Bilstein PSS9 B16 Adjustable Coilover Kit – Porsche 987 Boxster & Cayman (2005–2012)

Description

The Bilstein B16 PSS9 Coilover System is a premium, height- and damping-adjustable suspension upgrade engineered specifically for mid-engine Porsche 987 Cayman and Boxster models. This fully adjustable coilover kit replaces the factory dampers and springs with German-engineered monotube gas shock absorbers and progressive sport springs to deliver sharper handling, improved cornering stability, and customizable ride quality from daily driving to aggressive track use. With nine manually adjustable damping settings, drivers can fine-tune compression and rebound to match their driving style and road conditions. The threaded body ride height adjustment allows approximately 30–50 mm of lowering for an optimized stance and lower center of gravity without sacrificing comfort. Built with corrosion-resistant coatings and motorsports-tested components, the B16 PSS9 system offers durability and performance where it matters most.
