k so i just spent the last 25 min looking to see wut wheels fit the SS/TC and no one seems to have posted the answer im looking for CLEARLY and 18 x8 or an 18X 8.5 SHOULD fit my main question is wut OFFSET does the TC need to clear the front caliper?

go to tirerack and do a search on your vehicle..there are only 18 different wheels that will come up but tirerack guarantees them to fit (have actually been put on a ss/tc before). What I found out when I bought rims the first time around is that even if you have the right specs, there is still no guarantee that the wheel will clear the caliper....

 

It's not about offset. It's about the rim being a high disk. Meaning the spokes are further away from the mounting flange.
