Not to bring this rather unpleasant thread back from the dead, but there is a ITA CRX "With SCCA log book" for sale in the classifieds section.

It is advertised as having "10 pounds liberated from the flywheel" and a "modified throttle body".

Uhuh. Whatever. Make your own judgement, but if you're dumb enough to have a lightened flywheel, I guess you're dumb enough to advertise it as a selling feature!!!

Oh well.
