Why dual coilovers per corner?
(OP)
The older jaguars and the ferrari testarossa have at each rear corner have two shock and springs, one coil over shock and spring fore and aft of the drive axle. The only explaination I have been given is for the jaguar with the suspension and shocks mounted to a subframe that was very compliantly mounted to the body. Where they were placed one fore and one aft for even load distribution so the compliant bushes between the subframe and main frame compressed evenly. I do not know if this is the full story however and I have heard no explaination for the ferrari. Any insight?

Sometimes this setup is seen with a trailing arm attached to the "I" arm.

The American method- to get good handling from any suspension just keep winding the spring rates up until the wheels stop moving in undesirable ways.

Witness our Monster Trucks, with four or more shocks per corner, to suspend a body and chassis that has to weigh less than the tires.
I.e., it's a fashion thing.

The main advantage re compact dimensions was to allow a lower boot floor over the suspension sub frame so that the boot had enough depth with a low body line.
I guess it allowed for a good all round compromise of good ride, good handling, low profile styling and good boot room.
Also an extra pair of shockers should give better damping.
