All MCS damper kits are built to order so expect an estimated 2-4 week build time after you order. If you chose to order online, you will be billed immediately. If you would like to call in the order (we prefer that) we process a deposit for the shocks up front, with the rest billed when they are complete.
Introduction
Vorshlag Motorsports is an authorized Motion Control Suspension dealer. The MCS RR3 external triple adjustable damper is the Motorsports solution for top level Time Trial competitors, Club Racers, and Autocrossers - even Pro road race teams. This damper set features a full 18 clicks Rebound control, 10 clicks of low speed Compression control, and 18 clicks of high speed Compression control - over a wide range and valved unique to each vehicle model's specific requirements.
Dampers are more than just a number of adjustments and click count though – the shape of the resulting curves is specifically engineered to give your car the most grip through the range of surface conditions and dynamic inputs your vehicle experiences in a competition environment.
High Speed Compression damping (above left) is easily manipulated on the 3W damper. With 18 clicks of adjustment, the user can control high speed shaft movements (4 inches of velocity and beyond) to make better use of their mechanical contact patch, resulting in faster lap times. Low Speed Compression damping (above right) has 10 clicks of adjustment, allowing the user can easily manipulate the pitch and roll of the vehicle in low speed shaft movements (0-4 inches in velocity). With 18 clicks of rebound adjustment (above middle), the user can easily introduce more spring control or change the balance of the car.
With the Schrader valves fitted on the ends of the RR2 or RR3 reservoirs, the ability to increase or decrease the nitrogen pressure in your damper is another adjustment. This allows the user to increase or decrease the overall support to the vehicle. Reservoir pressure can be adjusted between 100 – 275 PSI to help support the platform in fast cornering that generates large loads or to allow more weight transfer to generate more traction in low grip scenarios.
All the MCS dampers are built in the USA. They are fully rebuildable, serviceable and can be custom valved and upgraded any time here in the USA.

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 MCS damper kits. You can easily adjust camber track side with Vorshlag camber 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 spring perches. Ordering this option includes the associated Vorshlag upper spring perches made to work with these plates, springs and MCS struts.
SPRING RATES : While MCS provides you with the dampers only, Vorshlag offers the unique option for racers to pick their own front and rear spring rates at a reduced cost. These options will include new Hyperco or Eibach springs from our recommended packages. The spring options listed include our GT package for daily driven cars, the GTS package for street cars that are also used in autocross and/or track events and the GTR package for race cars that predominantly see track use. Coilover versions add helper springs and dual spring adapters to the rear spring package. If you would like to order custom rates not listed here, please give us a call. This can be arranged for typically no extra cost.

Rear Shock Location: For the E9x M3 and 1M you have a few options for rear shock mounts. First option is a divorced spring that puts the spring in the stock location with a dedicated ride height adjuster and Powerflex shock mount that allows the rebound knob to be accessed in the trunk. The Coilover option moves the spring to the shock body and includes an upper clevis mount that can accept spring forces. The rebound adjuster is located in the wheelwell. We can also supply the kit with no rear spring hardware and a pin style upper shaft so you can configure it as you like.
