Comp pack (ZCP) suspension is completely different to the optional EDC suspension. The damper "sport" mode of the ZCP EDC function is variable compared to the fixed setting of the "sport" mode of the optional non-ZCP EDC. Springs and EDC control unit is also different. Also, it is important to note that M3 springs vary even amongst the same model i.e. the springs of an M3 Coupe might be different to that of another M3 coupe, this is due to the varying weight of the cars due to different options fitted.
