Since i don't race a lot, if i can get 75 to 100 runs out of this setup, i will be somewhat OK with running the needle bearings and washer combo.
And, if that doesn’t quite work out as planned....... you can always back it down a touch. Not everyone is experiencing the same short life span you seem to be getting out of them........so at least some of the issue seems to be combo related.
