Corvette Black Motorsport 2 17x9.5 2 18x10.5....$61917x9.5+54 18x10.5+58 I have always been a huge fan of these wheels! My only concern is that they are probably a little heavier. Should I be worried? Is it going to make a noticeable difference? http://www.tomzwheels.com/O. E. ConceptsCorvette.htm Any advice would be greatly appreciated.
