I was looking in to some o3 cobra rims for my 04 gt and was wondering how wide of a rim i should get in the front and the back. Ive seen people with 17 x 9 in the front and 17 x 10 or 17 x 10.5 in the back. Which size should i get on a stock gt rear end?

 

I would get the 10.5 wide rim for the rear and the 9 for the front. With the 10.5 rear you can put on a good wide tire and ger really good tracton (sp) fo launching off the line!!!
