I wouldn't quite say that about a Ram clutch. I'm on my fourth Ram clutch & I do love them too death. I've currently got a Ram clutch designed to hold 500-550hp. It has some chatter(kevlar puck disk). If I'm coordinated, my footwork with the gas & clutch are well sync'd; it doesn't chatter. If I'm not in sync with my left foot & gas pedal... I sometimes have mild chatter. If I'm really bad and or in a tight turn while backing up situation; it can be quite horrible.
