Howdy Folks!

Does anyone have the offset and backspace of the actual Z06 wheels? There are some numbers circulating on the C5 fitment aftermarket products, but I searched and couldn't find OEM specs.

Thanks!

I'm pretty sure about this..

On the front 17x9.5 has a 54mm offset
On the rear 18x10.5 has a 58mm offest..

To double check your arrangment, take off a front and rear wheel from your Z, GM stamps the spec's on the wheel

Howdy!

Thanks for the response - FWIW, I know the specs for the C5 derived Z06 and you're right on!

Front: 17 x 9.5, 54 mm offset, 7.2" backspace
Rear: 18 x 10.5, 58 mm offset, 7.9" backspace

But I'm looking for the specifications for the _new_ C6 based Z06 - the 18x9.5 / 19x12 setup.

Thanks again!
