. Toughest part is to get the car to keep rotating through the corner. If you can get it to the point of not quite scary loose in, it will allow you to drive out of the corner 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. 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 Speed Secret: Rotate the car to improve your corner entry and exit speed. I use the term rotate the car often. And some drivers are not exactly sure what I mean by that, so let me explain There is a limit to how fast a car can travel through a certain radius. Ask the car to go through a corner above this speed and it will break traction. Depending on the setup of the car, and the drivers technique, the rear of the car can lose traction before the front and cause oversteer For getting the power on early. Oddly enough, carrying the highest average speed round corners may not actually be the quickest way around a track. If the corner leads onto a straight it can be better to take a late apex, straighten out the car and get the power on earlier for a high speed exit (Diagram 2)
If you're setting up a FWD race car, and you can see this in historical VW Golf or original Minis, they often lift and inside rear-wheel... Same with go-karts with solid rear axles, they'll lift a.. - Disconnect the shocks, when possible, and the anti-roll bars. - Use blocks the same height as your scale pads to move the car off the scales to make adjustments. - Bounce the car at each corner to free the suspension from any bind, then roll the car onto the scales. - Make sure the tires are centered on the scales front wheel drive set-up racing technology. although i run a rwd car i've had a far bit of involvement in making fwd cars handle so here goes, you dont say what sort of car and suspension set up you have so i'm guessing a bit when it comes to rear spring rates but these settings took 7 seconds a lap of my mates fwd escort on the silverstone stowe circuit (sub 50 second lap I did a lot of left foot braking in Minis and other fwd cars (and some RWD car). It is ugly, it is not science, but it gets the car around the corner. The technique is to stab the brake pedal with..
The best way to drive a FWD car on track is to brake deep, turn in slightly earlier than usual, trail brake - to keep weight on the front wheels - and then straighten the wheel as quickly as.. Primarily because there's less opportunity to make gains in a slow corner. A 5% difference in speed through a 100mph corner means a 5mph difference. A 5% difference in a 30 mph corner means a difference of less than 2mph. Also, there's less handling required in a 'point-and-squirt' corner than in a fast sweeping one
This is one of the major considerations when trying to get side bite going into the corner. Chapter 23 Soft Right Front Spring. This is one of the major tuning tools used on dirt cars today. You'll need to understand how this whole system works. Chapter 24 Dirt Track Racing Tuning Example. This is where I go through a little track tuning example The cars are powered by an 850 horsepower engine that can turn in excess of 9,000 RPM. The engines are based on V-8 Chevy, Ford, and MOPAR power plants. These cars are considered to be the most sophisticated cars in dirt racing. They hit speeds well over 100 mph and slide around the corners of the track
High power RWD/AWD track car: zero to minimally positive front toe, substantially positive rear toe. FWD track car: zero to substantially negative toe front and rear, depending on car balance, power level and driving style; toe can easily be the most effective way to change the balance of the car. Low power drift car: negative toe, front and rear You are not getting power oversteer. I don't think there's any situation where you would want a welded diff in a fwd car for road racing. You really want an open diff under decel and a balanced amount of lock under accel (for your power level). Too much lock on either accel or decel don't let the tires spin at different t rates going through a.
Toe is a useful adjustment to ensure that as you turn the wheel in the corner you get optimum camber angle and that both tires are turning the car as evenly as possible. Toe is adjusted primarily at the tie rod. You can measure the toe by rolling the car back and forth, taking a measurement, making your adjustment, and repeating the process . In a front wheel drive car with a welded diff, it feels like the line is more of a constant radius circle segment as the car is accelerating flat out through it. Corner Exit: Power Overstee You toss the car into the corner, letting the back end slide. And then when the back end has slid out enough to get the noise pointed at the exit-that's the scary part, particularly in traffic-you.. • Driver threw the car at the corner to get through initial understeer - only cure is to educate the driver and/or decrease understeer • Excessive rear tire pressure • Excessive relative rear ride and/or roll stiffnes why your car does what it does.

