The ER Series coilovers bring with them the high quality and unique features seen on the BR and RM type but have the additional benefit of external reservoirs and the ability to allow the end user to individually adjust and set compression and rebound damping rates. By separating the adjustment for damping compression and rebound the ER Series allows you to dial the vehicle in to your exact needs. When braking hard whilst approaching a corner you want the car to transfer weight to the front tires to maximize grip for the braking effort and also to allow you to trail brake into the corner without the car understeering. Ride height adjustment: Ride height is determined by the position of the coil over bottom mount. The mount can be wound up and down the damper body to give a full range of adjustment. Because ride height is determined by an adjustable bottom mount rather than spring platform you retain full damper travel regardless of the ride height run. Know your protected from the elements! The damper units are black chromed steel to give superb durability even through the darkest of European winters. The aluminium components (top mounts, locking collars etc) are anodised and the steel lower mounts go through an electrophoretic disposition process followed by powder coating. A random selection of steel components (brackets, dampers, screws etc) are put through a salt spray test once a month to check the quality of the protective processes and that anti corrosive properties are kept at the highest possible standard. Features: Highly Customizable Mono-Tube Damper Linear Twin-Piston Design Height Adjustment Independent Of Spring Compression 30-Clicks Of Compression Adjustment Via The External Reservoirs 30-Clicks Of Rebound Adjustment From The Top Of The Damper Front And Rear Camber Plates Standard On All Applicable Kits Front And Rear Pillowball Mounts Standard When Camber Plates Do Not Apply Custom Spring Rates And Swift Spring Compatible Custom Valved To Match The Drivers Requested Spring Rates Swift Spring Upgrade Available On Most Applications 1-Year Warranty Against Manufacturers Defect Fully Rebuildable NOTE: LEAD TIMES ON ALL NEW ORDERS 4-8 WEEKS

The BC Racing RM Series Coilover System uses a mono-tube inverted damper in the front and rear of vehicles that use McPherson style OEM strut suspension. On vehicles that use front struts only, BC Racing provides an inverted front strut and then provides an upright BR Series damper for the rear. Inverted dampers are useful in decreasing unsprung weight by moving the greatest mass of the strut to the top where it connects to the sprung weight of the chassis, where weight can be more easily shaved. The BC Racing RM Series Coilover System uses a much larger inverted piston shaft that can handle higher lateral loads for longer periods of time without fatigue. These higher lateral loads are only prevalent on McPherson style strut suspension, not on Double A-Arm vehicles.

The BC Racing HM Series Coilover System gets its great qualities from a combination of two previous BC Racing Coilover Systems - the RM Series and ER Series. The HM Series uses an inverted mono-tube damper, just like the RM Series, but adds the independent compression and rebound adjustment of the ER Series. Each HM Series Coilover System uses inverted mono-tube dampers front and rear on McPherson strut vehicles with steel braided lines leading from the top of the damper to the external reservoirs. The external reservoirs allow for a higher oil capacity with the added benefit of increased thermal dissipation, they also house the secondary damping piston. For Subarus and other McPherson suspension vehicles that are heavily tracked, the BC Racing HM Series Suspension System is definitely worth checking out!

For the E46 M3 enthusiast looking to bridge the gap between a high-end street car and a dedicated race machine, the BC Racing ER Series offers a "motorsport-first" engineering approach. By moving the secondary damping piston to the external canister, the system maintains its integrity under high-stress conditions. This is especially beneficial for the M3 Convertible, where the high 12kg rear spring rate helps counteract the platform's inherent weight and chassis flex, providing a flat and predictable cornering attitude. The system includes front pillowball camber plates as standard, eliminating the compliant factory rubber bushings to provide direct, unmediated steering feedback and allowing for aggressive track-ready alignment settings. Key Features: Reduced Damping Fade: External canisters keep fluid cooler by increasing the distance from hot brake components. Camber Adjustable Top Mounts: Precision-engineered aluminum plates allow for surgical alignment and increased turn-in bite. Patented Concave Locking Ring: BC Racing’s unique design ensures lower mounts remain securely locked, even under extreme vibration. Linear Piston Architecture: Provides a predictable and consistent damping feel for better driver confidence at the limit. Serviceable Construction: All components are individual and fully replaceable, ensuring the long-term serviceability of the system. Specifications: Vehicle Fitment: 2000–2006 BMW M3 (E46) Convertible / Coupe. Spring Rates (Default): Front: 8 kg/mm | Rear: 12 kg/mm. Spring Type: High-strength SAE9254 cold-wound steel. Construction: Black chrome-plated steel bodies for maximum corrosion resistance and anodized 6061-T6 aluminum. Warranty: 1-Year limited manufacturer's warranty.

The DS series from BC racing offers increased control and feedback for those looking to achieve the best driving experience possible. Digressive Valving means the shock is firmer at low speed, while transitioning to a softer and more linear feel as (shaft) speed increases. This leads to a much more planted and controlled feeling in the chassis, increased feedback through the wheel, and a slight drop in passenger comfort.

For the F31 Touring owner looking to dominate the track while maintaining a refined street presence, the BC Racing ER Series offers a "motorsport-first" engineering approach. The inverted-style front struts (on applicable MacPherson designs) and external canisters move the weight of the fluid away from the hubs, reducing unsprung weight and improving the suspension's ability to react to high-speed road imperfections. The system includes bearing-mounted upper spring platforms to eliminate spring "binding" or popping during tight maneuvers. With its massive range of adjustability and robust build quality, the ER Series transforms the F31 wagon into a highly capable, predictable, and remarkably fast track machine. Key Features: Reduced Unsprung Weight: Strategic component placement allows the wheels to track road surfaces more effectively for increased grip. Advanced Damping Control: 30 clicks of compression (on the reservoir) and 30 clicks of rebound (on the shock top) for 900 possible damping combinations. Pillowball Top Mounts: Eliminates the "mushy" feel of factory rubber bushings, providing direct and unmediated feedback to the driver. Concave Lower Locking Ring: BC Racing's patented design prevents the lower mounts from vibrating loose even under extreme track vibration. Serviceable Design: All components are individual and fully replaceable, making the system a long-term investment for the life of the vehicle.

