It really comes down to what kind of use you see for your car. D2 Coilovers are marked "racing only" at D2's own website. I am planning a mainly racing setup so I am getting these. Those who have them say they are not the thing if you want a comfortable ride.
Shoxshop also has a ST/Koni set that is supposed to be good stuff. (and possibly better for road use)
Just my $.02
