Thank you. You have rated this product.
The Bilstein PSS10 Coil-Over System offers ten vehicle adjustment settings and includes numbered adjusters at the BASE of the shock body so you know exactly what setting you are on without counting clicks. Set your MX5 Miata low and tight for optimized performance or revert to a more stock-like ride height and handling characteristics. This system features both coil-over and standard monotube gas pressure shocks with performance level valving along with application specific, progressive rate coil springs.
Ride height adjustments can be made on your Miata without removing the suspension. The solid aluminum spring seat and lock nut allow a selective adjustment of your Miata's ride height. Spring travel and Miata body height change, but the spring seat remains pre-loaded throughout the allowable range of adjustment. Spring rates are 330 front, 230 rear.
PICTURE DISCLAIMER NOTE: File photo used here...actual kit for NC uses high clearance design rear spring much like the stock style rear springs and the rear assembly re-uses the factory aluminum top mounts. Front assembly looks more like the picture here with front standard race spring and helper springs. Does NOT include any endlinks.
* Minimum ride lowering is one inch....and you can lower the car nearly three inches.
* Wrenches to adjust front and rear ride height included!
* Lighter weight reduces wear and tear on suspension components.
About the Bilstein Shocks Included in this System:
All Bilstein gas pressure struts/inserts and gas pressure shock absorbers operate on the same principle. They are manufactured with the rod pointing down into the strut tube, thereby utilizing the thicker, stouter body portion of the shock absorber to dissipate side loads. Consequently, due to the increased diameter and surface of the pressure tube, the Bilstein gas pressure strut/insert or shock is better suited to take increased side loads when compared with the conventional version. Additional advantages, based on development strongly influenced by the motorsport industry, include greater stability, better road handling, and accurate steering. And extremely high quality manufacturing and materials as well as a weather resistant coating to resist oxidation, mean Bilsteins will last approximately four times as long as Original Equipment.
Battling Heat Build Up:
Conventional shocks trap the heat within the shock body and prevent adequate dissipation, making them prone to heat build up, fade and eventual failure. Bilstein's patented design allows the excessive heat from the oil to transfer to the outer surface of the shock body and dissipate more efficiently. The dividing piston also permits the oil to expand as heat builds, preventing aeration (foaming) and viscosity loss. This allows the shock to maintain full damping characteristics as temperatures rise. The tube of a Bilstein gas pressure shock or strut is fabricated using a special extrusion method. This process achieves an extremely tight peak-to-valley tolerance and maintains consistent wall thickness. Bilstein's seamless monotube design provides superior tube strength while maximizing heat dissipation and shock life.
Ride Comfort and Performance Without Compromise: The piston head design allows independent tuning of the compression and rebound damping forces to provide optimum ride comfort and performance without compromise. It features fewer parts than most conventional designs. The product's simple, yet exceptionally functional digressive design contributes to the extreme durability and long life of Bilstein Shock Absorbers.
Better Built Bilstein's shock bodies are precision formed through a unique seamless extrusion process. This provides superior strength along with high finish tolerances. The shock body is then treated with a special paint finish durable enough to withstand grueling 240-hour salt spray tests. The finished body is mated with a solid, induction-hardened steel chrome plated and polished shaft, machined valving components and highest quality seals. Bilstein products are backed by an aftermarket lifetime warranty. Spring rates 330/230 f/r.
