The BEST Coilovers Available Today for Your BMW M.
Motion Control Suspension's motorsport bred race dampers have proven to be up to 3 seconds faster on track over the OEM damper package with our own data. We have set record after record in BMW's and Porsche's with these dampers and in our opinion, there's nothing better out there. Here are just a few benefits of these dampers:
- Bred in motorsport. The team at MCS have won every big race in GT car racing and then some. Including 24hr LeMans, 24hr Daytona and Nurburgring 24
- Increase in mechanical grip and driver confidence means faster lap times
- Bespoke packages customizable to your car and your needs. No one size fits all here unless you want it
- Superior parts, design and adjustability mean more comfortable for street driving than OEM setups and faster on track in the same package
- More robust and typically longer lasting than OEM dampers and, completely rebuildable
- Completely adjustable for different tracks, canyons or comfort on the street
- Made, assembled and serviced in the U.S.A. No more calls to Europe or Asia at odd hours trying to get answers and service requests
- The best support and service available. Period.
- We keep inventory of MCS systems and typically ship in stock damper sets within 1 business day!
Completely Personal, Just For You.
Unlike most shock manufacturers on the market, MCS understands that not all cars and drivers are the same or need the same things. Instead of sending out prebuilt kits that may not be exactly what you're looking for, these are completely customizable in every way. Spring rates, nitrogen pressures, even custom valving* are available for you if you want, and that's where we come in. We provide consultations to make sure that each kit is assembled with you in mind. Just pick "Custom" in the Assembly drop down menu and make sure you include your email and phone number at check out and we'll reach out to make sure these are perfect for you.
Ready To Ship Options Available Too
Don't know exactly what you want? No problem! Our packaged damper sets make it easy with one simple answer in our dropdown "Assembly" menu. Pick between a street/track option and our "RWE Spec" track focused option. Don't worry, both are incredible and we have lap records with both standard setups. All assemblies include our spec Swift main & helper springs, Vorshlag front camber plates and MCS rear clevis. See the different kit definitions below.
Bonus
We keep all common damper kits IN STOCK and ready to ship or assemble with a variety of different springs rates within 1 business day of order. Order one of our complete kits and we'll ship you a completely assembled and ready to bolt on damper kit, torqued to spec and paint marked ready to go.
Bare Dampers: Just the dampers and basic spring seat hardware. Free to source anything else you want.
Street/Track: Great for all around driving, prioritizing comfort on road but plenty capable on track. Proving the point, this lap was completed on our "Street/Track" set up:
RWE Spec: Is your car a track dedicated car? Do you make the most out of faster R-comp or slick tires? Frequent faster, smoother tracks? This is the package for you. The best part? Still very comfortable on the street
Note: We typically sell every MCS damper system as a coilover rear. The same dampers can be used as a divorced setup if desired, just pick this option in the drop down. Contrary to what you may have read on the forums, you do not need to tie a cage into the rear shock towers to safely run this set up on E9X, F8X and G8X chassis. Reinforcement load plates for the E36/E46's to assist them are required. Of the thousands of MCS's we have assembled, we have never had an issue with any C/O rear, including all of our race cars running very high spring rates, slick tires, massive cornering and acceleration loads, aero or any other factor that could contribute to an issue.
*Custom valving options are custom ordered and are subject to 3-6 week wait times depending on the time of year.
ATTENTION: Front endlinks are required. We used to include them but we found many people requesting to remove them as they already had sets for their car. If you don't have them they are available HERE.
Important: C/O Rear May Experience a slight "Squeak" from the rear with certain sway bar types with spring contact. This is superficial and is perfectly ok for track use. If you are sensitive to light noises, select "Divorced" from the drop down.
YAW Sensor: Being race dampers, these do not have provisions for the factory YAW sensors. Commonly, everyone wire ties these to the damper bodies or coded them out to avoid the error messages in the iDrive/dash. We have made shock body clamps that mount the sensor in the correct location for a complete and "finished" looking install. We include these, again free of charge, whenever you buy a set of F8X MCS's from us.
How Do I Choose?
