RX8 - NC Mazda MX5 Miata Front Hub upgrade
These are Genuine OEM Mazda Motorsports RX-8 Front Hubs that are a bolt on upgade for the MX5 Miata. While these are not our typical billet enduro stlye of enduro hubs, we have been racing with these on our shop cars in GLTC for the past ~5 years and they continue to take a beating! We have not found a single aftermarket hub that will even last a single weekend, sometimes even a single session.

Optional for Spec MX-5 Mazda part number F189-33-04X and a direct swap over from the MX5 part number NE51-33-04X
RX8 vs MX5 front hub upgrade TLDR: the RX8 front hub has bigger ball bearings and a better flange design for a higher load rating.
Here are the facts
While both bearings have similar external dimensions so that they can be interchangeable between the MX-5 and the RX-8 uprights. In addition to sharing a similar 140mm diameter hub flange that is 10mm thick, Internally is where the significant changes are.
RX-8 vs MX-5 front hub design improvements:
This is where the details matter!
