Contact us if you want us to help you complete your track coil overs!
With incredibly tight machining tolerances versus other mass production methods, these hand-crafted dampers are designed with only premium materials versus less durable and costly housings and internals. MCS pays close attention to even the smallest of details to provide repeatable results at all temperatures and shock settings. These ultra-premium dampers have a feel, ride quality, and grip capability that lesser dampers simply can't match - you absolutely get what you pay for.
Motion Control Suspension (MCS) has over 50 years of experience in the racing suspension industry and have created the newest, and one of the most advanced damper systems on the market today. The secret to MCS success is in the valving - co-developed with BimmerWorld for BMW E9X M3. The SA shocks have 18 clicks for rebound and each setting is distinctly different than the others. This does let you tune the damping control for a variety of situations and surfaces. A street setting has tremendous compliance even with stiff springs. And track settings have plenty of control. An MCS-unique blow-off valve is also part of the package. All MCS products are designed from a blank canvas, a foundation of winning damper products – the MCS damper is the absolute best product that can be produced.
Factory EDC: these coil over shocks replace the factory EDC shocks. However, the EDC system must either be disabled via programming (coding) or with a separate EDC-delete module.
Related Items:
Front Camber Plates. Ground Control or Vorshlag. These MCS dampers require a set of camber plates for the front mounting point. Camber plates must be sized correctly for the MCS strut pin and your spring size. If you want to re-use your existing camber plates the bearing spacer inside must match the MCS strut. Contact us with any need for the correct parts.
Rear Shock Mounts. For performance reasons the rear shock uses a 12mm shaft instead of the OEM 10mm shaft. New rear shock mounts are required and must have an ID of 12mm.
Rear Spring Perches. Choose from a fixed height-adjustable perch or an articulating / pivoting perch. This sits above or below the spring to provide rear ride height adjustments.
Rear spring note: in a divorced rear spring (not a coil over rear) the spring perch inside the rear control arm is slightly too large for a 2.25" spring. If we build a complete package for you we will supply 2.25" front springs and 2.5" rear springs. 60mm springs will also work in the rear. The Spring Diameter options above are for perches for the front springs.
Spring Thrust Bearings. These are discs that allow the spring to rotate with the steering angle and prevent binding. We have Torrington needle bearing sets or friction slide discs. These are optional but well worth the low cost. 2.25" springs only.
Sway Bar Links. Adjustable sway bar links are required for the front and recommended in the rear. Stock front links are too long so shorter and adjustable are required. Rear links are recommended to set clearances.
Sway Bar Bushings. Highly recommended in the front because the factory rubber bushings do not allow proper articulation when the E9X is lowered.
Springs. MCS are sized for either 2.25" (our preference) or 60mm ID springs. Spring rates and lengths are completely variable and are decided based on intended use, ride height, specific tracks, and other factors. You can buy springs a la carte or contact us for a bespoke spring package. We prefer to use a helper spring in addition to the main spring in our kits.
