Yep 9.5" +38 is pretty much flush, should make use of every last mm from the guard with a 275 rear tire. Also the front is a similar fare. I'll be sure to post more photos once I get some quality tires on them.
I ended up buying a set of RPF1's for my 2012 FPV GT MKII although still have plenty of tread left on my current set of 19's with Bridgestone RE11 tires so no tires fitted yet. But here are fitment pics of 18 x 8.5 +30 Front 18 x 9.5 +38 Rear It just clears the rear control arm bolt mounts. Around 2-3mm clearance. Wouldn't be an issue with 19's or 20's. Front Rear
Here I go first post... Does anyone know if the Enkei PF01 (or RPF1) in the following wheel and tyre size 18 x 8.5 + 30 F (245/40) 18 x 9.5 + 45 R (275/35) Will fit on a SC'd FG GT? I want to switch to a light 18" all black rim on my next tyre change to maximise handling and these seem the go. Cheers
