i'm running 17x9+30 235/45/17 KU36's
-2 front, -1.2 rear
lightly rolled guards
345mm eyebrow all round
6kg front, 5kg rear
diameter will be 1mm less, width will be 30mm more.
you will be running more camber, and more of a rear guard roll than me, should be fine, fronts, should be fine, want me to check inner clearance for you? what height will you be running?
Troy might be your man.
My mechanic ran 34GTR rims, no issues on a 32GTR, so I assume with rear guard work and your front gtr guards you should be fine.
how come you are running 18's, and a 265 on a 9?
why not 33GTR rims with a 235?
