Bilstein PSS :: 99-05

Mazda has trusted Bilstein for its factory "sport" package shocks on the Miata for more than a decade so go with Bilstein coilovers for quality that will last as long as your Miata does. We sold TEIN here once...and nearly every set came back under warranty...but these Bilsteins work year after year after year. To insure maximum performance, these systems utilize Bilstein's superior monotube gas shocks (rather than 1980s technology twin tubes like much of the competition including TEIN coilovers). Large mono-tubes mean the largest available piston diameter for greater sensitivity and precise control. Patented digressive piston head design and deflective valving instantly reacts to changing road conditions. The monotube design also dissipates heat more effectively than a twin tube shock for cooler, more efficient operation and longer life. Lighter weight reduces wear and tear on suspension components. The Bilstein PSS Suspension provides the ultimate in STREET performance tuning. PROGRESSIVE rate 242-282 springs provide a ride as comfortable as the factory sports package but with far less squat and dive and much more precise control. Patented digressive valving keeps the wheels on the pavement and maximizes grip over a much wider range of surface conditions for confidence and control. Brian's Application Notes: Bilstein intends this kit as the ultimate street setup and should not be confused with the PSS9. The PSS9 is their dual purpose setup for the guy looking for something competent on street and track and it gives up some ride comfort in exchange for linear rate 343 lb springs and even more agressive adjustable damping. The picture shows the PSS9 with helper spring, the PSS uses longer 242-282 rate springs and does not need a helper spring.
