myself I am not really into ceramic bearings.... IMO they typically fail sooner then steel and offer absolutely zero performance benefits....it kills me to see people saying ceramics help performance as they do absolutely nothing measurable or noticeable...IMO a whole bunch of hoopla over nothing tangible ! I have dyno and track tested ceramics many times over and my results were nothing noticeable...dyno didn't show any gains, and neither did any back to back track testing........that is my story and I am sticking to it,..bur hey, what do I know about engine performance !
