my point is that if just -1- left hander on the whole track is hard to control then its probably your line/inputs that are causing the over steer, not bump steer.
Well Its not just that one corner. But Its that corner were i notice it the must. Another on is coming out of the S turn and heading to the bowl. Have to do some correction there. Also the 4th turn befor the last one i have to correct for that to or I spin out.

I thought AP2's really didn't have a need for a BSK. Someone correct me if I'm wrong.

bumpsteer is not lift, bumpsteer is when the wheel "straightens" in the air after leaving the ground instead of landing in the direction it "took off" with...

the tire doesn't have to leave the ground for bumpsteer to come into effect. a better description would be that the steering angle of the wheel (the toe setting) changes as the suspension compresses or decompresses. so as you hit a bump while turning, the left and right toe settings change and the direction that the rear are pointing changes from the direction they were pointing before the bump and you either correct it through steering or spin out.

yes that's a more accurate description of the weight coming off the wheel allowing it to change direction.

the effect is most pronounced (more felt by the driver) however when making a high speed turn, a bump is hit and the wheel catches air - then the change in direction upsets the car significantly on landing...

Thats funny after all that from people suggesting that i dont know how to drive, to explaination of bumpsteer. No one has answered my questions yet. Has someone used the kits I mention? Will it stop this problem? And which one should you use for my application?

bumpsteer has nothing to do with if the wheel is in the air or not.
