Torq-Thrust offset
I have a "93 and was looking at the American Racing wheels websites. They have Torq-Thrust II offsets listed for the early C-4's, but not the later ones. They do however, have a listing for 93+ Camaro/Firebird. The 17x9.5 offset is 46, and the 17x11 offset is 45. Will these work on my '93?

The OEM 9 1/2" wheel offset is 56mm so the T-T wheels are off by 10mm for the 9 1/2" wide wheel. That's a 10mm difference so there should not be any problem for this width wheel.
The OEM 11" ZR-1 wheel has a 36mm offset but the 1996 Grand Sport 11" wheel has a 65mm offset. There was a 3" difference in the width of the ZR-1 body at the rear end compared to standard C4's so that was the reason for the difference in offset for the OEM wheels. The chances are that the T-T 11" wheel with the 45mm offset may stick out beyond the fenderwell lip.

they will stick out approx 3/4". I have 315's on 11" with the 45 offset in the rear. The front also is sticking out the same so it looks OK. contact Luke at tire rack over on the tire/wheel forum for his expert opinion. he will be able to answer all your questions..

I just went down to Discount tire and ordered a set of them. 17x9.5 and 17x11. I also had to order new rear GS-D3's to fit the rear rims. I'll post pics when I get them next week.
