Button, as per my explanation the 5L does not need an 'anti sway bar'/'anti roll bar'. These [IMHO] nasty devices add to single wheel stiffness and maintain stiffness with both wheels in phase. This is the opposite of what is required, for ride one wants compliant single wheel responses but then find a way of adding roll stiffness without increasing single wheel stiffness.
The links in the 5L are arranged so that in roll they start to 'fight' or 'lock up' thus increasing roll stiffness with the rate of roll stiffness increase controlled by the rubber bushes - this is done without stiffening the small displacements of single wheel inputs. So this gives good ride over road irregularities BUT with significant anti-roll from the geometry of the links.
Look at the work done by various car manufacturers now (BMW Mercedes etc) to reduce the stiffness of anti-roll bars and build in anti-roll with rebound spring control to improve ride.
Good to hear from you Bill - Regards Peter.
