I was at Summit Point yesterday for FATT. During my 2nd heat I had my left front hub fail. It let loose in turn 5-6 or so, and if you know Summit, that's about the slowest part of the track. Which is right after the part of the track with the highest pucker factor IMO (downhill at 80-100 depending, about a 30 degree turn a little off camber and max braking soon as you're through it). So I am OK and there is no body damage.
The hub flange sheared right off, and the wheel getting pushed back it must have bent up either the brake caliper or the slide pins, the caliper doesn't float any more. A guy with a TA next to me thankfully had a spare hub, so I got that on and drove carefully home. This was a Mike Minear hub so I'm contacting him to see if he wants to inspect it. I'll probably get a new one from him over the winter.
I'm thankful that was all relatively low drama. If that happened almost anywhere else on track, well all the other places are pretty high speed, and it would've been a real wreck, literally.

I have not heard from Mike yet. But, at the autocross last week, the other side broke off in exactly the same fashion.

I am Doug's friend and it was my 92 Vette that had the hub failure at Mosport (there is never a good spot to have a hub failure there).

I will expose my stupidity here in the hope someone else doesnt make the same mistake. I bought a "cheap" hub off the net from an American company which stated the hub met OE specs. I thought, "well it will vibrate or give me some sign of failure, so why not try it? This turned out to be a bad move. It lasted 10 laps and one corner. And just like in the earlier post I also had a low brake pedal, but didn't think much of it. In retrospect, the bearing in the hub was heating up and transfering the heat to the caliper and boiling the fluid, and or flexing the hub causing brake piston pushback. Eventually, well rather soon, the bearing froze and the intertia from the wheel/rotor snapped the stem of the hub like it was wood causing the wheel/rotor/brake line to leave the car at 90 mph. Thankfully I didn't hit the wall.

If anyone would like to see pics of the failed part, email me at chris dot lawson at haltonpolice dot ca I will send them asap

I contacted SKF as they make hi perf hubs for C5 and C6 Vettes. Unfortunately not for C4's/Camaros. The best I can find right now are Timken. Any suggestions? F body and C4 hubs are essentially the same.

The moral of the story, which I should have been smart enought to know, is buy top quality items for parts that matter!
