Looks like preload is adjusted by the end-user, unlike with the ball-bearing cartridge in the MiataHubs.
They also seem to be using long socket-head cap screws threaded in from the back as wheel studs. Interesting choice, given how many thread-in wheel studs are on the market for European cars.

Wilwood's forged aluminum ProHub Kit for the 1990-2005 Mazda MX-5 Miata provides a lightweight and fully user-serviceable option, with measurably increased strength and durability over aftermarket OE-type steel replacement hubs.The innovative ProHub design is a direct bolt-on and accommodates any brake package configured for the stock spindle and hub. ProHubs eliminate the one-piece, sealed ball hub bearing design. A uniquely designed spindle collar and lock-nut system incorporates separate and wider spaced inner and outer tapered roller bearings for added hub support and increased load carrying capacity. Regular bearing lubrication and maintenance is simplified, while providing fully manual and infinite adjustment to the bearing preload.

One thing that bothers me, while they don't actually state it. It doesn't look like there are replaceable outer races from the pictures. So if you don't preload it enough and trash a bearing, do you need a whole new hub for 349.50?
Maybe they can be knocked out upon closer examination, but it is hard to tell, and the diagram doesn't show it separated.

I have zero interest in being a guinea pig, he only has like 25 hours on his test pair and someone has already had a failure that sounded like it was almost right away, for the time and peace of mind I'd rather have something that's proven

I didn't mean to suggest that the outer races were aluminum, just that there doesn't look to be a provision to knock them out with a drift. That and the lack of outer races in the exploded view diagram make me skeptical. The pictures aren't great tho

Those look interesting but I'm skeptical as well, just because they work on an e30 doesn't mean they will work for our completely different geometry/loadings/angles/etc plus the studs leave a lot to be desired

Dunno why you deleted your post.

To be fair, that was one of the poverty/economy bearings he offers. Unlikely to have that issue with the higher end bearings which he also offers. Not a very good reason to write off the E30 option. Definitely still needs more testing, though.

That's fair, he is offering them for testing and not as a vetted out solution.
Too bad you need to have a replacement one modified so it's not super convenient either
I guess we'll just see how things shake out

Anyone tried these yet? Half the price of the Miatahubs.com hubs. What's wrong with having to adjust preload? Are people afraid of dial indicators?
I have a spare set of Centric premiums but I have a hard time replacing the OEM units currently on the car with something "lesser".

I don't think the problem is adjusting the preload, its just that some have experienced (on other taper roller bearing offerings) a loss of that preload in a short amount of time.

The loss of preload in older hub designs was due to the nyt backing off. The v8r design in the picture wont back off.
Set you preload. And make packing and adjusting part of you maintenance cycle. It will last a long long time.

i saw the wilwood hubs the other day while looking through their website. i am thinking of giving them a try. i am ok with adjusting preload. every airplane i have worked on uses tapered roller bearings and preload is adjusted with every wheel and tire change. we are talking about a machine that weighs about 100,000 lbs hitting the ground at 120mph when landing. so i do not find the idea of adjusting preload a detriment to the unit.

Has everyone seen this yet?
Hello,
We are reaching out regarding the Miata hubs 140-15725 that you had purchased through Jegs. We would like to arrange to have those returned/exchanged for an updated/re-engineered piece which is much stronger than the original. Please get in touch with me to arrange an RMA and UPS return label.
