Emilio,

I have a question. I spoke with a couple Spec Miata racers last weekend that run your old Spec Miata Version of the 6UL. They all seemed to say the same thing, they are made in China and they bend easily.

Any chance the 6UL GenII has corrected this concern?

 

275's rub OEM springs. Wheels may contact control arms. 15x8's are PnP.

The discontinued 15x7 6UL for Spec Miata, nor any wheel I have offered, are not made in China. I have not had any reports of them bending easily but have gotten reports of them holding up well even in crashes and car to car contact. In two cases I've personaly seen, paint of the other car was on the rim and the wheel was still perfectly straight. In another case, a guy got hit hard enough to bend the rear lower control arm and the wheel was straight.

So there isn't a "concern" that I'm aware of. The low pressure cast T6 heat treated gen II 6UL is even stronger, with better fatigue life and failure mode behavior than the gravity cast T4 heat treated gen I 6UL it replaces. I have no plans for a Spec Miata version currently.

 

I'm not interested in a Spec Miata version, but since a few of the guys were running them this weekend I was curious as to how they compared durability wise to the Team Dynamics wheels I and many of the other racers have run.

I am building a EP Type car that I was planning on running the 15x9 6ULII wheels. Where are the wheels manufactured?

 

One of mine is hitting, any recommendations (small spacer perhaps) to avoid this?

 

6UL FAQS & FITMENT INFO

Taiwan. Are you asking me how a gen II 6UL compares to a TD in "durability"? Not sure which aspect of "durability" you refer to but in any case, the only accurate answer would come from back to back test data, which I doubt anyone has. Additionally, TD does not manufacture a wheel that is directly comparable in width, offset or weight to any 6UL variant so a direct comparison is impossible.

The general answer is that there are several thousand Gen I 6UL's running around and the consensus seems to be that they are stout, particularly considering they're weight and relatively low cost.

 

I was comparing the 6UL Gen I 15x7 to the Team Dynamics Pro Race 1.2 15x7 Wheel. Weights are the same, and I was simply asking due to the concerns that the racers expressed. Several of them stated that track ruts and riding curbs seemed to bend the 6ULs more frequently than the TD wheels.

Please don't take this wrong, i'm simply stating to you what I was told by some of your customers so that I can make a decision about purchasing some of your wheels for a different application. I am glad there is someone making wheels in sizes and offsets the miata community actually wants!

 

My scale shows an average of 14.4 lbs for a few samples of the 2.0 and around 14.0 lbs for the 1.2 samples I've weighed. The discontinued 6UL in that size averaged 13.05 lbs. There is a reason the runoffs winner was on 6UL's

The 1.3's are a bit lighter, averaging about 13.6 lbs for the samples I weighed. Haven't gotten any of the new Chinese made 1.3's but Goodwin tells me they're about the same as the UK made ones.

 

Just wanted to update whoever might be interested. Final production weights on the Gen II 6UL due in about a month are as follows:

12.8 lbs Discontinued gen I 6UL 15x8
12.3 lbs Gen II 6UL 15x8

13.2 lbs Discontinued gen I 6UL 15x9
12.55 lbs Gen II 6UL 15x9

The new wheels are stiffer, stronger with a better failure mode (they bend further before breaking in destructive testing).

Discontinued 6UL was gravity cast, T4 heat treated
Gen II 6UL is low pressure cast, T6 heat treated

The Gen II was completely re-engineered from scratch to take advantage of the new manufacturing process. Very difficult to to tell them apart other than the new smaller cap and "6UL" now embossed on near the lip.

 

Emilio, are these going to be limited production and if so how many do you expect to produce (Matte Bronze)?? Will there be any other runs later in the year? Just asking because I'd like to pick up a set, but am strapped at the moment....but if I absolutely had to, I could suck it up and gettem now but I prefer not to... Let me know when you get a chance!

 

any ball-park ETA?

Thanks.

 

Inspiration! Non-stick! Teflon pan coating on wheels! No more brake dust issues. Hose it off and go. Holds up to heat too. Goofy? Maybe. Useful? Sure. Could be the next big thing.

 

I too am in the same situation... Let me know.

 

Regular production item. Check the homepage of the website or item page for production info.

 

Noticed you guys have a non rendered pic of the black wheels up. Any idea when you guys are going to start shipping out?

New info, website gets the update. Significant news, those that have orders in get the email. Always check the website

Currently, wheels are in production. MX5Centre (Australia), will have wheels before the end of May. US shipment arrive here first week of June-ish.

From here on out, I won't respond to questions about ETA. You all have to go to the website just like everyone else.

 

FWIW, I have been watching the "qty available" on the 15x8 bronze lately. It hovered around 60 for a long time. Checked today and it was down to 16 so I got on it and bought a set today. Only 12 left! If you are on the fence, better get moving! 15x8 Nickel are already out of stock!

 

The wheels are on their way to me today. If you have any question about your order, send an email or call.

Woo Hoo! Got my RS3's already and they are lonely. They need to mate. Hope to see mine soon.

 

I haz 2 sets in the mail!!!
