When you order the kit, you could contact evan from tci. He helped me a lot. I am running a 17x9.5 with a 5.5 backspace. I wanted to run a wider tire for my build. I will have to shorten the front sway bar cause it does hit when the wheel is turned. I am in the building stages right now so I havent done that yet. The wheel I went with was the torque thrusts and the backpacking is a off the shelf backspacing. I will have to roll the fenders to get it to fit. They don't rub when turned but it looks like it could rub if I hit a bump when the wheel is turned at full lock. I have some pictures in my build thread.
