18x9.5+15 and 18x10.5+15 clear bbk on the 370z actually has a pretty solid fitment upfront. I have a set and ran them with no spacers

question, so i had a set of rpf1s, in the front 18x9.5+15 upfront. I loved the fitment it was great, so im currently trying to match that since i have the 18x9.5+38. For the same fitment would i have to run a 25mm spacer? Since 38-15 is 23? Is that how that would work? I would have tried to 20mm but Z1 doesnt have it in stock

Yes, your math is correct. 20mm or 25mm spacers will give you what you want. There are plenty of vendors besides Z1 that sell 20mm spacers.

Aodhan DS06 19x9.5/11 +15 f/r fit over akebono sport brakes on a 370? Want flush fitment with having to roll/pull fenders, would like to stay away from using spacers if possible as well. Can't find any info on these wheels with the same brakes. All results are for 18s...

275/35/19 on a 9.5” ET20 front wheel lowered on Eibach springs.
I’m running 305/30 in the rear. I am running a 255 front tire now but I don’t like the sidewall stretch.

Will the 275 fit?

The 275 with fit the rim nicely. I ran the 275 on the 9.5" rim for awhile. I don't know about the rest of the fitment.

It will definitely fit. Though, most run 265/35 with 305/30.

Will the 265 have sidewall stretch? I really don’t like that look.
I made a mistake and allowed my wheel vendor to talk me into 255’s
They look very stretched. That was 700.00 down the tubes.

Keep in mind that you will see slight dimensional variances between different manufacturers and even between different models of tire from the same manufacturer. Search for images of a 265/35 on a 9.5 wheel. You should be able to find a ton.

Just wanna double check what a vendor is saying will fit...
Forgestar F14
Front: 19x9.5 +20 with 265 tires with coilovers set to about the same height as swift springs.

Yes, will easily fit

Friend is selling a set of 2017 oem gtr rims...i know previous gen's have fit anyone know if these will without spacers and such?

Stay away from OEM gtr wheels, weak spec

in what aspect? Initially I was searching for 18x10 +30 / 18x11 +18 I believe these are 20x9.5+45/20x10.5+25 with 275F/295R just seemed like a fairly similar set up to what I desired aside from being 20's which I am a little unsure about but, I am no tire expert so maybe I am even looking for a bad set up to begin with, open to critiques

Your initial specs are weak
Read here:
http://www.the370z.com/wheels-tires/...tart-here.html

Your initial search for 18" sizes is almost identical to the popular 19x9.5 +22 and 19x10.5 +12 setups that people like to run. The OEM GTR sizes are not similar to your initial search.

Hey guys, had a question about the Enkei RS05RR. Looks like quite a few people have fit these wheels, but was wondering if anyone knows if the 18x10.5 ET+35 clears the front calipers without issues (sport package akebonos)? I know the NT03+M does with an ET+30, but wasn't sure if the shape of the RS05RR would prevent that fitment. I already have extended studs, so using a 5mm spacer isn't out of the question, but wanted to see if anyone suspects I would have caliper clearance issues. Want to run the 18x10.5 +35 square with 285/35r18 for track days primarily. I'm on stock suspension currently (planning and doing FA500 true type +SPL arms and whatnot eventually).

I am considering sticking with the NT03+M since a lot of track guys are running it and I think both wheels look good, but the RS05RR did catch my eye. Appreciate the responses.

There’s no reason to go with that conservative a size.

You want 18x10.5 or 11, +15 all around. This is the range track folks use here, with anywhere from a 275 to a 315

+35 is worse than stock

Yeah, I was thinking 10.5, or are you saying that’s too conservative? The ET (30 for Nt03+m and 35 for RS05RR) is so I can run the same wheel front and back to increase the life I get out of the tires. Going to run a 20mm spacer in the rear, none in the front. Others seem to have run a 15-20mm spacer without issue (I believe Hotrodz runs/ran a similar setup).

I realize that’s suboptimal in a certain sense, but the ability to rotate the wheels is important to me. My real concern was the wheel shape of the RS05RR and if it would have any fitment issues. I would guess not, or to run a 5mm spacer in front along with 20mm in the rear (based off the offset of +35 that I was able to find in stock).

I have both the wheels you are considering. The RRs in 18x11 +15 and the NT03s in 18x10.5 +30. I run a 15mm spacer in the rear. Regardless both sets fit with sport brakes w/o spacers.

Awesome, thanks so much for the answer!! My wallet is less thankful. :tup:

I'm going to make two statements:
1. I used the search function. Although there were some SIMILAR specs, it wasn't exact.
2. I really tried researching on multiple forums and talking to multiple vendors because I wanted to figure this out on my own, but I just want to make sure before pulling the trigger.

