Product Description

The Bilstein 48-121262 B16 PSS9 is a complete front and rear coilover suspension kit engineered for the 2004-2013 Mazda 3, 2005-2012 Ford Focus Mk2, 2004-2011 Volvo S40, 2005-2011 Volvo V50, and 2008-2013 Volvo C30 - all FWD applications. The PSS9 system replaces the factory suspension with height-adjustable, damping-adjustable monotube coilovers that bring genuine motorsport-grade tunability to the street or track. With 9 stages of manual damping adjustment dialing in both compression and rebound simultaneously, drivers can configure the ride from a compliant daily setup to a firm, performance-focused track setting - all with a simple twist of the adjuster knob.

Each unit is built around Bilstein's proven monotube gas pressure technology, tuned specifically to the weight distribution and suspension geometry of each supported platform. The threaded body design delivers a precise 30-50 mm lowering range with a 20 mm adjustment window per axle, while the aluminum spring seats and Triple-C-Technology® coating ensure corrosion resistance and long-term durability. Developed and proven at the Nurburgring, this kit is a direct-fit, bolt-on upgrade - though professional installation and a four-wheel alignment are strongly recommended after fitting.