Factory Pre-set Damping

The Variant 1 is KW's basic simple and effective coil over kit that is still packed with lots of features -

Pre-set damping optimized for a blend of ride comfort and handling with less bodyroll than the standard suspension,

Stainless steel strut/shock bodies and composite spring perches for superior corrossion resistance,

Individually height-adjustable - Front = 25-50mm lowering; Rear = 30-55mm lowering,

TUV approved lowering range and operation,

Expert engineering and design for ease-of-use and long durability,
This is the ideal coil over kit for a F31 328i xDrive Wagon owner who does not plan on tracking or autocrossing the car and just wants a lower, more aggressive stance and better handling. KW has set the shock damping rates to be an excellent balance for a smooth yet taut ride, and to resist bodyroll motions for better handling. The Variant 1 differs from the Street Comfort set in that it has stiffer springs and revised shock settings. If you want a sportier ride and better handling than stock the Variant 1 is an excellent choice.

Coil over suspensions are better engineered suspension options compared to a standard shock + spring package. Since the springs and shocks in a coil over are designed by a team of engineers to work together, there is much better suspension travel and more precisely tuned specifications for spring and shock rates. Using separate shock and spring specs may result in premature coil bind or shock bottoming. And most coil over kits offer more features than the traditional packages. Coil overs are also more useful when larger wheels/tires are used because you can precisely set the ride heights to clear the new tires.

Fitment Note: Wheel spacers may be required depending on wheel/tire sizing and ride height setting.
Cars with the factory EDC electronic adjustable shocks must have the system disabled with the optional KW EDC Cancellation Kit (or similar). This is a direct fit for cars without EDC.

Lifetime warranty!

These KW Variant 1 coil overs fit the following BMWs:

The BC Racing HM Series Coilover System gets its great qualities from a combination of two previous BC Racing Coilover Systems - the RM Series and ER Series. The HM Series uses an inverted mono-tube damper, just like the RM Series, but adds the independent compression and rebound adjustment of the ER Series. Each HM Series Coilover System uses inverted mono-tube dampers front and rear on McPherson strut vehicles with steel braided lines leading from the top of the damper to the external reservoirs. The external reservoirs allow for a higher oil capacity with the added benefit of increased thermal dissipation, they also house the secondary damping piston. For Subarus and other McPherson suspension vehicles that are heavily tracked, the BC Racing HM Series Suspension System is definitely worth checking out!

The DS series from BC racing offers increased control and feedback for those looking to achieve the best driving experience possible. Digressive Valving means the shock is firmer at low speed, while transitioning to a softer and more linear feel as (shaft) speed increases. This leads to a much more planted and controlled feeling in the chassis, increased feedback through the wheel, and a slight drop in passenger comfort.

Designed for racers ranging from novice to pro, the BC Racing ZR Series addresses the unique weight distribution and chassis requirements of the E46 Convertible. The inverted front struts utilize a massive 42mm piston shaft, providing a rigid backbone that prevents geometry deflection under heavy braking and high-G cornering. By separating low-speed and high-speed compression, drivers can stiffen low-speed damping to eliminate body roll and pitch during turn-in while keeping high-speed damping compliant enough to absorb track curbing without upsetting the chassis. Every ZR kit is hand-assembled with TIG-welded steel and anodized 6061-T6 aluminum, providing a professional-grade motorsport component that is fully rebuildable and customizable. Key Features: Enhanced Low-Speed Damping: Specifically tuned to stabilize the E46’s heavier convertible chassis during quick weight transitions. Thermal Management: Remote-mounted external reservoirs move fluid away from hot brake components to ensure consistent lap times. Camber Adjustable Top Mounts: High-quality aluminum plates eliminate factory rubber "mush," providing direct, unmediated steering feedback. Bearing-Mounted Spring Platforms: Minimizes friction between the spring and perch to eliminate "spring binding" during tight steering. Industrial Corrosion Protection: Black chrome-plated steel shock bodies and electrophoretic disposition on steel mounts ensure a long service life. Specifications: Vehicle Fitment: 2000–2006 BMW 3-Series (E46) Convertible (All models except M3). Spring Rates (Standard): Front: 6 kg/mm | Rear: 10 kg/mm (Swift Springs). Piston Design: Linear Twin-Piston (Standard on 3-way kits). Weight: Approx. 23 kg (Full Kit). Warranty: 2-Year limited manufacturer's warranty.

The BC Racing RM Series Coilover System uses a mono-tube inverted damper in the front and rear of vehicles that use McPherson style OEM strut suspension. On vehicles that use front struts only, BC Racing provides an inverted front strut and then provides an upright BR Series damper for the rear. Inverted dampers are useful in decreasing unsprung weight by moving the greatest mass of the strut to the top where it connects to the sprung weight of the chassis, where weight can be more easily shaved. The BC Racing RM Series Coilover System uses a much larger inverted piston shaft that can handle higher lateral loads for longer periods of time without fatigue. These higher lateral loads are only prevalent on McPherson style strut suspension, not on Double A-Arm vehicles.
