15x9 6UL
 

You guys are probably geting tired of me chasing you all over the interweb and advertising the same old tired ass wheels. So to keep the streak alive..

Most of you in the market for maximum grip hardware know about the 15x9 6UL in production and probably ordered yours already. In case you don't know, here's the rundown.

Scheduled ship date is early April, 2008, taking orders now

* 15x9 +36, 6.3" backside setting
* 4x100
* Target weight is 14.3 but CAD model shows 14.0 currently
* Full nickel painted, silver or black with machined lip
* Clears Wilwood BBK’s and factory Sport brakes. Some 11.75 rotors clear depending on caliper and offset. Templates here cutout - dwg
* Custom offsets, colors and bolt patterns, not available
* Quantity shown on website is what will be available from current run when they arrive in April (many have been pre ordered).
* Pricing on the website
* Totally get like 2psi more boost

If you are wondering about fitment READ THIS!

15x9’s on a Miata are DIY fitment, absolutely not plug and play. I will not be able to tell you precisely what needs to be done on every individual car. I can tell you that they will fit with fender massaging and if lowered at all, liner trimming/removal. Basically, you’ll have to make a little room for them. Fitment on cars other than Miatas is unknown but it's safe to say that a sawzall might be in the picture.

Unflared Miatas with 225/45’s or larger will mean rolling fenders. NA’s may require slight pulling (stretching) the fenders front and rear. 205’s and a little camber might fit without any mods at all. The 275/35 Hoosier will need serious rolling and pulling and may still rub a little depending on your camber and bump travel. If you order the 15x9 6UL's, I assume you are willing to get creative, massage the car a little to solve any clearance issues that may arise.

For those of you with flares, yes of course you will probably want spacers since these essentially fit the unflared fender.

Cool java graphic for comparing different wheel, tires and offsets

This is a limited production wheel but I will keep spares in stock after they sell out. If there is a future production run of the 15x9 6UL, it would likely be first qtr 2009.

I do not offer tires or mounting but here are some recommended sizes:

205/50/15 (drift) common
225/45/15 RS2, R1R, R888, RA1, A6/R6
225/50/15 RS2, RA1, V710, A6/R6, common
235/50/15 R888
245/40/15 CR500
275/35/15 A6/R6

Hankook RS2, Toyo R1R, Toyo R888, Toyo RA1, Hoosier A6/R6, Nitto NT01, Kumho V710, Avon CR500, common

Picture is a 15x8 6UL with 1.125" lip. 15x9 6UL will be virtually identical but with a 1.7" lip

damn only if you guys had better off set..... wheels look realy nice.

What do you consider a better offset?

Better?

someone likes his sportmax... :rolleyes:


if only there was a street tire in a 245 width. I mean the CR500 has "tread", but is it streetable?

Not really, DOT though. The closest thing to the CR500 is maybe an A6/R6. Very thin, not much in the way of puncture resistance. Dimensionally, the CR500 is short too, 22.6 IIRC. Take a look at 225/50/15's. I used to be of the school that 225/50's were too tall. But you can still get suprising bump travel and general clearance even on an NA once you pull the liners out and roll. The 225/50 V710's I ran for a while on few cars, needed a wider wheel. There was definitely a little of the car rolling over from decrease in sidewall support but mechanical grip was higher, braking in particular.

I'll have to see if I have some pics of the NA with 225/50's on the 8's

Maybe this individual is upset because he does not feel like purchasing wheels+spacers to fill his flares. Probably not likely but i dunno :dunno:
I think that is one of the main reasons I am shying away from these wheels. I like the wheels a lot, but if your implying I need to spend another 150 bucks in addition to the 900 for 4 of these.. that gets a little steep.

Just added a link to the OP to a good online tire/wheel size comparator.

I didn't build the 6UL's specifically for flares for 2 reasons:

1. Flares don't intrinsically make my car faster
2. The ratio of Miata owners that have or are willing to do flares to those that aren't is maybe 500:1

In any case, if you have flares, I'm guessing the final look is more important than the additional tire scrub and aero drag so spacers maybe are OK? From what I can tell about 1/4 of all the 15x9's ordered so far are going onto flared cars with spacers so apparently some people are OK with it. A bunch of other users are shoehorning the 275 Hoosier under heavily pulled stock fenders for CSP. The casting is weight/strength optimized for the minimum possible track width. You then tune with spacers just like virtually every Spec Miata and most club racers in other classes.

Ultimately though, I'm selfish. ;) I build the wheels to the spec I need for my track setup and race tires.