Additional Info:
I have a 2015 Nismo.
I am installing Swift Spec R lowering springs.
I plan on using OEM Nismo tires, but I can change this if recommended.

Will this fit? I'm going for a flush look:
F 19x9.5 +22
R 19x11 +19

I'm mainly concerned about the rear specs. 10.5 isn't an option and the vendor can't do anything "less" than +19. These are custom wheels. I REALLY appreciate the feedback in advance.

I run an 11.5 rear with +30 backspacing. Not sure what you have will work or not.

Your goals are in conflict. You want a flush look. You are willing to pay, presumably, thousands for “customs” wheels (which don’t see very custom, if they can’t do better than 11 in width and +19

But:
- swift springs only
- wheel selection that appears to have very limited sizing

Why don’t you tell us what wheel you’re looking at? I assume I will then tell you to pick a different wheel, but hey, let’s find out

If you want to be flush, you need:
- coilovers
- SPL stuff
- rolled fenders
- better wheels
- a good alignment shop

If you haven’t already, read THIS:
http://www.the370z.com/wheels-tires/...tart-here.html

Having said all that, you sizes will work, they’ll fit, but it’s a fairly standard, conservative fit. If all you want is that low effort fitment, go for it

But if you’re paying for “custom” spec wheels, it seems like you’re lighting mo day on fire. It’s like paying for a tailor to do a special order suit, but in the wrong size

I've read your responses on this thread and was wondering if you would respond to my post because I figured I needed to prepare myself LOL I know some people have an issue with the way you communicate, but I appreciate the incite you provide.
Anyways, I agree with most of what you said and I should probably rephrase what I want. I said flush, but really all I want is to lower the car by about 1 inch and install wheels/tires that are aligned with the fender; not too far in, not too far out. I'm not expecting (nor do I want) my wheel wells to be nonexistent, I just want them to be reduced; hence the lowering springs. I suppose you're right in that I'm not going all out with the coil over setup and all the associated components with that, however, I'm just trying to make a tasteful mod w/o going overboard within personal reason. Of course, tasteful mods are subjective. You made a good point in the custom factor. I was able to talk to the engineer, and what I was told was the way the wheel is made the lowest offset they can shave the mounting pad to is +19mm. I can't argue with that; hence my post on this forum. I have no problem sharing the wheel - Momo Anzios. They look very different and I haven't really seen many wheels like this, especially on Zs. I wouldn't say they are crazy expensive, if anything, they are less than some of the very common wheels I've been seeing on Zs (probably for good reason). Just looking for confirmation, that is all. Thanks, again!

Way too busy a design for a stock body 370z on a mild drop. But it’s your money

Out of curiosity, do you think the same about the Rohana RFX11?

Same thing

You need to be running TE37's like every other Z on the road. :rolleyes:

:rofl2: mmm no thanks.

He should just get ForgeLines. They'll made any spec he wants. :tup: The new carbons are :yum:

There aren’t that many smart Z owners
Just look at this thread

I just looked these up. Holy...now those are expensive lol. Some great options though!

Like I said originally, I value your input on this thread, but damn man you sound like you were born angry lol

I came from Zilvia

You got mine on order for Christmas :ugh2:

You won’t know weather or not you’ll have your kinda flush look (as different people have different flush opinions) unless your Z is currently at the ride height that you’re planning to be & your alignment is also where you want it………after this, all you have to do is measure how much further out/in on tire sidewalls or wheel lips….pending your “Flush Prefference”

Another thing to remember, the rear oem 285’s will be stretched a bit more on an 11 vs the 10.5’s.

Unsure what others have told you, haven’t read back much…..but OptionZero is pretty Sharp in this field :iagree:

Appreciate the input. I understand the wheels will be slightly stretched due to the extra width. I'll probably look into get getting new wheels once they wear out. Like you mentioned about not really knowing, that's part of the issue because I'm totally stock right now. If the rear is tucking into the fender a little I won't be too worried because I believe that can be fixed with spacers and/or some other suspension components. However, if they are sticking out significantly (a little I don't mind), then I'm not sure how I'd correct that. Although Option doesn't like what I'm doing, he said it'll work, so that's all I really wanted to hear. The more opinions/input/constructive criticism, the better! At least for me.

just a suggestion...gram lights 18x10.5 et 12 are 1800 shipped to your door

i personally picked up a set yesterday

Those are nice wheels, but I wanted something a little different. Aftermarket wheels for Zs is a lot harder than I thought! Plus, I want to stay at 19. Thanks!
