I got a quick question.. I got 17' konig tantrums on my 99 ls teg... I also have my car dropped 2 in.. The clearance is fine at normal speeds... But once i hit around 80-90 i hear a grinding sounds on my fender... i think its because as you go faster the car gets lower and my wheels are rubbing against my fender... im not sure.. any info on how to fix it or whats actally happening would be cool. heh

What size tires, rim width, & offset?
Have you looked at the tires, do you see visual marks? Where, inside or outsite?

Without knowing the basics its just a guessing game.

Higher speeds = more downforce and yes the suspension will begin to compress while the tire grows taller @ higher speeds.
