WestcoaST: I'm not sure what the real cause was. But I running it with the grease slinging out of it for months prob was not good.
I also know that wheel hop at the track is not resolved by 1 rrm on street tires.
I'm not bad at it for failing, although It didn't hurt my account right at X-mas. But, I played, it went faster than my goal, and then I paid.
