I was figuring 4" since the lower ball joints on the wide stance are a few inches longer than the ones on the RS
Nope, no cutting, not even a plastic trim for the 33s, and I could see squeexing 35s with minimal trimming, a helluva lot more room under the RS fenders, as for the red zu emblem, good idea on your behalf, and I think it looks great like that. I did screw up the decal, it has a few wrinkles. I need to get a new one and do it again...
