I already touched the right side skirt on my ZR1. Nothing serious, sanded out. But I'm worried about the front splitter. I put in a call to Pratt & Miller about the Height control system they use & if something similar can be fitted to my car. I drive my car a lot & being able to pick the nose up 3" for driveways, gas stations would be nice. If it were my Z06, I would leave them off.
