Stephen is on the mark again. The Tiger's front sway bar is really
binding. To check it out, take it off and go over something like the
small curb in your driveway. You will really notice the difference. I
make my own design that use poly bushing and spiracle ends, but am
looking at a Mark 2 design as well.
Now Stephen's rear suspension is really nice, and maybe one day.
Stephen, since Griggs made your suspension for you and you are a former
customer, could you ask them if two way adjustable shocks would work to
control the dive. As you know shocks like Koni's adjustable shocks only
control the rebound, not the compression.
Suspension theory several years ago was going towards lighter springs,
and heavier shocks and sway bars.
Griggs is a specialist and should be able to answer this question with
some authority.
