Car is lowered on springs (will be getting coils very soon)
I rub slightly on full turn and whenever I hit bumps in the road lol
Friend wants to trade his 265/35/18 for my 245/40/18 tires
We both have RPF1s

My F/R are rolled

I did a quick search and found a post in 2009 :-/ https://www.evolutionm.net/forums/ev...ock-strut.html

Thanks ahead

That offset is too low in the rear. Sticks out too far. You will have tire to fender contact on compression unless you do some very aggressive pulling.

I run 18x10 +35 in the rear with 265/35/18. Fender lip is rolled slightly and I don't have much more room to grow outward. 9.5" +15 would stick out 14mm farther than my setup. No way I would run that.

Would 255 fare a bit better? I like a little more meat lol

My second set of wheels is 17x9.5 +38 in the rear with 255s. Your 18x9.5 +15 would stick out almost an inch farther, which is way more than I'd be comfortable with.

I should also mention that I have 2.0 degrees of camber in the rear. If you're running lower camber for street use, these won't even come close to fitting IMO.

Yeah, +15 on the stock body CT9A is only run by those wanting that Stance set (which is Ok if that is what youre looking for)

+15 does not work if you want the full articulation of the rear susp

As an example, I run a Federal 265 on a +29 wheel & had to perform all the rear fender tricks to get that assembly to articulate properly w/out rub

i think that is abouuuuut how far my 18x9.5 +28s are sticking out if i calc'ed that correctly. what wheels are those?

Construct

RPF-1 in 18x10 +38 with a 3mm spacer to keep it off the trailing arm. Net offset is +35.

Your 18x9.5 +28 would stick out 1mm farther than my setup.

Clearance to the trailing arm is close. I'd probably have to switch to a 5mm spacer if I used tires larger than 265.

ahh. yea this setup is pretty much on the very edge of what's possible in the rear with rolled fenders.. that's the biggest difference i've noticed between newer and older cars. e92 m3s can just slap on 10.5's stock.

Im gonna put my rpf1s up for trade for MR X BBS lol

no matter how much research I do, I keep coming back to that wheel with 275 NT01s. All other wheels need spacers anyway or cost way too much. RPFs are light, so that's a bonus. I just get tired of looking at them. 😂
If only the NT03 18x10.5+30 would work in the rear along with not needing much spacer up front. I love the look of that wheel.

I haven't found anything that strikes a better balance of fitment, weight, cost, and strength than the RPF-1. That's why I ended up with two sets.

I really don't mind spacers. I trust my ARP extended lugs more than the stock lugs. I bought some nice, custom hubcentric spacers that center the wheels nicely during mounting, too.

kaj

iTrader: (60)

Absolutely. I have all that, too.. I just like mounting directly to the hub (preference, but no biggie). I read RPFs flex a bit under heavy load, but it doesn't seem to be a bid deal either. I don't daily on my track day wheels, so I don't have to worry about my car getting lost in the sea of hard parkers at the local Cars N Coffee.
And yeah... that price. The only other wheels in the price range are much heavier and possibly not as good quality. It's a no-brainer, really. One day I'll get some custom 18x10.5+44ish wheels.. until then, RPF it is.

Yeah I found a few Advan GTs and TE37s in 18x10 +40 and +41 fitments, but it's crazy realizing I'd be paying over $2,000 just for the fact that they aren't RPF1s. From what I gathered many CCWs might even be a little heavier.

But it's also sort of like living your whole life in sweatpants. Just imagine a world without RPF1s, where we're left with countless affordable 20lbs wheels to choose from without second guessing the decision.

iTrader: (60)

Our choices could definitely be worse.

Any thoughts on the enkei RPF1 in 17x9.5 +18 with 255 tires? How would those work on an Evo 9? Will I need spacers, etc? (I do plan to put on some coilovers later...)
