Makes sense in my mind........I think
Bump steer works regardless of track and conditions. On 180s, chicanes, or sweepers, it's still going to make toe changes. Suspension travel happens every time you turn, brake, acceleration, etc.
For instance, I spoke with Craig Xavier at length about this when I first started running the Type R. My first week with the car was on carpet at his home track. After my first run with the car, he said, ADD SHIMS to the steering blocks. It will help the car enter the corner. I was in the same boat as you not understanding why. I will say this... it made a huge difference. The car definitely turned harder when entering a corner. This was on a small carpet track.
When Larry and I were setting our cars up at Jackson, we needed steering. That was one of our tuning tools.
This can make the car difficult to drive and very touchy. It's not for everybody. It depends on your driving style. I like a car that responds instantly to minute wheel movements. The bump steer helped.
Hope that helps.
Any other setup gurus care to chime in, please do so.
