Yeah, I'll second Jet on that. I bought a used QM with no instructions and I put one of the discs on backwards(their website directions are wrong), big mistake. Now it's rebuilt by PTT with their TOB and a 2G slave. Coming from a ACT 3100, this was a big improvement, but it does make some noise and drives like a typical non-sprung hub clutch. Engagement isn't bad and the pedal pressure is nothing, but you're always aware your driving a race clutch on the street. I'm definitely not looking back.
