Hmmm thats interesting and reminds me that I noticed my trailing arms also have a rubbing mark from my wheels and kinda forgot about it. I think Ill have to take a look at the wheels and see which set was the culprit. Given this my money is on my 17x9.5 +38 NT03's. But if that is the case then given they're 3mm further away from the arm vs your 17x10 with a 3mm spacer you'll likely need ~8mm spacer to clear without issues.

I think a fabricated trailing arm would be ideal and sounds like the route your going but I also doubt its going to pose an issue at this point as its probably clearanced itself enough already.

EDIT: Something else to keep in mind which hasnt been discussed is actual flexing of the wheels not just bushing flex and I just remembered this. Its been mentioned in the past that RPF1's move around a good amount. So that too could be something to take into consideration and also makes it difficult to compare setups here as wheel sizes translate but wheel rigidity not so much...

It probably has self clearance enough now. But I'd rather not take the chance. And, I can gain a lot of clearance with trailing arms, then I won't have to run the 3mm spacer.

So I took this picture the other day. Its hard to see but if you look closely you can see the same notch on my LCA. This contact was absolutely with my 17" wheels and is because of the shape of the arm like in your case. So there you have it an even narrower wheel 17x9.5 +38 which is known to be stiff also makes contact...the wheel in the pic is my 18x10.5 NT03 and there is plenty of room as you can see.

I always assumed it was our bushings and maybe some change in toe at compression. That would be a TON of wheel flex.

I had that same rubbing with 17x10 rpf1 ET38. had 275 hoosier and it rubbed as well. I sanded the arm and it went away. I did use a 5mm spacer later

I already have a 3mm spacer.

It's all good. I'm gonna build arms, run no spacer, and the next set of tires will be 275's

Oh absolutely the majority is from bushing flex, agreed. I only mentioned wheel rigidity because they say NT03s are stiffer than RPF1's so assuming same wheel specs and same alignment ride height and all those other variables held constant the stiffer wheel may not make contact whereas the less stiff wheel may.

When they talk about wheel flex, you'r talk a couple thousandths of an inch. If the bushings didn't flex, the wheel wouldn't rub..


They'll cost the same as R/TErnie's arms if I were to sell them. I'm not trying to undercut the guy, I can just save myself money building them myself.

Yes agreed wheel flex is negligeable and probably 99% of the interference is from the bushings. My only point was holding everything else constant if my NT03's rub then the RPF1's will too but not necessarily vice versa.

And understandable I was just playing...I already fit my 10.5's at the expense of hacking up my rear quarters so I have no need for the trailing arms. But for people who want a 10.5 without destroying their rear quarters the PF01's with modified arms would be a good option as been discussed in this thread.

I plan on building these arms for that setup. Or another wheel, not sure yet. But CCW's would be legit...lol

Is there Post here that mentions if spacers are needed for the 18x I0.5 +30 nt03?
looks like I can make it work.
Only looking because I may have a good deal on a set.

No spacer needed in the rear, but fenders going to need a good bit of loving if you're running 285s or bigger on them. I dont recall what you'd need up front, but if its anything to clear rotors it wasnt much. I feel like my buddy had a 10mm spacer more about fitting the 275s he was on to clear the spring.

Thanks for the info!
Looking to go 18s to clear X brakes @ front and give more inboard room in the rear. I'd like to run a 275 NT01. I'll beat the crap out of my fenders, if I need to. Ain't skurred.
18x10.5 +38 is another option I'm looking into, though I'll be paying full price for the wheels.

I've got a 20mm in the front to clear the spring. Could probably get away with a 10 or 15 but pushing it further out gives more steering angle before rubbing the frame rail, just barely rubs a hair at full lock with a 20mm. They clear the calipers without the spacers.

3mm in the rear to clear trailing arm, getting rid of the spacer as soon as I get my new trailing arms.

I run 275 NT01 on 18x10.5 NT03's +30 on my Evo X with Ohlins.

Here are some fitment photos to help your decision: (all fitments below clear calipers on the Evo 10)

No spacer:



5mm spacer:



12mm spacer:
