As I understand it:
The coil-over-shock double-wishbone suspension is nice because:
Pros:
*The wheels increase camber as the spring is compressed, allowing better tire contact patches while turning
*The rate of camber increase is theoretically manageable and can be tailored for every car
Cons:
Complex design
Expensive to design and build
MacPhearson Strut:
Pros:
Simple design
In a straight line, the contact patches are better
Cons:
Adjustable spring coilovers can become undone due to the twisting at the bottom of the strut.
Doesn't compensate for turning as well as the double-wishbones do.
Torsion bars are weird, and I dunno about them. My brother's 944 S2 has them, but I've never really looked at them myself
