Dark, I understand not wanting to spend $$$ on rims. I'm not a big fan of my '06 rims, but I'm not a big fan of the money required for some nice BBS either. Maybe I'll get a big bonus soon...
As far how many rims fit our car,
The Tire Rack - Your performance experts for tires and wheels gave me a pretty lengthy list of rims. Not all have the exact same offset as stock but they appear to fit just the same. My only head-scratcher is if the offset is different but yet is still compatible how will that look on the car? For example, the BBS RGR.
