The kind people at Pontiac asked that I post the following info to me on the GTO's wheels.

The GTO hub has a 5x120.00mm bolt circle diameter.
The offset is 48 mm for both 17-inch and 18-inch wheels.
The GTO wheels have 8.0 inch wide rims.


Incase anyone didn't know :afro:

you wouldnt happen to know the centerbore?
5x120 with an ET48 is recent BMW fitment and there are some beautiful and classy wheels available
