First question, you mean "screetch" instead of "scratch" don't you? Like "chirping" the tires?
And second, did either of you "grind" or "resurface" the flywheel prior to installation?
I know Fidanza says it doenst have to be ground, but some clutch manufacturers (most anyway) REQUIRE that ANY flywheel be resurfaced prior to installation, even new flywheels. Just curious if that was done, as I would imagine it would've helped cut down the break-in time from 6k miles considerably IMHO
