MiataHubs
 

Hi All,
i was checking out their webpage. Look good. Anyone got feedback on these?
cheers

Buy them

Previously eating factory hubs in 1-2 days. We switched to Miatahubs just before COTA. They're exceptionally well made. They served us perfectly and came home with exactly zero play in the hubs. Looking forward to a nice long service interval, and when they are serviced the bearings are reasonably priced.

Which is amazing because COTA is notorious for absolutely slaughtering hubs due to basically every corner requiring use of the curbs. Hell, my buddy used to do a bunch of instructing at COTA and as such got a ton of laps there and had his axle snap off in the diff.

We tested one of the prototype Miatahubs for nearly a year. Held up in conditions that would kill a stock hub in less than one HPDE session. The production hubs are improved over the proto we tried unsuccessfully, to kill.
Not cheap but clearly the most robust hub option available for the NA/NB. Nothing else is even close actually.

I ran a prototype set of these hubs all last season and just recently got the final production hubs on my car to begin this season. On my V8 Miata (LS3, 15x11, 275 Hoosiers) I'd kill an OE Mazda bearing in about 10-20 laps (not kidding). I managed to log nearly 15 hours of track time with the prototype MiataHubs on the V8 car without a failure. I also have a BP4 powered Miata that I sprint and endurance race. I logged another 55 hours on the same set of hubs, swapping them between the two cars, for sprint and endurance races.

The final race of the season last year was a NASA sprint at NCM. I didn't feel like pulling the MiataHubs off the V8 car so I figured I might as well put all my OE Mazda hub inventory to use since it was becoming obsolete. I started that weekend with a fresh set of OE Mazda bearings (ST4 class, 225 Hoosiers)... and I had to replace the left front on Sunday before the final race of the weekend after about 2.5 hours of use. This all goes without even mentioning the hub flange failures we have experienced with OE bearings.

Hey I just saw your car I think at Harris Hill. I hate to derail this, but why do you think it's "required" to use curbs. This track is like 5 cars wide; it's pretty darn easy to stay within track limits and still be fast. I can see if your hell bent on 10/10 laptimes; but honestly is it worth the abuse? Now I'm not saying I never touch the curbs but it's maybe once per lap in S's and with a unloaded wheel so highly doubt i'll be experiencing hub failure (6 COTA track/instructing days so far).

I only run my car in TT, so yeah, I accept the abuse and use everything available. NASA track limits is the second white line so up T8 I'm completely inside the first white line with left (loaded) side on the curb for instance.

My buddy who snapped the axle doesn't know what mechanical sympathy is, so even at DE he's full tilt.

Well done jpreston!

Do these hubs help pad knockback? I know there are multiple areas of deflection but I expected the hubs to be the worst offender.

Yes, these hubs seem to eliminate all but the most extreme knockback. Savington just messaged me last weekend after running his first event with the hubs on his SPM S1 car, and said that the knockback he's been chasing for two years is finally gone. Aaron (cuonice) was experiencing unsafe levels of knockback with big aero and 275 hoosiers on his V8 car, so much so that he had parked the car until he could figure out a hub solution. My understanding is that his knockback problems are almost 100% gone now, with a very small amount still coming from (what I assume to be) spindle flex.

Thanks jpreston!

Something else to consider. If the hubs deflect enough to cause knockback imagine what they’re doing to your alignment specs!

Vegas also had knockback issues, about 85% resolved with the MiataHubs. Not very scientific but a massive improvement. I can do an entire sprint race without ever "setting" the pads with a left foot tap on the straights. I'll get a slightly different pedal maybe 2-3x per race. Where on OEM hubs it was pretty much half pedal every other turn requiring me to learn the NASCAR left foot thing on every straight. So spindle flex is only a very minor contributor to knockback in my opinion.

Yup. I had fully trained myself to set the pads with my left foot into every braking zone. Had to un-train that at CVR, since the pedal is now perfect. Knockback is always a little worse with worn pads so we'll see what happens when this set of pads wears down a bit further, but I have very high hopes.

Same here, we ran a prototype set last year. Put 50+ hours on them with zero problems and they are still tight as new. Just ran the endurance race at Barber and went head to head with cuonice for 2 days. We had some pretty good wheel to wheel contact with a couple of cars some and are in process of pulling them to check them out.

I would expect so with endurance type calipers when the pistons come out of the bore by a substantial amount. Pad shims work great for eliminating this. I think you’ll fight that regardless of how stiff the hub/spindle is.

Thanks for the the positive feedback! I can’t believe hubs like this finally exist.

Just bought these last week. Waiting for them to ship. Excited for a bulletproof front hub option.

Are there any good rear options other than the custom machining that sadFab does on the MR2-s rears?

A Chumpcar team just got dinged 20 pts for using these... Apparently the 2x rule doesn't count for hubs, they must be OEM. Hard to not argue it as a safety issue, but that is a slippery slope...

These look great, I wish we could run them in SM... It will probably be legal in a year or two.