To achieve a well handling track car, the side to side percentage needs to be as close to 50/50 as possible. Getting a front to rear percentage difference of 50/50 is also favourable. However, this can be changed to increase front or rear grip of the car. The very important percentage for a track car is the cross weight percentage A surface that isn't prone to deterioration through abrasion (asphalt) provides higher grip when the surface is clean. Surfaces that are prone to deterioration through abrasion (dirt and gravel) benefit from being swept clean by the tires (i.e. sliding) to get to the intact surface beneath the loose material. The act of abrading the surface also enters into this Its easy you are asking the front wheels to do 2 seperate things. 1- your asking front wheels to power the car foward 2- at the same time your asking the front wheels to turn the car. If you can get the rear of the car to help make the turn through the corner the front doesnt have to work as hard and you can can put the power down Plus a bit of understeer gives you a bit of safety if you overcook corner entry, since it's safer to plow offline a bit than it is to oversteer off the track (and potentially back your car into a barrier in the process). Point being, set your car up to have the balance that inspires the most confidence in you as a driver Joined Oct 4, 2002. ·. 2,354 Posts. #7 · Apr 18, 2003. One local dirt tracker ran a V-6 front wheel drive Pontiac against the V-8 powered Montes etc and laughed his way to the winners circle consistently. I think he fell into the best combination of power/handling for the particular track. Trees

In the last article, I talked about the uses of toe and how it affects both drivability and front-end dynamics. However, that is only one of the three basic geometric ways to move a tire on a race vehicle. Of the other two, camber is well-recognized, but for all intents and purposes, the least-understood. Dirt stock car right front spring. The last two articles in this series focused on the balance of left side weight and wedge and how they work together to get the car to turn smoothly through the corner. Now we're going to look at how the right front spring rate works to help maintain a balance while the car turns through the corner
. I've got a Clio 172 track car, basically with front wheel drive you can take liberties a little because unless you lift off suddenly you. On a wet track the car wants to kick the back end out, its pretty much dead weight in the rear with a FWD so it helps in the corners. This is what it felt like when I drove, some people may say different but for me it felt like the car handled better in the dirt. Also Jason I ran around 25-30 psi and that seamed to help How to Trail Brake. Trail braking is an advanced driving technique that we're examining in today's whiteboard tutorial. The brakes of a track car are so much more than just a deceleration device - they allow a driver to manipulate and alter the pitch of the car as they enter a corner and this is trail braking The front loses traction and the resulting undrsteer puts them off the road! Fwd had come a long way, but will never match a rwd, especially in really high hp/wt vehicles. Most of the V8 conversions end up with a much superior weight distribution than even the straight six., nearly 50/50. A V6 placed like mine will put you in at 48/52
Re: fwd irs rear toe. if you add rear bar or spring rate the car will loosen up . This is the result of the rear tires sliding @ an angle more that the fronts. Optimal slip angle is about 9* for most of our tires. For the FWD car to feel neutral and fast the rear tires must track out side of the front tires The yaw will help rotate the car into the corner and, with the weight more evenly distributed across all four wheels, will provide a very impressive amount of grip through the middle of the corner. The downside to this layout is that extra yaw in effect will make the car more nervous and finicky on the limit: going from a drift to a spin more. Occasionally, a slight lift of the throttle is needed to slow down just a touch, settle the car, or help a FWD car's rear-end rotate through a sweeper. But it's rare. Like I mentioned above, some. Track Conditions Reduce air pressure in the right front Cool, wet, soft tracks normally like 1/2 lb. at a timelower left side weights as well as lower cross weights. Increase air pressure in the left rear and right rear 1/2 lb. at a timeHarder fast track conditions Try the same compound tire on a normally yield higher corner
Posted December 23, 2016. When you left foot brake in a FWD car you can effectively control the brake bias: Let's say your bias is set to 50-50 front-rear. If you hold the throttle and left foot brake, the front wheels will overpower the front brakes, but the rear brakes can still act normally, and even lock up i usually would be saddened by another crx becoming a crappy track car, but after seeing the pictures of what you did, i am amazed. i sat there with my jaw on the ground for about five minutes. very awesome way to go fast. sounds like a blast to dirt race. make sure to get some video of the mad rex on the track The more horizontal a car goes through a corner, the better the chassis is at creating downforce. We'll cover this in a later article, since here we're covering the low downforce Skip Barber car. The ratio of roll stiffness between the front and rear axles affect the balance of the car, especially its tendency to under- or oversteer Each car in DiRT Rally 2.0 will either be FWD, RWD, or 4WD. Put simply, these refer to which wheels of the vehicle are powered by the engine. The three types all behave differently Local Racer Heading to Big Stage, Ready to Sling Dirt.

