'06 Bolt Pattern

Hey guys. New to the site.

Quick question--

I'm seeing a lot of conflicting posts concerning 5x114.3 vs. 5x115 bolt patterns. I believe it is 115. Does this hold true for the '06 Grand Prix's as well?

Thanks.

Bolt patterns on the 97-03's are 115, I would imagine they would carry over to the following years also.
The 114.3 size is the OEM size for the Mustangs, which some have bought the Mustang Bullitt wheels for their GP's (like myself).

I've got an 04 GP and my chip foose wheels are 5 x 115.

Official bolt pattern is 5x115 but you can sometimes get away with 114.3 depending on wheel design. Some people have had great luck running it while others haven't.

It's really up to you to test fit it before you mount tires - since most wheel places will accept returns until you mount tires to them.

I have a 04 grand prix with 18 inch rims. the pattern is 114.3 and they fit fine with spacers.
