Introduction
The Bilstein B16 PSS10 (and PSS9) kit is a race inspired system, providing the ultimate in high performance tuning. The manually adjustable monotube gas shock absorbers feature 10-stage precise compressing and rebound settings, from comfort to competition. The threaded body allows accurate adjustability of the front and rear progressive springs to achieve the vehicle ride height (30mm to 50mm), center of gravity and level of performance handling desired. Bilstein's patented Triple-C-Technology coating ensures long-lasting resistance to corrosion.
The ride quality is without compromise and belongs on both daily driven and entry level HPDE track cars alike, with the included Bilstein springs. The ride height adjustment range is large and it is capable of the lowered height shown above as well as taller ride heights for those that need to drive in snow or on gravel roads. The beefy inverted Bilstein struts are VERY STRONG and can work for many forms of motorsport as well on a variety of road types, and with the twist of the adjuster knob can help you dial in your preferred ride and handling.
We suggest adding Vorshlag camber plates for any track use, which gives more front alignment adjustment and saves tire wear on track. Many of the various options avilable with the basic PSS9 kit are shown in the pictures and drop-downs below.

Choose the appropriate options and model alterations from the drop down menus below. These options will affect the final price as shown for each option. All optional packages and parts include significant discounts when purchased with shocks rather than buying the parts separately.
CAMBER PLATES : We highly recommend Vorshlag camber plates be used with Bilstein strut kits, but the shocks can be used with the OEM upper strut mount for racers on an extreme budget and/or where class rules do not allow an upper camber plate (such as SCCA Stock Class). Easily adjust camber track side with Vorshlag camber/caster plates. Over-sized spherical bearings are designed to withstand the rigors of street and track abuse. All components are plated for maximum corrosion resistance and long life. Please see the product entries on this website for more information about the Vorshlag camber plates and perches. Ordering this option includes the associated Vorshlag upper spring perches made to work with these plates.
REAR SHOCK MOUNTS : Vorshlag's new and improved Spherical Rear Shock Mounts (RSMs) for the BMW E30/36/46 are back! Optional Rear Shock Mounts include Vorshlag Spherical design or Heavy Duty rubber E46 M3 style. We recommend the spherical RSMs for most users that see any competition use, such as autocross or track events. If the car is a daily driven vehicle only and/or the user is worried about bad roads and any additional NVH transmitted through a rear spherical mount, then choose the HD rubber style instead. Our HD rubber RSMs will be machined (by Vorshlag) to fit the 12mm diameter upper pins on the MCS rear shocks at no additional charge (BMW mounts are made for a 10mm diameter upper pin). The advantage to spherical RSMs is their ability to transmit reactions to shock forces instantly and direct - something that shows up on a shock dyno plot. 
VORSHLAG RSM REINFORCEMENT KIT : Many BMW models are prone to cracks near the rear, upper shock mount bolt holes from both street/track use with higher cornering loads (and higher damper forces) as well as normal street use over extended time periods. Bolt these steel reinforcement plates on top of the rear shock tower sheet metal to strengthen this known weak area and prevent these cracks. Can be used with OEM style rubber RSMs or spherical RSMs. Can be bolted or welded in place. To install just place above the shock tower, underneath the RSM top nuts, as shown below - takes mere minutes to install and can be found HERE!
SIGNATURE DELIVERY : Orders over $2400 require signature delivery. Please plan on that when ordering.
