All good points. The SD1 suspension isn't a true
torque tube setup anyway. A Panhard rod would do in
place of the Watts links.
What really concerns me is the business about the
spring and shock mount posistions.

The spring mounts for the P6 are in the same relative
position as on the TR7/8. I admit that I've never
designed a rear suspension, so if you have the time,
tell me something about the issues related to shock
location. It may all come down to a definition of
"adequate controll." Certainly the P6 rear suspension
is much better at controlling road wheel movement than
any straight axle setup could possibly be.
Also, using the leading links would mean

Again, we're not re-inventing the wheel, just
transplanting SD1 pieces.

Now THIS is an issue. Although I prefer the Watts
links, a Panhard rod might be easier to fit but you
still have the problem of where to locate the rod end
mount at the body end.

Residual pressure and front/rear proportioning do need
to be considered, but the M/C should do quite well. An
adjustable proportioning valve is an easy fix for the
Keep talking, Vern. By the way, I have your heated
rear screen out if we can figure a way to ship it.
