The engineers at Bilstein have created the ultimate race-inspired suspension - the PSS9 / PSS10. This innovative suspension system delivers unsurpassed driving performance. The manually adjustable damping mono-tube gas shock absorbers feature 9 or 10-stage precise compression and rebound settings, from comfort to competition. The threaded body allows accurate adjustability of the front and rear progressive rate springs to achieve the vehicle ride height, center of gravity and level of performance handling desired. The Bilstein B16 system puts you in complete control, providing the kind of precise suspension tuning formerly available only on race cars. From a weekend of competition to daily driving, this system provides perfect handling performance for every situation.
