Build A Faster Car - helping drivers engineer

I was looking into kit cars when I found this on one design:
http://www.daxcars.co.uk/anti-roll-suspension-01.htm

Move over unequal length double-wishbone- this new design seems like the holy grail of street car suspension design, except perhaps for packaging concerns from the extra linkage. Geometry and roll-center wise, this seems vastly superior to anything out there for a street car.

Advantages:
- No undesired camber change during body roll, bump, or droop(!!!)
- Maintains low unsprung weight of traditional double wishbone
- Very high roll center possible (not quite sure how this is modeled just yet)
