I have broken a stock piece ice racing 5 years ago, and an ACR piece roadracing- big springs and Konis and poly bushings and one curb exiting a chicane on my home track that is probably pretty hard on things. There are two Napa parts listed, one Chinese, one SKF. The Chinese one I would not even put in a street car. I got an SKF kit, so we'll see how it performs this weekend.

Thanks for the hub number- the only listing I had seen was the upgrade kit from MP. It never occurred to me to look for the hub only. Thanks.