The 15x9 6UL is designed to fit under the massaged fenders of a Miata. It's not like I don't understand how to design a wheel with the right offset for flares. I simply chose not to. But that won't keep the guys with flares from seeing it from their point of view, sorry!

QMax
 

Hey Emilio, welcome to mt.net :) let me take this opportunity to ask you whether you have any news about the release of your Qmax coolant reroute system. I'm facing heat issues with my engine and I'm anxiously waiting for it.

Best regards,

Rafa

Fair enough explanation

Nothing new to report yet. Looks like the first ones we'll take orders for are the 1.6 and 1.8 race (non EGR) systems. EGR and the FFS versions will follow in a few weeks. First production run might sell out as there is a large Miata vendor that wants them too. If you haven't already contact Steve to get on the short list.

Here's a start:
http://www.949Racing.com/server/superstreetmagazine.JPG
http://www.949racing.com/ProductImages/GRM_cover.bmp

The guy in the red Civic is on his third magazine photo shoot with the wheels and is sporting a windshield banner now. So basically; win a few national level races, get a few hundred thousand people to see my wheels on a website homepage, in a magazine or on the cover and we'll go from there.

As many Miatas as there are out there with them I'm still waiting for coverage on that first big win on the 6UL's.

Be careful though, no actual racing & too many stickers = rice :nono:

15X9=the sexxx
i will own these, one day...

well i dont run flares and my car is not for looks.. ill prob have one of the better set ups and higher hp's than most people on the site... and i just like my wheels flush with fender. ive seen your wheels in person i think there great looking wheels i just wish they had a better off set.....

thats my 2 cents

I'm glad you like the look of the wheel. The offset and backside setting are perfect for what they were designed for and couldn't possibly be "better" though. If I told everyone that they were perfect for flares, I agree they could most definitely be better. As it is I let everyone know my design goals and what to expect.

I tried my damndest and spent a lot of time trying to make a 15x10 6UL for flares. Advertised for 11 months. In the end I couldn't sell enough in the pilot run to pay for the tooling and threw in the towel once and for all. So the 15x9 is a no compromise wheel for Miatas without flares.

Got any pics, in car videos, info on your car setup? I see you have Stance coilovers. So Florida. You must know Fyrestrike and Soflarick. What kind of lap times at Homestead and Sebring?

Rota WHAT? ;)
BTW, these 8" ULs only weigh ~12lbs each.

damnn that's nice!!! no rubs? and what size tires did u use? you guys are making me change my mind about the getting the RB's

I run 205/50r15 Falken Azeni RT-615s. You can run 225/45r15s all day long on them including RA-1s, RS2s, NT01s and maybe a few others. You can also run 225/50r15s for a taller tire. If you really wanted to you could run 245s as well, i just can't afford them.

205-50-15, no issues

I think the 15X9 UL with the new Toyo R888 235/50/15 with some rolling and those "flares" will look fantastik, and that's what I'm gonna do:)

BTW those flares are those that are sold by http://rev9autosport.com/shop/products.php

Emilio, do you think that will work? (NA)
Thanks

Good idea.

:D

I want...BAD!!!
Emilio, I want two sets as soon as I can afford them. Do you plan to keep these in stock or is this gonna be limited production. I hope I don't miss out as I am knee deep into my motor and turbo builds and cannot afford to buy these anytime soon.

They are limited production in the sense that they sell out as fast as I can make them.

They be fitting
 

BellWilliam is officially the first guy to get a set on the road and he was nice enough to let me drive it first. Full tread 225/45/15 NT01.

So..... No rubbing. Anywhere. At all. We chucked it around the local business parks, bashed through a driveway at about 40mph, full lock donuts on bumpy pavement with a passenger. That's an NB with 9/6 Flex at about 12.6", -2° camber and a very slight roll at the front edge of the front fender lip only. 100% stock rear, full liners all the way around.

To tell you the truth, William and I were a bit dissapointed. We both expected to have to drag the Eastwood out for him to get home.

So I'm revising the fitment guide. NB with 225/45's fit about the same as the 15x8.

I'm so bummed now. If only i had waited a year I could be rolling on 15x9s.

You're looking at it the wrong way. You probably got your 8's at the old price. When I am out, resale is, um good. You simply rented a set for about $15/month.

lol, nice.

Well this sucks since my 15x8's (for my NB) are supposed to ship within a few days.

