[s-cars] sicness continues

[Kirby Smith]

I recently had the same clutch setup installed, the disk part as
somewhat of a surprise as my speculative choice would have been metallic
pucks but with springs.  I can concur that this disk will not slip, at
least without exceptional effort, and even then all one gets is a few
chatters before locking.  The plus side is of course being able to
launch the car and not having the clutch slipping all the way to redline
in first, as my OEM clutch did.  However, there are a few negatives. 

a) Without any clutch slip, the drivetrain gets jerked and the CM joints
get pounded unless rpms are closely matched
b) Without any clutch slip, during shifting torque transients will be
put into the tires that may cause loss of traction in snow
c) Without any clutch slip, refined acceleration levels are difficult
because the action of rpm matching simultaneous with power matching is
very difficult, at least for me.  Fortunately, my wife hasn't been in
the car since the change.  :)
