I want to run 17x9.5 in the front and 17x9 in rear. I was wondering what offset I will need and if i need a spacer. The rim is Buddy Club P1 racing QF.

 

What offset options do you have? Up front you will need something lower than +30 so the wheel can clear your front suspension. Out back you need a +38 or +35 for the lowest without having fender clearence issues.
