The Bilstein B14 (PSS) suspension kits feature ride height adjustability in an OE quality, direct fit package. These kits offer monotube performance dampers with matched springs that are tuned for each specific application. The zinc coated and threaded body design will give you the flexibility to find the perfect ride height setting for your intended use while providing unsurpassed protection against the harshest road elements.
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 lowered heights 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.
The PSS kit is designed to be a "bolt on" modification using your OEM top mounts. We suggest adding Vorshlag camber plates for any track use, which gives more front alignment adjustment and saves tire wear on track.

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.
SPRING PACKAGE: The "tapered" springs that come with the Bilstein PSS kit are a great starting point, and are made to lower the car and work with the OEM upper spring perches and top mounts They are soft and very comfortable on the street and work well if you occasionally track your BMW, but you have exactly one choice of springs that will fit this setup - what is included in the PSS kit.
But... if you plan on using your car more for competition (autocross or road course) use, then we can set you up with linear style 60mm coilover coilover spring package that have a stiffer spring rate, are lighter, and offer more inboard wheel & tire clearance. Once you convert these PSS dampers to use 60mm springs there is a wider range of spring lengths and rates to choose from, for further tuning. When switching to a linear style coilover spring it is HIGHLY RECOMMENDED TO USE VORSHLAG CAMBER PLATES as they will be configured with the correct spring perch. You will not be able to use your OEM top mounts with the GT Package spring option.
