Perhaps of some interest (or not) I saw a 1970s race car at the weekend with inboard rear suspension consisting of Hydrolastic suspension units, probably off an Austin 1800 from the look of them, it was called an MG liquid suspension system but from what I could see they were standard hydrolastic units but instead of being hydraulicly (sp?) connected they were independent with a simple schrader valve on each rear unit so you could alter the hydraulic pressure and therefore the spring rate. I'll see if I can find a photo.

Found it! Here it is:

Very interesting! and would certainly help from a packaging perspective. However, don't they still need damping? Then where do you put the long dampers?
