Default Miata Track Hubs: Custom design

Let's talk Miata front hubs: For me, I clean and repack my old style OEM ones every ~30hours and every weekend in the rain on street tires. I know others do this more often to avoid a failure. I am working with Hoosier Performance Engineering (HPE) to come up with an acceptable bearing design (likely tapered roller) to get away from the failure when you laterally load the OEM ball bearing design. Options on the market today include "Blueprinted" hubs but they don't address the Achilles heal of the bearing design. HPE has a successful F-body hub on the market today and they are trying to gauge interest in a Miata hub that would be designed for an infinite life cycle under track conditions. Who would be interested and would you be willing to pay as much as $350 per hub for something like this? What is your application?





For reference, Flyin Miata charges $212 + s/h for each of their blueprinted hubs with ARP studs https://www.flyinmiata.com/na-nb-blu...ront-hubs.html

We are one of those teams that repack the hubs between each race weekend (so every 14 hours or so). Talk with Jeremy, I know he's done a lot of research on bearings and different types, he maybe able to help you out some. If you need his contact, shoot me a message.

I would buy these just because. All four corners. I just like the sound of reliability.

I am interested. Usage will be ~10 autox events on hoosiers, and ~10 track days on probably 245 RC1's.

I'd be interested in a set eventually. Still need to do a lot of cutting to figure out how to fit the 15x11 6ULs that showed up yesterday. If you could offer something that was bombproof and never needed attention, I'm sure you'd have some market for it.

I'd be more interested at like $350-400 an axle.

Question: Who cares about retaining ABS? The bearing package they are trying to put in there means that we most likely will not be able to retain the tone ring for the sensor. You might be able to move the sensor or do some thing else but that's not in scope here.

Likely not a problem since the 01+ and Mazdaspeed are the only NA/NB with ABS worth anything anyhow.

I want to keep abs. I didn't spend nearly a grand in used parts and ~10hrs to add it to an non abs car for no reason. And for Autox with big fat sticky Hoosiers (and a **** ton of money in the tires) no one wants square tires. TNTUBA and Leafy would agree.

Not sure what you mean about msm', but any 01+ car with ABS, or anything swapped is worth it.

The rings are the same across all model years, I'm using '04 abs brick in a '94 chassis.

I wasn't anticipating the love for ABS, it's not used on the track since the early ABS system wasn't the greatest plus it's not a common option on the early cars. What other markets besides Auto-X use ABS and wouldn't appreciate us removing the tone ring?

ABS ring, yes. If not included on it, at least a way to press on the tone ring from a standard Miata hub on. The tone ring can be pressed off the OEM hubs. We do it all the time because we use a front ABS sensor to feed our AIM dash.

As long as it stays the same size you can just put a tone ring on.

That's the issue here, the small OEM housing is restricting what they can do in terms of offering an alternative bearing package. If it has to be ABS capable it makes things really tough, more to come

If you can just machine the teeth into the housing you get a little wiggle room. Especially if the sensor can be spaced out.
