Even those upper control arms could be lengthened to give you, essentially, a four link suspension.

I think the longer leaf will make it easier to distribute the spring loads onto the unibody chassis. Without a "real" frame, it would be hard to build a mount that could handle the torque of a quarter eliptic spring.

I guess it would depend on the frame structure and how it is integrated into the unibody. The Austin Healey Sprite/MG Midget used a quarter elliptic rear suspension albeit with much lower HP than you are using.

Somebody on metalmeet posted a pic of the sprite style mounts. It is a lot simpler than I thought it would have been.