Dirt track racing is a form of motorsport held on clay or dirt surfaced oval race tracks often used for thoroughbred horse racing. Dirt track racing started in the United States before World War I and became widespread during the 1920s and 1930s using both automobiles and motorcycles. Two different types of race cars dominate — open wheel.

Depending on the condition of the track and your driving style, there can be two very different approaches to your chassis tuning. As long as the tires have near 1 to 1 traction with the ground, you should set up your race car like an asphalt car (see the Chassis Set-up At The Rear For. The thing with AWD cars is that they can be set up to behave a lot like a FWD or a RWD or split the difference. If you play with the center diff and push power to the front it will act more like a FWD and if you shift it to the rear, RWD. I personally like mine to be a bit more FWD than RWD
A 1/1 is a weak as it gets. Try these settings one at a time at different corners of the car to see the changes & how they affect the handling of the car. A 9/9 on the RF will tighten the chassis all the way through the corner. While a 9/9 on the RR will loosen the chassis all the way through a corner. A 1/1 will have just the opposite effects Speaking as a rally driver, oversteer is used all the time to rotate the car in negotiating turns. There isn't enough grip on gravel, dirt, snow, ice, etc. for the tires to do the turning through a corner at speed. Getting back on the throttle, transferring weight back to the rear tires, is the primary mechanism to settle it out Say the front lifts off at .9 Gs and the car is neutral. If you continue to corner harder, the rear will really have to take the entire extra load, and hence will become overloaded. At 1.2 Gs the rear is taking a bunch more load, and if you were neutral before you're oversteering now An additional factor here is getting the load on each tire optimized in a variety of dynamic states, such as cornering, corner exit, and so on. Chassis tuning and driver-control inputs are big here On oval track cars it can be desirable to create a situation where the left front tire turns faster than the right front tire. The Ackerman effect can help the car turn better through the center of the turn since it builds TOE OUT dynamically, thus eliminating the requirement of running a lot of static TOE OUT That twill make excessive drag
- Get good tires - good handling but not there yet - Super Glue Tires - so good that the car wants to go off the track while the tires turns, ie. creating the lift effect. Example. At a autoX or Track day. You can have the car #1 with least amount of HP/TQ against a car #2 with massive HP/TQ. But what happens is that Car #1 is ahead all times. Jamie Hughes here on Race and good Thursday evening to all of you. This is of course Hometown Sports Corner. You are tuned in tonight. We're going to recap some dirt track racing around the area for you. Of course, we had a big sprint right at M Motorsports Park. We talk more with you about that here in a little bit A car with a high PMI is like a rear engine, rear drive car like a Porsche 911 or a front engine, front wheel drive car like our beloved SE-R, same thing only the poles are different, so to speak. A car with a low PMI would be a mid engine car like a Boxster I drove on the Ring with my welded diff and it wasn't a nightmare but it understeered muuuch more, almost understeered myself into the armco at 80mph (yeah I know, the problem is the driver, not the car). Got fed up with the understeer and bought S14 visc diff, works a treat for the money spent. #14 Vova, Apr 13, 2009
shows any noticeable oversteer exiting a corner, the car behind will accelerate better off the corner and make ground or pass. Note that this applies only to pavement racing. Dirt racing is a different matter. Understeering: Understeer is a term for a car handling condition during cornering in which the circular pat It can be difficult to get used to, because if you're not careful when you tweak it the car can get really unstable and twitchy, but with a bit of fiddling and practice it makes it incredibly easy (and fun) to pitch the car into a corner, tap the brakes, and shift the back end out so you slide through turns while throwing massive dust clouds
The car pushes and moves up. On exit the car runs out of room in the groove and often becomes loose on the late exit as the driver overturns to avoid contact with the wall. Many times when you loosen the car up to get a better run through the middle it will hook up better on exit. A car that is loose on corner entry should be cured at all costs Running a deeper offset can be useful for slick track conditions when looking for more grip or side bite through the corner. Running a shallower offset will reduce side wall deflection allowing the car to rotate freer, which would be more beneficial in a heavy or rough track condition Wheel hop also can occur on corner-exit in slower-speed turns where a car is in a low gear and torque multiplication is high. To find out more about what wheel hop is, why it occurs and how to cure the problem, we caught up with Pete Epple, a marketing technician with BMR Suspension, a company that specializes in suspension upgrades for early.
