New hubs for Spec Miata and other Miata race cars add life and are rebuildable
Part No.: 0000-04-5HUB-ST
Racer Price: $379.00
The front hubs on a Spec Miata take a beating. SM racers know that the hubs need close monitoring and frequent replacement, and that even the heavy-duty hubs will sometimes only last 10 races. And when a hub fails, the consequences can be severe â€“ a lost wheel that at best results in undercarriage and suspension damage, or a meeting with the wall at worst.
STM Powersports, owned by Spec Miata racer Mark Beyer, has come up with a solution that is sold through Mazda Motorsports and approved by the SCCA Club Racing Board and NASA for Spec Miata, and can also be used in other classes (as allowed by the rules) where NA and NB Miatas compete.
â€œWe utilize a tapered roller bearing on the hub,â€ explains Beyer. â€œThe roller bearing has a lot more contact surface than the ball bearings used [on the OEM hub].â€
Beyer tested the hubs last year and had them on two cars at the NASA 25 Hours of Thunderhill, where they lasted for the duration of the race. But not only are they durable, perhaps the best part is they are not a use-them-up-and-toss-them item â€“ you can rebuild them.
â€œYou can take them apart and put new bearings in them,â€ he says. â€œTheyâ€™re the same offset, same everything as stock.â€
Beyer says the hubs should last 20 hours at a minimum, which is much more than racers usually get out of the stock units. And, like everything else STM Powersports builds, theyâ€™re made in the U.S. in Southeast Michigan.
