The only reason mine was so cheap is becasue my rep and i are on good terms...and in a why it was a "gift" i got them for there cost (just above there cost) and in returen when i am on the track i support bilstein with some decals. kinda like a sponsor ship but not really. they don;t give me money for my car or anyhting like that. The kit they used is a custom PSS9 type kit. they are the similar in spring rate to the H&R's., As for details im not too sure....i just got them and am slowy going over the specs so i can remember.
Right now for street use im running on Eibachs and Sachs struts.
As for mas production or getting them for others...i will have to ask my rep...this was kinda a one time thing..but hey they may do it if they think theres a demand.
