Product Description

The Bilstein 49-115604 is a B16 DampTronic complete front and rear coilover kit for the 2005-2012 Porsche 911 997 generation. DampTronic is Bilstein's PASM-compatible coilover platform -- the dampers integrate directly with the factory PASM electronic suspension control system, retaining all active damping modes and factory controls without modification or recalibration. This is the key distinction from standard coilover kits: the driver retains full use of the factory comfort, sport, and sport-plus damping settings while gaining the ride height and spring rate benefits of the coilover system.

The threaded body allows 15-35mm of ride height adjustment across a 20mm range at both axles, with 10-stage manual compression and rebound adjustment for fine-tuning beyond what the factory PASM modes provide. Progressive-rate blue sport springs are application-specific to the 997 platform. Triple-C-Technology zinc coating on all body components provides long-term corrosion resistance. Includes spanner wrench for height adjustment. Requires PASM option I475 -- does not fit 997 models without factory PASM. Road and motorsport tested at the Nurburgring. Made in Germany. Backed by Bilstein's limited lifetime warranty.
