Bryan;
Most clutch manufacturers warn about increased driveline shock loading when
you go to a solid hub clutch disk. Non- racing clutch disks have springs in
the hub that cushion the engagement shock. Ditto for a clutch disk with no
"marcel"; that's the wavy flat spring that allows the clutch friction faces
to engage progressively. Most racing clutch disks don't have any marcel so
their engagement is sudden and brutal. "You pays yer money and you takes yer
choice."

Subject: Some drive line thoughts for Mr. Truk
Kieth, do you remember some years ago when the Winston Cup cars were using
new multi-plate clutches?
As I recall, they were having problems breaking drive line parts leaving the
pits. I think most of these problems were occurring at the super speedways.
Could a very, very positive clutch create unacceptable shock loads due to
the high inertial loads imposed when trying to spin tires/wheels with
a 200+ MPH gear in the rear axle?
Just a crazy thought..??
