couple of thoughts:
THe father to the front, the greater chance to scrape (been there done that!!!)
the corvette has the air dam that is almost like tire deflectors. It is all the way under the front nose in a straigh line w/ the front axle
Mine on the 02 Q45 is on the curved edge of the IMPUL front bumper.
The IMPUL body kit is aready 2 inches lower than stock and I was running my springs 1 inch lower.
I ended up scrapping the rubber dam right off.....
