Im no advocate of D2 suspension, however i wouldnt say the company lacks R&D because the front dampener has a stiffer spring rate than the rear. I can name many companies that design coilover for front wheel drive cars with similar setups. (Buddyclub, Cusco, Tein, HKS) Anyway through my experience of driving my mates car with a very similar setup, i found reducing the dampening on the rear helped in preventing oversteer. The front dampening was pretty much on full stiffness.
