Upgrade your Z4's appearance and handling with this Dual-adjustable coilover system from Bilstein. Bilstein's PSS10 system is the latest addition to their suspension lineup, replacing the legendary PSS9 System. Evolving from a history of worldwide racing dominance, Bilstein created the ultimate automotive performance suspension system for the 1999 to 2005 E46 3 series; the PSS9 adjustable coil-over system. After the rave reviews and feedback of thousands of PSS9-equipped BMW owners, Bilstein has raised the bar once again and evolved the iconic PSS9 suspension system to the PSS10 Coil-over Kit. It encompasses everything that the PSS9 offered, with several advancements and user enhancements. For one, the dampers are now EVEN EASIER to adjust, and include numbered adjusters to the base of the shock body. The PSS10 shocks now offer TEN adjustment settings (up from the 9 offered on the PSS9). To insure maximum performance, these systems utilize Bilstein's superior monotube gas shocks, featuring:
* Largest available piston diameter for greater sensitivity and precise control. * Patented digressive piston head design and deflective valving instantly reacts to changing road conditions. * 10-way adjustable dampening knobs that "click" from soft to hard with no tools or jacking required. * Monotube design dissipates heat more effectively than a twin tube shock for cooler, more efficient operation and longer life. * Weather resistant coating to resist oxidization, and ensure long life. * Lighter weight reduces wear and tear on suspension components. * Ride height is adjustable from -1.0" to -1.75" front & -1.0" to -1.75" rear (minimum 1" lowering) * Wrenches to adjust front and rear ride height included!
