What is the width and diameter of the rims you plan to use? Are they OEM Z06 wheels, or repros? The wheels are generally sold with an "offset" number specified.... that's what you need, and that varies with wheel width (and to some extent with diameter, at least for the front wheels).Fred

The 17x9.5 OEM Z06 wheels have a 54mm offset. That is correct for your car. It will have about a 7.34" backspace. The 18" Z06 wheels can be a problem, because they have excessive backspace. The 18x10.5's have an 8.00" backspace, and will usually put the inside edge of the tire into the inner fender lines.Fred
