Camaro and Corvette wheels are 120mm x 5 lug pattern, so they fit the hubs. But, you need to be careful about the offset and back spacing to clear the fenders.

I'm not sure the hubs will fit. The lug pattern is correct, but I think you'll need to bore the inner hub to 69.6mm. These Holden -"Pontiacs" are a little odd when it comes to this. Still, these will look REALLY nice on that car-and if you have them PVD coated in Chrome or have them polished / coated...HOLY CRAP!

The actual hub (on the car) size is 69.5. The wheel hub (on the tire / rim / wheel - or whatever you want to call it) needs to be 69.6. Here's a link to the thread about wheel hub size...

Actual GTO Hub Diameter?

I've seen reports of both 69.5(on here and from TireRack) and 69.6. Can anyone tell me which is right? I have to custom mill the rings to fit. The wheels I ordered have a 79.5 bore diameter, but the rings they gave me are for a 67.1 hub(they didnt have a gto size). Thanks
