bit of oversteer to counteract the greater tendency of front-wheel-drive cars to understeer. closer together (positive toe) or further apart (negative toe) than aftermarket adjustable ones, Using a wheel alignment tool kit, you can achieve professional results in your own garage. optimal front camber also depends on how hard the driver accelerates and how Factory Alignment Specs. road course setup employs either zero front toe or minimal front toe in use the toe adjustment to balance the car. results in the tires becoming more vertical in the corners, thus increasing Because, when the front tires are toed-out, there is a constant slip angle on the tire and distortion, so when you turn the wheel the car instantly goes that direction. This is a problem that is particularly prevalent in the racing world. its rear tires following the front tires; it wil tend to be stable under He is a NASA Regional Champion and certainly knows his way around wrenching on front-wheel-drive cars. High power street car: minimally positive toe in on non-driven wheels, Last time out the car would 1.6 with first gear burnouts and low 1.7 with 2nd gear burnouts. in corners, making camber negative when the car is standing still Cars with double A-arm rear suspensions like Miatas can also adjust the rear In this video we discuss the pros and cons of different weight distributions for front wheel drive cars. The car is ready for the alignment. According to Craig, the fact the car is rear-wheel drive completely changes the rear toe settings from a front-wheel-drive setup. Front Camber: 1.5-degrees negative Idk where my car sits yet in the full 1/4 but it goes low 7s in the 1/8 and close to 110mph in the 1/8. the size of contact patch when it is most needed. And the drivers don’t like that, which will affect lap times.”. We have also previously covered how to use pyrometer data to make better-informed alignment decisions. With FWD and RWD drive covered, it was time to get an all-wheel-drive perspective. In less than 3,000 miles of driving, I have completely destroyed tires on a street car with a very aggressive autocross alignment. With just the camber and toe change and a practice event with 35 or so runs to really get a feel for the car I went from 5 seconds back (same at two events) to 1.5 seconds back of a new friend. A car with front toe out will initiate direction changes more easily than As you can see, the more power a car has the more positive toe it tends to Video: Scaring Mom In A Lotus Exige Cup 430 At Cadwell Park! “We run pretty much the same setup, a neutral setup for Spec Miata for cross-weights unless we are at Mid-Ohio,” said Jim. front camber, which can be useful as FWD cars often need all of the front What really makes a car actually turn is the tires’ distortion between the contact patch on the racing surface and the wheel. Street Legal Mario Kart! "Spirited driving" street cars or dual duty street/track cars A car with zero toe has the wheels exactly parallel to each other. However, a rear-wheel-drive car with an independent rear suspension and more articulation points and suspension bushings — like a Porsche 911 — will have some flex under power, which can change the rear toe angle. grip in the corners Camber in the rear of a car works on the same principles as camber in the front, If this is you, start with the "perfect" calculated camber angle, and then back off some static negative and see what happens to your times. Many cars do not have a way of adjusting the rear camber from the factory. Today we are going to look at alignment settings specifically as they apply toward the inside edges of the tires. adjustable ones. For a Spec Miata, which has independent suspension and rear-wheel drive, Jim agrees with Craig and runs toe-in in the rear. How To Do FWD Drifting Drifting is a driving technique , or a stunt more appropriately, where the driver deliberately oversteers to make the rear wheels or all tires lose traction but without losing control for the entirety of a corner. If I run any toe at all, I will add a millimeter of toe-out to the front.”, For Hondas, he just runs as much positive caster as possible. Marcel discussed what other drivers like with front-wheel drive, “Some people I set cars up for like a more aggressive setup. Caster only applies to the front (steered) axle. But, Dave has owned two Nissan GT-Rs and knows a lot about car setup. Jack and block the back of the car to compensate for the height of the front wheel alignment turn tables. Shorter wheelbase cars can turn much easier. Rear Camber: 3.5-degrees negative car balance, power level and driving style; toe can easily be the most A car with negative rear toe will want to control arms or Rear Camber: 2-degrees negative Front Toe: None (straight) Some drivers like a more conservative setup, while others like a Bonsai approach to corner entry. The idea is to replace a fixed length OEM link Rear Camber: 4-degrees negative weight is transfered to the outside tires, front toe has the opposite effect Video: This 1JZ-Swapped Lexus IS300 Is A Budget Track Beast. FWD track alignment 29-08-17, 04:34 PM. Getting it to rotate is a problem. mid corner direction changes, while front toe in makes the car darty Craig is an engineer, so if you let him talk, he will open up your mind to concepts you may not have thought about before — unless you spend your spare time hanging out in a physics classroom. on pavement. Therefore it is a good idea to try to obtain the desired balance via aftermarket camber/caster plates duty split and OEM camber adjustment range. Low power balanced track car: zero toe, front and rear. Marcel DeKerpel of DK Racing is the master mechanic of the NASA SoCal Region Honda Challenge scene (a region that has more Honda Challenge National Championships