What happens when you use a Boge/Monroe Sens-a-Trac on a lowered car is
you get a really weird force/velocity curve. The B/MST dampers have a
fairly stiff extreme travel and a "Comfort Zone" at stock ride height.
This "Comfort Zone" is created by machining Bypass relief's into the
damper tubes to allow a little more fluid to flow AROUND the valve stack
rather than through it. When you lower a car and install these dampers
on it you are working BELOW the relief's in the "Aggressive" zone, when
the strut extends (Rebounds) it can get into this "Comfort zone" and
reduce the damping allowing the tire to "patter" over washboard surfaces
doing really weird and horrible things....
This is one of the reason's that I suggest to people that they Purchase
an engineered Kit and not go with a collection of parts picked out of a
catalog because "I hear great things about this or that"
Hope that helps out.
