First post in this thread lists the stock spring rates. The assumption here is that the stock rates are the same for all configurations (DCT/Manual, Sunroof/Slicktop, Sedan/Coupe) The reason I bring this up is the ZCP spring rates seem to be per configuration and unknown.

My question is (and I have spent hours looking for this information) what are the spring rates for the ZCP springs? I am actually really surprised no one has listed this to date (unless it was my lack of searching skills). We know there are springs listed X6 and X5..so can we work to fill out the ZCP spring rates as a baseline for anyone looking to go with non-oem vendors both in coilovers and spring sets? Does anyone have this information.

ZCP:
Front Spring Rate: (Labeled M3/X6)
Rear Spring Rate: (Labeled M3/X5)