than any other). FWD track cars may resort to extreme amounts of rear camber to balance the will tend to make the car understeer - the rear tires will follow the front Jim agreed with Marcel that alignment setups are sometimes track-dependent. To see empirically why this is so, consider toe out. Other cars with double A-arm front suspensions like Civics can replace Front toe is generally adjustable on all modern cars via tie rods. additional eccentric. Adjusting camber (the tilt of the wheel) is a quick way to ensure you will have more contact patch on the ground during hard cornering. to adjust camber on the front axle. the rear tires otherwise, such as due to being required by the rules to a less significant consideration than tire wear due to camber. or an adjustable rod end. will want less front camber. Those three little adjustments front and rear are all there is to an alignment. As most cars are limited by grip Rear Camber: 3-degrees negative Marcel owns DK Racing, which builds and maintains most of the Honda Challenge fleet racing in the SoCal Region of NASA. We will start things off with Front Wheel Drive. than front camber on street cars (to maintain significant understeer) Craig Watkins was the engineer for Flying Lizard Motorsports and helped the team earn a pole position at LeMans. Rear tire pressure on FWD racecars - posted in The Technical Forum Archive: I would like to know if there are established methods of setting optimal tire pressures in the rear tires of FWD racecars. The following will produce a (more) oversteering car: Because nonzero toe scrubs speed on the straights, it is usually not desired. braking, especially when braking in curved paths. MacPherson strut cars would generally install drive car, rear tires continue to be loaded unevenly through much of the Low power drift car: negative toe, front and rear. - Modified Magazine Follow this guide to reduce that loading and you will go faster. (1/32"-1/16" per side). frequently would say that toe is the most important parameter to be correctly As long as the camber is not excessive in the sense that it begins to reduce Front Camber: 2.5-degrees negative He spends his days at his race shop, East Street Racing (ESR) in Memphis, Tennessee, working on customer race cars and provides setup and track support for Spec Miata racers. substantial toe in on driven wheels (1/16"-1/8" per side). Obviously wheel alignment, and in particularly toe settings, are going to be wildly different on a FWD grip/race car than it is on a RWD drift car, for example. The above discussion assumes a car going straight, with equal weight on on the front wheels. Allow me to introduce you to Marcel DeKerpel. minimally positive toe rear depending on car balance and driving style. the tire contact patch size under all conditions, making the front camber In cases when other suspension components are changed in on how hard the driver corners vs how hard they brake. camber they can get to combat the understeer resulting from In this in-depth video, Tim McAmis covers all aspects of front end alignment. I have discovered and developed the Dynamic Rear Steer(DRS) system for VW race cars that works for all racing situations. Learn how you can get your car's wheel alignment dialed in for maximum cornering grip for when you hit the track with our lesson on trackside wheel alignment. within their ideal temperature envelope, it can be more aggressive with the Photo 6/8 | S2000 rear bumpsteer kit versus stock toe arms. With the wheel in the air, you’re already at 100 percent load transfer, so start looking to alignment settings and tire pressures. eccentric bolts, camber/caster plates, etc. High power RWD/AWD track car: zero to minimally positive front toe, Schwartz Performance’s “Skart” Rules All, SEMA 2020: Miller Electric Offers New Enthusiast-Friendly Welder. corner exit and not just in the mid corner phase. Front Caster Adjustment. It is easy to illustrate how camber thrust works on a typical circle track race car. We will safeguard your e-mail and only send content you request. How much of that was the alignment and how much was the car I can't say, but the car was immediately easier to drive with the alignment. Build your own custom newsletter with the content you love from Turnology, directly to your inbox, absolutely FREE! Toe is whether the front points of the wheels on the same axle are to make the car understeer. However, it is rare to set up a rear-drive race car toed out in the rear, since doing so causes excessive oversteer, particularly when power is applied. around the car's center. A very inexpensive and easy way to get more performance out of a car is by merely adjusting the alignment settings. the size of tire contact patch is greatest when the car is not cornering Usual car suspension designs result in the outside wheel gaining positive more negative while keeping the rear camber fixed will make the car many track alignment settings are designed to move the cars closer to neutral The tire compound, in particular its optimal temperature range and Here, you can see the mechanic using a Smart Camber tool to measure how much camber the wheel possesses. Marcel has years of experience prepping front-wheel-drive Hondas and Acuras for himself and other drivers. run -3 to -4 degrees of camber. drift, or powerslide, and tracking straight is obviously a desired characteristic One other thing is make sure the alignment is where the camber hits close to zero when you launch. None of these wheels are pointed straight, nor are they straight up and down. On road courses this is required for stability in high speed corner entries and for than it does on the straights, making the car loose on corner entries off Front Camber: 3.75-degrees negative Now, if your goal is to go to the track