I just installed a set of the Pro Comp 6001's last Saturday. First, we tried a set in a 17x9. BAD rubbing on the bottom rear of the front fenderwell when turning. So, we went with a set in 17x8 and they still rub, but very slightly and it's not a big deal. I run a 5" lift with 37's and if I was running 35's there wouldn't have been an issue. I would definitely NOT go with the 17x9's. I'm thinking with 315's, unless your running a 4"+ lift, your gonna rub. Stick with the 17x8's and you should be fine. I'll post pics soon.
