I agree. If you dont mind being slower due to the added rotational mass of the 18 or if u have plans to add engine mods to compensate, 18 are fine with springs. Otherwise do 17's.I would go for the lightest 17 you can find in a style you like, better performance and a little bit of a better ride. Never been impressed by the big wheel look.
Gun Metal with out a polished lip would go a long way to blending the black rocker panels. A polished lip will bring out the chrome that surrounds the windows. Especially if you have smoked tint which is pretty much the color of gm.Ill see what ill do,,, it also kind of depends which rims i will get, some rims have different lips, and the other might just look good as 17' all depends
so cleanThese are 18's.
