Mods, I don't see a track section so I figured this is better than any place.

This is a Mazda, so I wonder if it suffers from the same crappy front wheel bearings that my Miata does? The Miata won't last too long at the track with R-Comps and it's OEM bearings. Does the same apply for the FD3S? Are they rebuildable?

Thanks,

Adam

 

heres a link to the race car tech section

https://www.rx7club.com/race-car-tech-103/

and wheel bearing failure is not very common in FD's. its not that i know of anyway.

 

Wheel bearings can last if no dirt and/or water gets into them..that's why you keep the dust cap on.

That said both my fronts are solid, and original I assume. However both my rears are bad lol. Because they both have no dust covers on them lol.

I actually have a BRAND NEW timken front bearing with hub for sale if you're interested. I literally received it in the mail then found out my rears were bad not the front. Lol

 

^ Whether or not the dust caps are on has nothing to do with the question the OP has asked.


He is referencing the extremely high loads that wheel bearings will see when on track using very sticky tires. Those are two different scenarios. Aparantly when using R-comps on miatas the loads exceed the design limits of the OEM bearings. He is asking if that is also a common problem with tracked FD's. which to my knowledge is not as big of an issue with our cars.

 

Thanks for the link to the track section that I am too dumb to find and thanks for all the feedback guys. Glad to know Mazda put better parts on their real race cars.

 

You're not likely to see "failures", but I did notice much less brake pad knock-back with Fresh hubs/bearings, as you might expect.

 

Did you buy yours at your local dealer?
