Took this from another forum where someone asked pretty much the same thing. Credit to Pete.

Let's think about this for a second. What you need is grip. How do you get grip?
More surface area. This would equal wider tires and zero camber.
More pressure to the ground. Of course the easiest way is to add weight over the driving wheels, but who'd want added weight? However, you could move the engine back, and have the gearbox at the rear axle instead of the back of the engine, but that'd require some serious modifications. An easier way to achieve this is to build a suspension geometry that raises the rear instead of lowering it when accelerating. A force equal to the force raising the rear will be applied to the ground. This, however works vice versa when decelerating, so when you brake the rear will drop and the grip will be lower.
So, we've established that the suspension is working while accelerating. You don't want it to work against you, right? Therefore you'll need a suspension, that'll keep the camber same (zero), no matter how high it sits.
Last but not least, for optimal acceleration, the grip must be optimized between the tires. A cunning torsen diff, a spool or a very tight LSD would give you this, the last 2 mostly in drag stip conditions though. If you want to get all anal about it, you should also balance the weight of the car (with the driver included), so that it divides equally to the rear tires
