No the +18's work on the front w/out spacer but running them in the rear is not recommended IMO

The go-to set-up is the RPF1 17x9.5 +38 w/a 20mm front spacer. That is the golden RPF1 spec in my mind

I agree with MinusPrevius. +18 in the back = Mexipoke.

that +18 is 5mm further out than a 10.5 NT03

Where are you guys finding that calculator? I'm tired of adding +/6mm increments in my head.

So, it seems like best thing to run would be a 265/35-18 with a 18x9.5 +35 wheel? Also, this requires a 20mm spacer up front for brake clearance, correct?

9.5" wheel with +38 offset and a 20mm spacer up front is a common setup.

A +35 wheel will stick out 3mm more. Not a huge difference, but you'll want to check your clearance to the fender lip on compression. Might need more camber and/or some fender lip rolling.

Sorry, I was referencing available RPF1 sizes.

My car is at a trustworthy body shop awaiting wheels to clearance the rear fenders. I've showed them the Mullerized fender rolling thread on SocalEvo for reference on what basic things need to be done in order to have proper fitment.

Can't get 18x9.5 +22 TE37s in the color I want and it seems like (by using the calculator) that the RPF1 18x9.5 +35 is an easier fit. Unless the rear suspension has conflicts with that setup.

I used the calculator on another common RPF1 setup: 255/40-17 (?) on a 17x9.5 +15 and it shows that it pokes 20mm more towards the fender than the 18x9.5 +35 on 265/35-18 setup.

Thanks! I googled the wording on the calculator and came up with the same sight!

18x9.5+38 is the RPF size. They don't make that wheel in a +35.
