My first setup with brakes will be my current wheels with whatever spacer I need, if any. I'll make a template and send it to my friends at Tire Rack to see what wheels they have that fit (which will include this one by then). Unfortunately, Emilio's template doesn't come close to clearing my caliper/rotor combo, so 9s are out.
My idea of the ultimate Miata brake setup would cost more than $2000, using parts from Wilwood, Hawk, PFC, Earl's, plus some custom bits I'd have to get made, and would be challenging for wheel fit. Everything less than that is a compromise for lower cost. But I believe that what I'm doing will have lower initial cost than a Wilwood kit, as well as lower replacement parts cost, and deliver better performance.

I have cracked Corrado rotors on dynalight setups, even cracked rear rotors before, even killed new pads in a single day at the track. the setup I have now lasts many track days on the same set of pads.
Having said that If I wanted to be fast I would ditch my brake setup to fit 9” wheels instead of 8” if I had to. The 9” are that much better. I tried them back to back and was significantly faster by more than a second on the 9” with the virtually identically worn 225 RA-1’s

That makes me really want to invest in brakes right there. It probably wouldn't take much time to add up the money spent on cracked rotors and burnt up pads to justify your investment. I'll likely be copying your setup someday. Most probably the next thing I do after upgrading my suspension/chassis rigidity. Not increasing my power any more until I have better brakes...

So far, Enkei USA does not know what the wheels weigh. Their tack is to wait until the wheel actually arrive at the end of January so they can be weighed here. Enkei's marketing material states a goal of being lighter than the small inner diameter (~13") design RPF1 but that is impossible with a full inner diameter PF01. I'm guessing the 15x8 PF01 will weigh about what a 6UL weighs or a bit heavier, have similar brake clearance and cost about $50 more.
For our own 15x7 and 15x7.5 6UL in development, we have followed Enkei's idea of reducing brake clearance to lighten the wheel. My reasoning is that anybody that is truly running out brakes with a 15x7, should be running 15x8's or 15x9's anyway. So the bigger sizes get the BBK room.
As Bob mentioned, there is plenty of brake clearance with a 6UL. We designed that in from the beginning.
15x8 6UL will clear a Wilwood Dynalite 4 piston on an 11" rotor (Goodwin BBK)
15x9 6UL will clear a Wilwood Dynapro 6 piston on an 11.75" rotor (V8R BBK)
Bob's DP6/11.75" set up is a modified Mini set up IIRC, a bit more offset than the V8R probably.
As Modernbeat mentions, that refers to the RPF1, not this new PF01

I just went to your site to see if anything had changed, and it didn't appear to be any different. What you posted above suggests you're going to have different profiles in some new products. What's up?

Because Wilwood is kind of a standard in the markets your wheels serve, you designed for them, and excluded your product from being used by someone who wants to do better than typical Wilwood apps on brakes. At least that's the way I see it. I seem to be the only one with that opinion, though.
I designed the wheel to fit the largest existing Miata big brake kits that actually work, in this case the Goodwin BBK. The MPCA (Winner Pro), Baer, Brembo, Ksport kits for the Miata are all basically oversizes, underfunctioning street bling so I ignored them. Since then, some of us have found that the fastest Miatas do actually need 11.75 rotors and 6 pot calipers, so you can run spacers with 8's on a Miata or 9's without spacers. I have no plans to design a wheel around OEM cast steel calipers on oversize low offset rotors for the Miata, sorry.
Regarding the narrower wheels, they just need to be light, they don't need the same brake clearance as the 8's. The guys that complain the 7's won't clear BBK's should be running 8's if they are genuinely in need of more braking. The remaning 99% of 15x7 buyers just want the lightest wheel that will fit their stock brakes.

Lots of 6UL jealousy in here. You peasants need to get wheels and be a man for the first time in your life. Now please excuse my while I spread Beluga caviar over my California Condor scrambled eggs and Brioche.

Number of pistons doesn't really affect wheel fit. Wilwood calipers tend to be pretty thin in section, with short pistons, thin pads and no dust boots. I'm planning an OE caliper with thicker pads, dust boots, and a thicker cross section for greater stiffness. Probably a 282mm rotor, a little smaller than 11.75 in., but thicker and lower-cost. It'll be cool.
Thin pads and short pistons ,go hand in hand.
What OE caliper? Hopefully something AL :P

What OE caliper? Hopefully a Brembo atleast...
Just to note, Nissan kicked Brembo to the curb for the latest round of Z/G four-piston calipers. Nissin, Sumitomo and Akebono all make nice OE stuff.
The Brembo race stuff is nice, but too expensive for a Miata.
My stuff will be cheap x good. And yes, I'm keeping it to myself until it's running.

I want to take a moment to let you guys know that all your stuff sucks and you're **** so I'm going to make something 10x better...but it's super secret so I can't talk about it. I also have a pretty sweet trophy rack that not only blows away your rack, but your mothers sit on one shelf, well their likenesses from a few years ago before the slampigs turned into leather bags.

That's what I suspected as well, but he's not posting from Dade county (or anywhere near it).
Uncanny resemblance, though.![](https://www.miataturbo.net/images/smilies/rolleyes.gif)
Gotta wonder how many lead-acid batteries he's got stuffed into this EV conversion of his that none of the traditional big-brake kits are adequate...

I wasn't sure if this was what I thought it was. Bravo.
I've never been a big fan of solving problems that don't exist. You can design the best brakes in the world, but if you know anything about brakes (and I presume you do) then you also know that they don't make race cars faster. If your brakes are better than the current crop, but they don't fit under the best wheel and tire package, then it's an exercise in futility.
Regardless, I look forward to seeing what you produce, even if there's no reasonable application for it.
