I'm in the process of building a GL 1302. The engine is a 2110 EFI Turbo/ Intercooled. It hasn't been on the dyno but I'm estimating 275-300hp. I have a set of 3 piece Hartmann wheels. The rears are 18x9.5 ET 15. The tires are Nankang NS-II 265-35-18. My question is, is this to much tire for the car/engine combo? I have the Kersher Kafer Cup Style finders so fitment is not an issue. Below is a picture of the car with 17X8.5 Turbo Twist. These will go on the yellow car in the background.
