A couple pages ago I asked if anyone knew whether adding kickup to the front suspension would do any good.

After some experimentation with several FWD vehicles, I can say 1-2mm of front kickup definitely does help. The tires chatter much less on acceleration, presumably because adding kickup makes the suspension extend when accelerating, which jams the tires into the ground and reduces wheelhop.

I haven't played with rear kickup yet, but on the smooth tracks you guys drive on, there's probably no benefit to rear kickup. On rough pavement it may help smooth bumps a bit.
