Notice the wheelie bar behind the car in the video. Such vehicle would not run such time's with out it. Besides all the common negative effects of FWD such as under steer, torque steer, wheel spin, wheel hop.....Ect....... There are also the weight transfer side effects. The weight transfer is very visible up-on heavy ecceleration, as the front of the car lift's and the rear end push's down.

Although FWD vehicles have most of its wight on its drive wheels. Upon heavy ecceleration most for the down-force is lost due to weight transfer. Because of this, when we accelerate, we take weight off the front wheels and put it on the back wheels. But this is a FWD! Those front wheels are what are driving the car.

So what happens??? The harder we accelerate, the more we unload from the fronts. The more the fronts are unloaded, the less grip they provide. Eventually, so much weight is transferred rearward that the amount of power we're trying to put down exceeds the amount of grip we can provide, and the wheels starts spinning.

Once that happens, the amount of grip plummets (a spinning wheel has much less grip than a non-spinning wheel) and the rate of acceleration drops. When that happens, weight transfers forward, the grip level rises, and eventually the tire bites again - and acceleration increases, weight goes rearward, the tires unload, and away we go again.

Weight transfer off the drive wheels inherently limits the performance potential of a FWD car - and the harder you accelerate, the worse it gets. There is NO performance argument for using a FWD, not if you can use a RWD or AWD driveline and get down to the same (or close enough) weight.

The FWD drive-train was introduced by the auto makers for two reason and two reason only - packaging and, cuting cost. With a FWD driveline, all the drive parts are forward of the firewall. You don't need to accomodate a transmission or driveshaft hump in the c0ckpit, so you can make more interior room for the same external dimentions. Also less drive-train equals less cost. Performance was definitely not a factor and now people are doing what they can with what the factory offers as "performance" cars.

There are very good reasons why makers of true performance car's such as Porsche, Lamborghini, Ferrari, Ect, have never utilized the FWD drive-train. A FWD car is its own worst enemy from an engineering perspective. A FWD drive-train is inferior in every aspect when it comes to performance, no matter how you argue it.

Also notice the very few poeple who are running 7's in FWD vehicles all have a wheelie bar on the back, amongst many other drive-train modifications. By utilizing a wheelie bar thus helps minimize the weight transfer to the rear wheels but, does not remedy it completely.

actually a wheelie bar on a front wheel car works. it keeps the back of the car from compressing and taking weight off the front and losing traction. the wheelie bar doesnt stay off the ground the ones for front wheel drive it actually lifts the back of the car up a lil bit putting more weight on the front.

to clarify the wheelie bar,
wheelie bars on FWD cars nowadays are designed to eliminate the rear suspension. I will be running a 10lb spring in the rear of the car with very small struts. I want the rear of the car to compress as fast aspossible, this does 2 things; 1st it plants the rear wheelie bar onto the ground forcing all the momentum forward through the chassis and into the front wheels. 2nd new rules eliminate the wheelie bars from touching the ground before or after the run. using an ajustible rear strut and a soft spring you want the rear strut to compress very fast and extend slow so by the end of the run you are on the wheel bearings and the bar is lifted.
