well are you plan on tracking your car like on a race track or autox or just drags? I think for drags it won't make much of a difference long it as damper adjustment.
If you plan on tracking you car a lot, i would go with blesteins or a konic shock and spring combo.
I have d2's on my c32 and i'm pretty happy with them. I go canyon carving but i dont drag or track the car. I'm pretty happy with there performance, all the understeer is gone. They actually oversteer slightly at the limit which i like.
here's my review on my d2's

Also on a side note...all d2's, ksports and apexi's are made by apexi in taiwan. Differences is the spring rates. D2's have softer spring rates and the ksports are stiff. I would opt for thd d2's for a daily driver.
