already did contact them, and i was tuning on a really HEAVILY built engine. so i don't think i'm still at the lower power output i was at. the ACT rep was puzzled and just suggested i do not use unsprung discs anymore.
there's no discoloration of the disc, the pads aren't worn so it didn't fail due to heat or slipping. the center was torn out. and the splines were almost gone.
anyways, just showing what happened when i thought i destroyed my transmission. instead i found this clutch this way.
