I jizzed in my pants.

 

what offset would i need for 17x10 for the rear?

 

You can fit that wheel size under stock fenders with anything higher than a +55-60 offset. ASM Rear Over fenders increase width by 25mm so you'll need something more than +35.

 

Interesting...I've fit anything from 17x9 +22 to +40 with Z1 SS to NT01 without any problems and with no finger gap. Alignment is at -3 camber, 5.9 caster and -.10 toe for fronts.

It looks like from the pic that you have positive camber?

 

^^I think you're thinking of the rears...he's talkinga bout the fronts. 17x9 +35 with 255 is cutting it close. I'm running 17x9 +35 with a 245 up front and it's giving me trouble. I'll rub the front fender with full steering lock to the left or right. And it rubs going up driveways. Otherwise, it's fine. If I put a 255, it'll rub alot more. Aggressive fronts are scary cuz it's easy to jack up the front fenders.

 

No, I meant the front.

I had 17x9 +35 RE30 with 255/40 (RT615, Star Specs, NT01, and NT05) with the alignment setup posted and there's still room. This is with no finger gap and never rub.

But let me just say that I also shaved the fender "lip" to get another 8-10mm. And yes, fucking up a $2k set of fenders is scary.

 

ah i see. I shaved teh lip on mine as well. I think it's just my ride height though...i'm tucking about half an inch. If i raise it up and add more camber, i'll probably be good to go

 

^how much camber are you running?

 

OEM alignment lowered with pss9.

18 x 9.5 + 38 offset with 265/35 toyo t1r tires.

no rub just some big speed bump , i live in NYC.

no cut rear panel, just rolled all the way in , and relocate the bumper tab, that's the only place it rubs.

still not done it, i will try to rolled the rear panel more deeper.

 

IMO, you've not utilize the overfenders to its fullest potential (+25mm if not more). Cutting of the 1/4 panels is a must...or else you're just having it mostly for looks.
