Bilstein PSS10 Coilover System with PASM Porsche 997 C4S & TT 05+

Utilizing Bilstein's monotube shock absorber design for heat dissipation and ride control, the PSS10 Coil-Over System, evolved from the PSS9 system, adds a matched performance spring and threaded ride height adjuster to provide a complete suspension system for your vehicle.

The Bilstein PSS10 Coil-Over System offers ten vehicle adjustment settings and includes numbered adjusters at the base of the shock body so you know exactly what setting you are on without counting clicks. Set your vehicle low and tight for optimized performance or revert to a more stock-like ride height and handling characteristics.

This system features both coil-over and standard monotube gas pressure shocks with performance level valving along with application specific, progressive rate coil springs. Ride height adjustments can be made on the vehicle without removing the suspension. The solid aluminum spring seat and lock nut allow a selective adjustment of the vehicle's ride height. Spring travel and vehicle body height change, but the spring seat remains pre-loaded throughout the allowable range of adjustment.

Additional Features:
-Ride height adjustable
-Wrenches to adjust front and rear ride height included!
-Lighter weight reduces wear and tear on suspension components

Fits: Porsche 997 C4S 05+ and 997 TT 07-08
