Clutch Doctor is where we went.
! Extremely impressed with the design, construction, features, and performance
of the Clutch Doctor clutch.
Price is right as well.
Thanks to John and Russ.......
I didn't realize what an expert John Hagen is on clutches. I guess that would
be a further endorsement.
I think there is a picture of the unit is around somewhere....perhaps Sean has
it.

can build most anything. We us a"One Piece" disc--no rivets-no 'Marcel" with

street. Ceramic buttons run cooler and can take more oil. Must use steel
insert if using aluminum flywheel. Sprung center section is advised for road
racing--ie not solid disc.

We built 100M units per year. I used to give clinics on clutches---sooo
