So the driver side front hub went out at auto-x this past weekend. Need a new hub before the next event in two weeks.

Which one from rockauto is the best choice?

Whatever one you get, grab at least one more. Miata hubs aren't lasting as long as they used to, and if one went the, other probably isn't far behind.

Seem to recall Keith touting the benefits of what FM is selling. Might be worth hearing the sales pitch?

Looks like it may not make the next event then due to my budget constraints.

There are lots and lots of opinions on this topic. SKF or Timken (both have NTN bearings) seem to get semi-reasonable feedback.

If money is very, very tight, I have to imagine that for autoX you could get through a session with the $28 rock auto option and then keep it as a spare when you can afford to replace it with a decent one.

For Spec Miata use, I usually get them from Mazda Motorsports or Advanced Autosports https://www.advanced-autosports.com/collections/suspension-steering/products/front-wheel-bearing-90-05-miata

You can blueprint them and swap out the grease, that seems to help a lot. We sell a blueprinted hub, but there are DIY guides online if you want to try it. No guarantee that they were written by anyone who has any sort of clue, though. https://www.flyinmiata.com/na-nb-blueprinted-front-hubs.html

We're working on a roller bearing front hub that should stop the problem once and for all. They're still in initial testing, but the FEA is really promising.

Any idea on a timeframe? May just buy the Timken option for now if they are coming soonish.

I'm not sure of the production timeline. By next race season for sure.

I don't have that handy. More than the cheapest stuff RA sells, but competitive with OE. Especially given the lifespan.
