Fronts are the issue..I used to run 18 x 9.5 Enkei RPO1,s I think it was a low 40,s offset up front and I ran a 255/35 without any problems...(sans the 10mm bolt at the top)

Rears 265 sounds about right.

Rolled or untouched fenders? Big difference.

for a 9.5 would +17 or +27 sit best with 265 or 275

I've posted this before in my build thread--what I've found is great streetable flush fitment with rolled fenders that works for me is:

18x9.5 +33 front with 255/35
18x10 +27 rear with 265/35

That rear fitment is equivalent to a ~+20 on a 9.5 in the rear.

You could go with the +27 if you wanted to rock 275/35, with the option of a thin 5mm slip-on spacer.

You could also go with the +17 if you were cool with the 265/35.

hope this helps!

^ What would be perfect fitment if you didn't want to roll your fenders and you were on H&R springs? Or Stance coilovers

Add about 15-17mm front and back, so like a 9.5 plus 48-50 front and 10 plus 43ish rear. You may have issues inboard with the wider OEM shock/spring setup if not running coilovers. Definitely less room for error w/untouched fenders, especially in the front.

Thanks! Just experimented with lots of sizing combos over the years and found what worked for me

IIRC my last set of RPF1 were +45 all around. This time around I have a BBK in the front. So what you're saying is I can't run anything from 40 and down without rolling my fenders? I want a nice aggressive fitment but don't want to roll my fenders too much when I get new rims. I guess I will have to

'Nice aggressive fitment' and 'unrolled OEM fenders' are pretty much mutually exclusive

Rolling fenders isn't bad. Just don't get in a rush. I bought one of the Chinese rollers on eBay for 70 bucks or something and went to town.

If you have coilovers, IMO you should run more + offset than +27 if you want to avoid running "stupid" camber. That said, camber of 1.5, 2, 2.5 and even 3 degrees isn't necessarily stupid, depending on wants/needs/usage. I run -3 front, -2 rear street/track. With -2 degrees, I think 255/35-18 on +35 should fit up front with rolled fenders. With less camber, more likely to rub.

In back I'd definitely go +27 over +17. Why not the same +35 as fronts? Stock had same +50 offset all around.
For my FD, 17x8.5 +40 F, 18x9.5 +45 R for street wheels, no rubbing worries whatsoever and scrub radius much closer to stock. Flushness has never been a priority for me, but of course tastes vary...

Would you consider running +34 all-around and just using a 15mm spacer out back so that you can rotate?

With this, is it reasonable to say 18x9.5 +40 might work in front running a 245 tire without a roll?
