Worked on a shaking rig, no.
As to the surface question. Here is a pic from the location where the local BMW club runs their autocrosses.
Laguna is pretty smooth now after all the work they did to it.
Thunderhill, not so much.
Reno, so bumpy I though I was going to break the car and had to go off line to look for smoother pavement.
Do you have pictures or in car video? If so put a level on them for your sport laps and normal laps. I'm willing to bet you won't see a difference in the lean of the car. (provided you were driving both laps at the limit).
 I'm not a native left coaster. You are right though, they are nuts.
