CERAMICS!!!!!
.................CERAMICS!!! I always thought ceramic was a waist of money.
Then, my bud said he had a gallon on a set, so I got me some! I got 4-5 races (that's practice, qualifying, & mains) out of one set. btw- when I did finally replace them (with ceramics) they had NO grit & no sighn of wear whatsoever, IN TRUGGY no less! The only reason I took them out is, I don't know the "limit" to them. I now have perfectly good practice bearings, or, engine break-in bearings.