Every month we get emails from travellers astounded at the price of car hire in outback Australia. They come to us begging for a solution to their dilemma: they want to hire a 4WD to see the outback and they can't believe how expensive it is.. Sadly, most of these people are planning to visit Ayers Rock or Alice Springs - and you don't need a 4WD for either In the fastest sections, getting a clean first corner (even if that means entering it 20mph slower and 0.5 sec behind) is HUGE in making sure you keep speed all the way through. Australia is a great example, where it has that stupid fast 5/6 section after the gate where you have a rocky cliff face on one side and trees on the other Set your car up for this turn and forget the rest of the track. I don't use the dirt on the backside of the corner as my apex but that's because I'm in a momentum car. A 260hp FWD will DEFINITELY need to get on the gas late and hard here so get your turning done early. There's definitely a huge difference between the line you drive here when. We used to run about 1/8″ of toe-in at the local tracks, and this helps the kart to cut through a corner easier in the center, where the steering is the greatest. Cars that do not have load transfer, such as legends cars, can be run with toe-in to great effect at tight-cornering tracks, such as Martinsville or Langley Then, turn hard and floor it until you start to drift. Control the drift by giving the car more or less throttle to angle the car. To drift a front wheel drive car, go 20-30 miles per hour, pull the handbrake, and turn hard. Always push the gas pedal down at least half way to maintain the turn. To learn how to drift other types of cars, read on
Here are several telltale signs: (1) the car ends up in the middle of the track, (2) the driver steers the car to the exit apron (rather than having it drift out), (3) the steering wheel is kept constant throughout the corner, (4) the throttle is not applied until well after the apex (5) if the throttle is applied aggressively too soon, RWD. Adding air tightens the car up exiting the corner, while taking air out loosens it up exiting the corner. RF (Right Front): Lowering it tightens the car entering the corner and loosens the car exiting the corner. Left Track Bar: while raising it creates more drag and downforce and helps the car get through corners faster. Gears Detroit lockers are primarily used on tin-tops. These cars have relatively high C.G.'s. When cornering steady-state, the inside rear tires are very light and they don't provide a large understeering moment. The 'terrible understeer' is largely based on people who haven't actually worked with differentials North Alabama Speedway welcomes the United Sprint Car Series (UCSC) for round four of the USCS Sprint Speedweeks this Thursday, June 11.

Car drifting is caused when the rear slip angle is greater than the front slip angle This is the definition of drifting, and a good drift is also achievable in a well tuned FWD car. A few years ago Christini sold $3995 add-on kits for KTM and Honda dirt bikes. In 2011 Christini began selling their own brand of motorcycles, with Paoli front shocks and Honda 450X-clone four. For the scientists: you want the linear accelerative vector to point inside the arc of the car through the corner to compensate for the momentum drawing the car to the outside. Under static friction (on a race track) the lateral grip of the tires does this work, while under dynamic friction we use the clawing of the wheels in a forward. Basically, it's when you going through a corner and let of the throttle, the tail starts to step out. In front wheel drive cars, it can help get you through the corner if it's controllable. In my old '91 MR2, it snapped so quickly that you sometimes couldn't recover (I had to learn to walk again after 3 months in a hospital bed) Remember to drive within your limits, and work up to speed slowly. Cold tires are very slippery, so give your tires a good warmup on the track before asking them to work hard in a corner. If there's a faster car behind you on the track, even if it's a Geo Metro, be cool, point him by, leave your ego in the pits and learn from him. Jef
