[s-cars] short shaft

[Aaron Taylor]

Some rheomagnetic fluid ought to work nicely inside the coupling to make it
connect when needed...

Bill,

My vote would be some sort of a collar.  I think welding would alter
the spring rate of the bar too much.  If you can do a cold slice in
the middle, machine some splines in that would match a very stiff
collar, that shouldn't alter the spring rate too much.

or you could find some sort of electromagnetically
activated/deactivated spline, then you could do some active ride
control - leave it decoupled for staight line ride, and have it rigged
to couple upon a certain steering wheel angle / lateral accel / yaw
rate...  That would be fun..  But I digress..

Perhaps the cheapest solution is to find out from Hap if the new
HRSB's are HapperLonger....

Cheers,
Keith
