Needing some wheel specs.

[robertf]

So I'm really interested in a set of 18x8.5 and 18x10.00 XXR wheels.

Any clue what spec I need to ask for for the GN? I can't really depend on a dealer to know the right specs for our cars. Thanks for any advice.

You'll want to go to a custom wheel seller and download their measurement form, then measure your car. That'll tell you what offset you'll need to make it fit.

Going that big, there's too much variance in the cars to really give you a number that's guaranteed to work. You really need to measure and see what will fit under yours.

120.65 mm is the bolt spacing, 4.75 inches.

The wheels linked won't fit.

Their car fit calculator within that link says they don't fit GN's.

The wheels linked are just an example. If I read the thread correctly the Monte Carlo in the provided link had XXR's. I like that wheel.

I guess they make them with 10 holes in them for both 4.5 and 4.75 inch patterns.

Yep, I do hate the 10 holes though. Maybe I'll look a bit more.
