The bu bolt pattern is a 5x110 . The thing you need to watch for is the offset. The offset is 40mm. Some wheels wont fit due to incompatible Offset. Sites like Discount Tire etc usually have that info.
My first pick from Konig was an 18 ionch version of the wheel on my Avatar. But the offset of the 18 wouldnt fit. So Im going to go with a 17 when I get the car. The dealer said they would take off the 18 inch tires it comes with and put on some 17's from another car.
I have an 09 LT2 in the new version of WHITE ordered with the Ebony interior. I wanted the LT2 since it comes with body colored door handles. Im not a connoisseur of Chrome much. Now looking for a way to cover the chrome trim around the windows with a black matte that matches the B pillars.
