Stock 3.42s, and no I originally had the stock WS6 rims on it with kumho tires 275/40/17s, replaced those with the C6 Z06 replicas, but same size as the original wheels 17 x 9.5 on all four with same size kumho tires again. Now I have BF Goodrich tires on the back 2 after the alignment, but they're the same size as well, just a tad bit stickier but not by much.
