[convincor]

See post #2 of this thread.
I'm using one, as well as a couple others I know. One of which does a lot of drag racing.
I havn't driven it that much yet, but no problems so far.
Had my machine shop check and match the balance to my old flywheel which was "0" balanced and it was perfect.
Once mounted I checked run-out and that was .006" total. Max allowable by the books is .017"
