The goal is to use them in the rear to replace a unit that has not proven itself to be reliable under the extreme conditions of autocrossing and road racing.
The A.C.Delco unit looks to be the one to get.
Availability is a plus as not too many OEM bearings are available.
I just experienced a total failure of a bearing at Thompson Speedway road course a month ago.
It ultimately took out the transmission and caliper.
Not a fun time at the end of their long main strait at turn entry.
The front bearing issue is still to be solved.
The FIero rear hubs should be very reliable if you are using quality Timken, Bauer, or SKF made bearings tightened with the axle nut to 200 ft lbs. AC Delco is usually a quality brand but who knows who makes them today? AC Delco is now mostly made in Communist China. We've seen 3800SC's give 12, 11 and 10 second quarter mile runs with high quality hubs without a problem. Drag racing would also appear to be extreme duty use. What is a problem are the cheap low quality Chinese made hubs. I've seen those hubs on other peoples cars fail in under a year of normal driving. They are made from high impurity recycled inferior scrap steel, and IMO complete garbage. Quality bearings are forged from pure iron ore, not recycled scrap steel.
