Ram mount scratched the dash plastics during my first track day session that I used it before I learned to cover potential contact points with painter's tape. The fake alcantara on the steering wheel and shift knob is very flat but I need to try a cleaning product on it to see if that helps. No interior rattles for me yet (knock on wood).
The exterior already had paint chips from the previous owner on the front bumper, lower hood, edge of roof just above the windshield, and various places around the rear wheels. I have added more rock chips in those same areas during track days even with Zl1addons rock guards. The paint chips easier on this car than on several previous cars I have had, but the tires are also stickier which doesn't help.
I also learned that the SS 1LE front splitter is made of thin hollow plastic that cracks easily. The unpainted black ikon motorsports replacement copy splitter I got seems more durable but time will tell.