What is wrong with all you guys, I would love to have even the 15x8...I may take that 0% CC offer I got last night...my anus will hurt but I want these bad.

http://www.949Racing.com/15x9/15x9_6UL_275_wt.jpg
Rear
The 275 has about 5/8" clearance to the inner fender in rear, right under the outer lip. Might work with a pull.

Front
A little past the lip with about 2.4° camber. Clears a 2.5" coil straight ahead. Tire hits the spring at full lock either way. Rubs the brake line at full lock but that's an easy fix. Cleared the pinch weld behind the tire with room to spare.
http://www.949Racing.com/15x9/15x9_275_NA_F_6.JPG

I am fucking DROOLING over here. How much effort are we talking about to get them under stock fenders?

For the 275's, dunno yet.

HEY GUYS.
Just wanna start off by saying The 6UL's rule. i have a set of 15x8 matched with 225 45 nitto nt-01 and so far i've had 3 of 7 FTD's on them at local autoX. now i need a second set but i need the 15x9's. running out of funds, is there anybody who has a used set that wants to sell them??? i'm going to mount a set of goodyear full racing slicks on them so i can get FTD everywhere!!!

Did you really just ask if someone has some of the brand spanking new 15x9s for sale in used form? Not sure what kind of idiot would sell his new rims that he just received or hasn't received yet but you won't be seeing any used ones for sale anytime soon i bet.

275 on the NA
 

275 A6

These will require a flat roll front and rear. Pull maybe 1/2" in front and 1/4~1/2" in rear. This car doesn't have much camber so it's conceivable that they might just squeak in with the less pulling with maybe -2.5° fron and -2° rear. As on the non-running NA I first checked, the tires hit the control arms at full lock. Bombing around a few business park cul-de-sac's I couldn't use enough lock for them to rub though so I don't think it'll be an issue expect for parking. You either have the choice of running a 3~5mm spacer up front and trimming the fender or just watching how much lock you use when rolling through the pits. I'll set mine up with no spacers.

..and omigod does the car turn. It's like having downforce at 45mph.

275's = pure sex.

Makes me feel better about the excessive flaring now.

275 on the NB
 

275 A6

The NB was a much easier fit. With slightly rolled fenders, no pull and not enough camber, we got them to clear with just the very slightest rubbing at very high steering angle bashing through a driveway. Basically, they clear just fine.

I think an NB with the right amount of camber will clear the 275 / 15x9 6UL with just rolling. The tires hit the 70mm (2.75") spring perches at full lock just like on the NA. Those with 2.5" or 2.25" race coils will have more room. When the XIDA are ready in a few weeks I'll be able to check clearance with 2.25" coils myself.

My head is just spinning right now. I cannot believe these fit under massaged stock fenders. Cannot believe it.

I must have them. Emilio, what does your production schedule look like for 15x9s in the fall, let's say around October? I am calculating $2k for 275/35 R6 Hoosiers and 15x9s, with leeway for price increases, tax, shipping, and mounting/balancing.

Nothing on the table for the fall yet. I'm sure there will be something in the works. And yes, all 6UL's wil be going up about 10%.

I love starting sentences with a preposition. Just makes me feel good.

I'm guessing this is a "Buyem and tryem and if they don't fit, I'll buy them from you cheaper" posting:giggle:

That NB makes me want those so bad. Too bad I can't afford 275 A6s.

Thanks for posting all these specs Emilio, I want these even more now.

Also, what is the ride height on the NA these were fitted on, it appears a bit taller than my car, so that will change a few things for me I am sure.

Ralph's SM2 ride. Rolled and pulled.

:bowrofl:

What is the process for pulling fenders?

It's a shame there's no streetable (RA-1 ish) wide tire for these. I could use all the rubber I can fit in the back.

Frank

RA1's come in a 225/50 and are perfect.

FMowry is going monster miata on us, he wants 275s i'm sure.

The 275's are hardly streetable though. The 225/50 RA1 is wider than the 225/45 and makes a great street tire for a high hp weekend street toy.

275 ft-lbs at 2000 rpm > 225-anything tires. I've got the 225-45s RA1s. I doubt the 50s would make much of a difference.

Frank

I think the 235/50/15 R888 might be the answer for the big HP streetable cars.

I think I will go with a set in the next few years when I retire the miata from dd duty, unless of course a nice 245-275 comes out with more then 40 treadwear.

What would be the main reason for an NA bodystyle owner to go 15x9 over 15x8 if you are still using a 225/45/15 tire?

Plan is to get the SE Flex and 6uls from 949 in July.

Thanks

I am curious too.

Also what were the details on getting the 15x9's + 225/45/15 tires to fit on the NA?
