SB - Audi Tt Coupe Independent Car Review My Opel GT had a couple of modifications from a stock configuration. First, it had 13-inch alloy rims from American Racing that allowed it to carry wider tires. This helped the Opel GT handle better, but the tires could bump the inside walls of the wheel wells on tight turns. Second, my Opel GT also had a small Weber Carburetor with a foam air cleaner. Like many pieces of equipment on my Opel GT, Fri, 17 Nov 2017 21:06:32 UTC en
