- The suspension has been lowered by 10mm. The spring rates are the same, but the springs themselves are shorter, to compensate for the shorter stance. The suspensionís shock damping was also adjusted by the M division. This was in order to compensate for the lower ride height, primarily for rebounding damping rates as opposed to actual compression.
You need both the ZCP suspension and the ZCP coding done for the whole system to work properly.