and crush the competition, then use the information above to go out and set your personal best at your next track day. insufficiently, as the following picture demonstrates: In RWD cars, optimal camber setting for the front axle depends The FWD race car is limited by the dynamic loading of the outside front tire. Many cars do not have a way of adjusting the rear toe from the factory, For a start, the driver is always turning in the same direction, instead of being able to turn left and right, which has an immediate impact on how you need to align the wheels for the race. More rear toe-out for a loose feel? DNN prefers the more aggressive alignment settings with lots of rear toe-out to help the car rotate. via eccentric bolts. The late ’70s model Camaro was (and still is) an extremely popular racing car simply because its wheelbase is the shortest allowed by many local rules. Front Toe: 1 millimeter out, both sides (2 millimeters out total) Adding camber will make the rear of the car more planted in the corners. But how you dial in your toe settings is going to depend on your driving style, how the rest of your suspension is setup, and what type of handling balance you’re aiming for. by intermediate-level drivers run -2 to -3 run, especially on the driven wheels. A FWD oval track race car, like most other oval track or road racing cars, should be as near 50%-50% front-to-rear weight distribution as possible. FWD track cars may resort to extreme amounts of rear camber to balance the car by reducing rear end grip. Alignment comes down to setting up how your tires adhere to the road surface. Most of the discussion around caster centers on steering effort. On FWD. car by reducing rear end grip. Nothing says "triumph of enthusiasm over physics" like a FWD race car. The initial turn in is good but it can't hold the line and pushes wide through the corners. That is an incredible racing resume. Dave’s recommendation for an all-wheel-drive car was similar to that prescribed by Craig Watkins for a rear-wheel-drive Porsche — using static toe-in to keep the rear wheels pointed straight under hard acceleration. This clean Honda Challenge race car is the workhorse of NASA racer Marcel DeKerpel. with inside edges wearing much quicker than the rest of the tire. For a 911, you must run enough rear toe-in so that under hard braking or cornering (or both), if the wheels move into a zero or slightly toed-out condition, rear stability goes away. Many cars require aftermarket camber plates to adjust front camber. A common, though by no means universal, pattern is to have more rear camber tires, and will push the front tires forward in a straight line. “When we go to Autoclub Speedway in Fontana, I take all of the toe settings out of the cars to streamline them for the high-speed banking.”, Front Caster: As much positive caster as possible And if a car is a rear-wheel drive or front-wheel drive completely changes what those specifications should be at baseline. The Sweet Science of Front Wheel Drive Racing. presence of minor steering wheel movement, which is why street cars often The three major alignment parameters on a car are toe, camber, and caster. The same eccentrics adjust camber and toe; In the end, the driver will decide what he or she prefers when behind the wheel. By Jack Baruth. Marcel DeKerpel (in his baby blue Civic) chases a DNN Motorsports Acura Integra around Buttonwillow Raceway. Today, we will skip the alignment tutorial and get right down to the specifications you can dial into your car that can make you faster. They like 1/16-inch of toe-out in the front, each side, and 1/8-inch of toe-out in the rear, each side. substantially positive rear toe. handling, by making it oversteer more than street settings would. A McStrut FWD is pretty much the perfect storm of suck when it comes to tradeoffs between maximum cornering and maximum straight-line acceleration. We are going to break these different alignment specifications down into Front-Wheel Drive (FWD), Rear-Wheel Drive (RWD) and All-Wheel Drive (AWD). under braking (front toe) and acceleration (rear toe in a rear wheel drive car, You’ve heard about torque steer and “wrong-wheel drive” and might write it off as being for grocery-getters, not real performance cars. In drift cars, adding toe out is an easy way to get the car to oversteer more. On a road course front toe primarily affects eagerness of the car to turn which allow the ball joint to slide in a slot in the control arm, In addition to the tools you need to measure caster, camber, and toe angle, Summit Racing carries all the specialized wrenches, sockets, and other tools you need to make adjustments to your front end. from the front. A positive rear toe Instead of toe-out in the rear, he sets them up with toe-in. at a point forward of the car. However, mid corner either direction. Thrust Angle. “If I’m running Hoosier tires then I want 4-degrees of negative camber because that’s what those tires like,” said Dave. You will see the alignment specs vary depending on the drive wheels, especially when it comes to rear toe settings. Front-wheel drive gets a bad rap with car enthusiasts. “I like a square car, a car that has the same negative camber both front and rear. Marcel said setups are not only driver-dependent but also track-dependent. With all of this performance-alignment advice for different types of cars, I will leave you with this caution: All of these baseline setups are absolute tire killers if you drive your car daily on the road. Camber: What Is It And How Can It Make You Faster, The Pros And Cons Of A Sequential Gearbox, The Appeal of Pushrod Suspension: Why and Why Not. Front Camber: 3-degrees negative There is nothing to change in the back of those cars. All rights reserved. camber via eccentric bolts.
