I've got 600 miles on my Z51 and I just noticed a significant number of scratches just behind the wheels, front and rear. I've only driven on paved roads and parking lots. Do the wider wheels of the Z51 makes this more of an issue for Z51 owners? I was shocked at how much damage was done in such a short amount of time. Clearly I need to get some mud flaps, but the ones I see from GM don't seem to flare out that much. I'd like to find all black- not carbon fiber and I'd like them to flare out enough to insure the car is protected. Any advice is much appreciated.
