I have AMS motor mounts and an exedy twin and it also makes this noise. At first I thought it was a diff going bad but its not. Its normal

 

sounds like typical clutch chatter. When you upgrade clutches like this, alot of cars will have clutch chatter. Some do it, some dont. Can you make a video so we can hear it. Maybe we can help you better if we listen to it.

I just installed my quartermaster. This is my first twin disk and I understand some noise is normal and all by my engine/ trans shakes in 1st gear in low RPMs. Is that normal also? I haven't taking the car out for a drive and just tested it out on the jack stands so now load on the wheels. It also makes a clunking type noise. Any info would be great.

 

qm is a race clutch. Just like a tilton unsprung hubs equals nasty engagement. Unsprung equals worse dd and harder on drive train but capable of holding more horse. Sprung like an exedy twin which i have and need a rebuild its not noisey except now its breaking so it makes some noise when i dont have the clutch pressed in. But the dd on a exedy twin is great to me even in chicago 90 traffic sometimes haha
