You might be OK on the rear wheels but dont quote me, I assume you are getting the Wheel Replica Deep dish rears, the offset is different than the AFS peice of crap Cobra replicas. I have the 18/10 rears from Wheel replicas and am not even close to the IRS bolt. I THINK the 17/10.5 have similar overall offset, but you still may need to shave the bolt.
On another note, let me gripe some more about them fricking AFS wheels, what idiot designed a 03 Cobra replica wheel that wont fit a 03 Cobra? What a bunch of braniacs!
