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.

Carburizing is an interesting idea, but I don't know if the blanks can be obtained in 8620 or not. It's my understanding that 4340 is not particularly well suited to carburizing. Yes, no?

Yes, my understanding is that 4340 already has too much carbon for carburizing since carburizing adds carbon to the surfaces. It might be good for induction?

I really appreciate all the help and knowlege I'm getting from all of you.

It is a noble cause so I’m glad to help.


Question on a different subject, what happened to the ‘Hardbar’ or whatever hubs that were made for the corvettes and why wouldn’t the C4 version work on the 4th Gen?
