Need a little more info first.
As for average, that depends on how much wheel spin you're experiencing now.
But, you'll see a bigger gain from relocating your "IC" Instant Center, the imaginary line where, if extended, you're LCA's centerlines cross the driveline centerline.
If the IC (crossing point)is located in a more frontward position of the car it's b/c the LCA centerline in nearer to parallel to the driveline, and we'll experience wheel spin and hop, notorious to us 3rd Gens.
But if we lower the rear of the LCA mounting point by special brkts, the IC is effectively moved rearward PLANTING the tires by lifting upward on the car instead of forward.
This can easily add 4-5tenths! to a healthy 3rd Gen.
The sticky's will help too ofcourse set at roughly 13psi.

they can even make your car slower if the tire is too big and makes your gear ratio's to tall.

Do you spin a lot? get slicks?
if you don't spin, don't bother.
