I want to get some 9J wheels for my 225 F1. I like the 2Forge ZF1 wheel, forged, light and simple. What offset would be suitable with a 9J wheel (18 inch)? I have seen Alex from Performance Only runs 9's on his R26 and I believe his offset is 52 or 54, however I'm sure that car runs a MK3 rear beam so he can run some rear camber. Thanks in advance
