What information do I need to look for wheels for an enthusiast model? I see the offset is 30mm for the front and 33 mm for the rear, now they are 7 1/2 and 8 inches wide, what is the bolt pattern, see that is required on tires.com?

 

you can go wider, as much as 8.5 in front and 9.5 in back, altho the factory wheels may be different, your car is identical to those with 18" from the factory, not certain about the rest tho.

 

You can go with 9.5in. at the front and 10in at the rear.

For the offset, there are spacers that can solve some of these problems. There is a limit in the front to about a 35*38 offset. In the rear there is more space available.
