Have purchased ceramic bearings for front wheels. No way to compare since no runs on old bearings. I have been told by cpl they are worth .02 in ABA test. Would like rear end ceramics also,not happening anytime soon.I thnk cost around 1500 for all. Wondering if anyone has tested difference or knows how much et they are worth.
Watching video of rear spinning free.I can believe its worth 3 or 4 times what front ones are.
