18x10's
 

So in brief searching and from what I remember some of you guys are running 18x10's. I was looking at adding RPF-1's to my 18x9.5 nt03's but I wanted the word on what works and what you had to mod. Offset as well.

Depends on the rest of the system, but if you want a square setup then you need to err on the high side and space out. +35-+40 works but may need a spacer to clear the trailing link. Front will need enough spacer to clear the brakes and maybe shock. Im rubbing my spring collar right now, gotta trade hub camber for strut top camber.

I've seen a few autox and track guys run 18x10 +38. Requires 20mm spacers in front, and possible small spacer in the rear depending on what tires/size you plan. The guys with 285 Hoosiers ran a anywhere from 3-5mm spacers in the rear. You could also look into Eric's (R/T Ernie) custom trailing arms. He has been able to run 10.5s with 295 using the trailing arms.

I run 18x10 +18 all around. 275/35/18 Hoosier A6 and same size Nitto NT01.

Version Select Wide Body front fenders and rear over fenders.

Over fenders being the KEY in that setup, no way 275s on a +18 are fitting under stock rear (or rolled) fenders.

The RPF1s with 285s require 17mm or greater spacer up front, -3.5* camber, and a generous roll/pull. Rears I just needs a moderate roll with custom trailing links.

RPF1s in +38 need at least 18mm to clear, but 20mm on the safe side...and also easier to buy 20mm than 18mm. The roll and pull may be car specific, but I don't think it's necessary from my experience helping others fit them. Can't...err shouldn't roll/pull the alum front fenders imo. The rear requires a roll, but not necessarily the trailing arms. Hoosiers do run wider than some other tires, and would lightly polish the arms. It's cheaper to run 2-3mm spacers than buy the offset trailing arms if clearance is an issue. :lol: To run 10 inch wide as the OP would like doesn't require much more work other run some rear in-board clearance of the control arm, but again comes down to tire choices.

Funny you start this thread, I just received my 18X10.5 NT03's in a +30 offset. No spacers needed at all, and it just barely clears everything with my 265 BFG R1S's.

Only place it rubs is at full lock on the inside frame but it's not much and will just polish off some undercoat. The rear's are close, and I have already cut the inner fender lip off so no issues there. I did smoothen out the rear trailing arm edge so nothing sharp would catch the tire under tire deflection.

Why do you say that? Mine are rolled/pulled 0.5-0.75" with no issue. Even with -3.5* I wasn't fitting 285s with an effective 18mm offset (20mm spacer) without the pull. Cost me around $150 to have all 4 pulled at my house by a friend that's done 100s of cars by now.

I've had bad experience myself, as well as heard from others about doing that to alum fenders. If it worked fo you, great!

I didnt realize how big of a pull my car had till I tried to put stock wheels back on without a spacer. Then tried parking and comparing to a stock evo, huge difference. Maybe I should take some pics some day.

Quit holding out on us and post the sh*t up! :D

Matt, I had 18x10.5+18 rpf-1's on my car with the stock body running 285 a6's. It took a evo dave front fender mod that I made myself and a lot of pulling in the rear. It takes body work to make it look good but it can be done. Also you have to move the rear bumper bolt back and cut the bumper some. Text me and I'll send you pictures.

It's alllllliiivveeeee! You working for Kevin now or doing something else down there?

Thanks for the feedback guys. I don't plan on running larger then 275 for points but I know a 10 over 9.5 will give slightly wider track and slightly better grip thus slightly better lap times so i'm trying to figure out which 10 is an option. RPF's seem the proven choice, I don't think they make NT03's in 10, just 10.5.

Care to post pics with the front bumper installed?

whats the deciding factory between 18x10 and 17x10? i believe both r1's and a/r6's are available in 275/xx/17. ive been contemplating this since i wanna buy another set of wheels in prep for things to come.
