BMW Coilovers

Coilovers provide more adjustability than a strut and spring setup and can serve a variety of different needs - it's important to be sure of what your suspension goals are. We have broken down our coilover catalog into street and track categories, this is not to say you can't use one of our aEURoestreetaEUR coilovers on the track, or vice versa, but it is to give you a starting point. Are you someone who is interested in getting your BMW lower than factory height for the aesthetic value and handling benefits in a daily driver? Check out our street category. The majority of these are priced to avoid breaking the bank, but providing a good value in terms of features and benefits. On the other hand, if you are putting together your vehicle with the track as its main purpose, take a look at our track coilovers category. We have hand selected these coilover brands as being more expensive coilovers built to hold up to abuse.

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 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.

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 Coilovers use a proprietary digressive piston design that offers the driver increased damping force at low-speed piston velocities while maintaining a linear damper feel at higher piston velocities. One of the greatest advantages of increased low-speed damping force relates to what the driver feels, e.g., roll, pitch, dive, and quick weight transitions on technical road courses. You will notice a much more planted and confident chassis feel, with increased feedback through the steering wheel. To evoke the passion for driving that all automotive enthusiasts have embedded in their DNA, BC Racing took the best features from Their BR Series Coilover, engineered components to improve driver experience, conducted in-house testing, approved the product, determined a reasonable, affordable price, and proudly present the BC Racing DS Series Coilover for 350+ vehicles, from the Toyota Camry to the Nissan GT-R and beyond, BC Racing has a DS Series Coilover system for you. The DS Series is available for a vast number of vehicles and with that, an equal number of customization options as well. The BC Racing DS Series Coilover can be customized for every type of racing imaginable, from the weekend track warrior to the full-time race car.

    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 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.

    For the E46 M3 Convertible enthusiast looking to bridge the gap between a high-end street car and a dedicated race machine, the BC Racing ZX Series offers an unparalleled engineering approach. By moving the compression valving to the external canisters, the system maintains its integrity under high-stress, high-temperature conditions, effectively eliminating "damper fade." For the E46 M3 platform—especially the convertible which requires higher roll stiffness to compensate for chassis flex—the ZX Series' 12kg rear spring rate and advanced damping provide the stability needed to maintain a flat cornering attitude. The system features standard front pillowball camber plates to eliminate factory rubber "mush," providing direct and unmediated steering feedback to the driver. Key Features: Enhanced Thermal Management: External canisters keep fluid away from brake heat to maintain valving accuracy lap after lap. Camber Adjustable Top Mounts: High-quality aluminum alloy plates allow for aggressive track alignments to maximize the tire contact patch. Pillowball Rear Mounts: Replaces rubber bushings with solid spherical bearings (on applicable kits) for increased response and precision. Patented Concave Locking Ring: BC Racing’s unique design ensures lower mounts remain securely locked, even under extreme track vibration. Fully Rebuildable: Every component is individual and replaceable, making this a long-term investment in the car's competitive potential. Specifications: Vehicle Fitment: 2000–2006 BMW M3 Convertible (E46 Chassis). Spring Rates (Default): Front: 8 kg/mm | Rear: 12 kg/mm (Swift Springs standard). Piston Design: Linear Twin-Piston with remote canister valving. Adjustment Range: 3-Way Independent (Rebound / Low-Speed Compression / High-Speed Compression). Warranty: 1-Year limited manufacturer's warranty.

    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.

    For the E46 M3 Convertible owner who demands uncompromised geometry control, the BC Racing HM Series offers a motorsport-first engineering solution. By utilizing an inverted strut layout with a much larger internal piston shaft, the HM Series excels in maintaining wheel alignment during extreme lateral cornering—a critical factor for the MacPherson strut-equipped M3. The addition of external reservoirs ensures the damping fluid remains cool, preserving valving accuracy lap after lap. Standard front pillowball camber plates eliminate factory rubber "mush," providing direct and unmediated steering feedback. Because convertibles often require higher roll stiffness to compensate for chassis flex, the HM Series’ 12kg rear spring rate provides the stability needed to keep the car planted and responsive. Key Features: Enhanced Side-Load Resistance: The inverted design handles high lateral loads longer than traditional upright dampers without fatigue. Reduced Damper Fade: External canisters move fluid away from brake heat to maintain consistent lap times. Camber Adjustable Top Mounts: Precision-engineered aluminum plates allow for surgical alignment and increased turn-in bite.

    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.

Individual customization can be achieved in 16 precise click positions, allowing you to choose between more comfort or more body control. The two-step patented TVR-A technology allows the damper oil to flow through an adjustable, conical low-speed valve during slow piston speeds, while during higher piston speeds the main rebound stage valve opens to handle the flow of large volumes of oil. This provides a major improvement in ride comfort without influencing the high-speed in the safety-relevant zone. Two-Step Compression Stage Valve with Low and High-Speed KW TVCLH-A Adjustment Technology This is the high-end motorsports technology for the most demanding street and track performance customers. Two separate valves and a two-way adjustable compression stage valve allow separate compression damping changes in the low and high-speed range. The adjustments are made via two adjustment dials with click increments that feature 16 settings (with 15 clicks) in the high-speed valve housing and 7 settings (with 6 clicks) in the low-speed housing. During tuning at the KW drive dynamics test facility, the groundbreaking V4 coilover suspension is tuned to a mid-level basic setting for the best road performance with an additional recommended setting for occasional track day use. The 3A Clubsport coilover suspension is tuned to a mid-level factory setting especially for track day use, with an additional recommended setting for the drive to the race track. Starting from the factory setting, the damping can be set firmer or softer for low and high-speed. External Reservoir The use of KW reservoirs provides additional volume for additional oil and additional cooling capacity for extremely high-performance setups. The reservoir is filled with low gas pressure and can be fitted anywhere and accommodates the adjustable compression stage valve to provide the damper with more working space. Additional Features: Uniball Top Mount Trapezoidal Threads Stainless Steel Innox Construction Composite Spring Seats
