For the record, these are available here. Roller bearings, billet hubs, AUD1200/pr. Apparently used by some racers here, but I have no personal knowledge of them. These are cheaper here than the Miatahubs (low Aussie, freight, import/tax would push these above AUD2k probably), but the low Aussie might make the Bosnjak ones competitive going your way, or for buyers from third countries. A group buy might bring the price down too. Obviously, you would need to do your own due diligence, but I assume the vendor would be able to put anyone interested in touch with users. (For the record, I have no financial or other interest in this vendor)

Bosnjak billet NA/NB front hubs (two photos in middle row - sorry, couldn't get them to show here)

However, I imagine the BMW hubs would be the go, if/when they get proven, as far as cost-effectiveness goes at least. I hope.

 

Gents,

I replaced both front hubs with the Centric Premiums (as they are outta-the-box, no re-lube) after having a failure of a brand new ebay hub that had no name bearings but the metal inner seal. I had never seen one of those before, so I said WTF, let's give it a try. It lasted one track weekend. Unfortunately, I had one of the new premium Centrics fail in one track weekend as well. I bought it from Rock Auto. I'm going OEM.

 

You could also give these a try.

Pics of the Centric failure? Did the hub crack or bearing simply wear out?
Details of the car, tire size/model, pace compared to Spec Miata, curb hits?

 

The driver's side developed a little bit of play by the end of the event. About 500 miles total driving. Nothing dramatic. The nut torque checked good. I drove her home that way. I'm not a big curb user at VIR, but curbs I do use are on the opposite side. 225 NT-01s on 9" 6ULs. We were in the 2:18s managing temps by short-shifting.

 

Maybe a dud then. SCCA SM record is a mid 2:14, so with some power and NT-01, lateral G was likely not crazy, and then no curb abuse as well. Sounds unlucky.

 

Check to see if there was any grease in it to begin with. I repacked 2 new timken hubs and one of them was completely dry on the inside bearings.

 

PSA: Always pack new bearings on first installation unless permanently sealed type.

 

The Wilwood hubs have been posted here somewhere. Might as well link them here too. Thoughts?

Edit: Neg cat? I thought posting this in a SOTU thread should show all options available. That bad, eh?
