If you were wondering, i'm currently on GC07 Dimensions 17x7.5 +38 and i'm not having any problems with the tyres striking the fenders. In addition, with that dimensions on, the rims are perfectly flushed with the body, making the car look real stable...I was a lil scared if it would look good and I wanted to make the grille look more open . This is my first wrx, I had a gti for a while and the subaru stuff is way better. I am just watching and learning more about it. I dont know where to go for best for my buck. Very anxious to see how everyones comes together. And what wheels fit perfect with no problems? Thanks everyone!!!
