Porsche Dynamic Chassis Control changes the suspension equation on the 991. That means the springs underneath need to be engineered for it specifically, not just borrowed from a standard kit.

This KW H.A.S. kit is purpose-built for 991s equipped with PDCC. The adjustable spring perch lets you set your exact ride height after installation while your factory PDCC-equipped dampers stay in place. If your 991 does not have PDCC, see the non-PDCC H.A.S. listing.
