I bought my wheels here and used this fitment guide. Its somewhat out of date as it doesnt show new wheel lines but here ya go. http://www.forperformance.com/fitment.html

 

I wouldn't run 9 x 17s all the way around with a 40-mm offset UNLESS I ONLY use 245/40-17 sized tires and roll the front fender lips... Forget fitting a 255/40-17 on 9 x 17 with a 40-mm offset YOU WILL RUB with a lowered ride height FD!

 

I think those fitments are for Stock suspended cars ONLY. I will be lowering my car but tire size has alot to do with it. I also was told these fitments were conservative. I do not know if thats true or not. They came directly from VOLK.

 

The offsets are aggressively biased toward the fenderlips, rather than inboard toward the springs and trailing arms.
