15x9 6UL
You guys are probably geting tired of me chasing you all over the interweb and advertising the same old tired *** 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

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
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!

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

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

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?
