The Sachs has also gotten a reputation for susceptability to
clutch chatter (oft mentioned in the list archives), a condition which I
have never heard of with a LuK. To be honest I have my doubts as to
whether this reputation is deserved, as it's my suspicion that in most
if not virtually all cases the real culprits were worn motor mounts, an
uneven flywheel surface, or other external factors

I had a sachs kits in more than one vans with the Canadian disc and after
the first time the disc got hot from riding the hell out of it stuck in
traffic or the like it chattered.The cure was to replace the disc only
worked like a charm very time
Sachs now uses a mexican disc and has no such chatter problem
I sell lots of the sachs kits with no complants
