Weight over the drive axle comes in handy traction-wise when a vehicle is stuck in snow or sand. For acceleration and applying power when exiting a turn, a lighter car has less mass to heave into motion and is less hamstrung by inertia. In other words, a lighter car with the same power will accelerate away from a heavier one off the line with less wheelspin simply because the tires have less dead weight to struggle against.
