Wheel bearings and Hubs

[rx7chris]

What about the MKIV stuff? Something I should be concerned about?

The Mk1 hubs are very fragile and should be replaced at the end of every season. I have had two Mk1 hubs fail in nine years of racing and luckily both failures occurred in parts of Summit Point where I was able to coast the car to a halt with without hitting anything.
MkII hubs are less fragile but will fail eventually (and just as spectacularly as the Mk1 hubs).
MkIII hubs are very stout. But like any racecar part they should be replaced regularly.

I have no experience with the MkIV cars in racing trim. But I have taken apart the wifes street MkIV and the design seems to be better than the MkIII.

I replace my hubs EVERY year.
Not to say they wont last longer,
but when you break a hub at the track....ummm yeah you're done

then you're kicking yourself for not replacing them...
I like to call it..."cheap insurance"

Same here....mk2 and I replace my hubs ever off season along with Bearings.

I probably go 1.5 - 2 seasons, but of course that depends on how many races comprise a season. I also bring a set of front hub/bearing carriers loaded with fresh parts to every event, so that IF something does go bad, it is easy to swap in the assembly at the track.

very good idea

Greg, I bring a spare set of hubs, 1/2 shafts with CV's, calipers, rotors, lower control arms, shocks, struts, tranny, and brake pads to the track. I can replace almost an entire front corner (don't carry springs or camber plates) at the track.

I re-use my hubs, but have them magna fluxed to check for cracks, and have new bearings installed every year. All of the spares go on the car over the winter, and the old hubs/bearings and 1/2 shafts get replaced / rebuilt every winter.
