Hmmmm interesting. They are quite similar. My D2's have been sitting at my feet for the past 2 months lmao (mmm the coils are so theraputic for my toes). They'll go in soon, and I can't wait. I got mine on special for $1300. 36 way damper adjustability, camber plates, ride height...they are stiff however as mine are track rated. I believe Steve's are as well. You have to have kidneys of steel to have them, and I have to say I'm used to my other car in that regard so they are no problems for me.
