I have no experience with these, but both the picture and the parts list indicate that the $699.99 kit is for two front hubs.

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.
So nobody else needs to guess what is on the linked page.

Preload adjustment and hassle just like the MAZDASPEED COMP/STM hubs... Hard pass.

Agree; IMO the BMW hub's recently developed are a strong, reasonably priced fix that looks to be the prayed for end to the issue.

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.

It is highly unlikely that the outer races are machined in aluminum; therefore there should be a way to separate them as they got them in there somehow in the first place.

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

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

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.

Dunno why you deleted your post.

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
