I am on the same search!
I had the drivers side hub fail in the last race. It was a Honda OEM unit that I replace only 9 events before that. They were double weekends, so thats 18 races. I was hoping I could get a year out of them, but I guess not.
Replacing them every 5-6 races is a LOT of money. Wow. For me, that is every 3 weekends, and almost 4 times a year.
I would like to try a set of hardened ones and see if I can get a year out of them!
Anyone have any tolerance issues with hardened hubs? I have heard that it can be a problem!
