BMW Coilovers for Street Use

There are several coilover options on the market - while a lot of this decision boils down to preference, we categorize coilovers as aEURoestreetaEUR based on price and comfort level. Coilovers in our street category will be comfortable enough to use on your daily driver, but perform well enough to handle occasional autocross days and light track use. These coilovers also won't break the bank. However, many of the options we have under street coilovers share many of the same features as our track coilovers, they often just utilize less durable materials and won't hold up as well to torcher testing.

    Looking for coilovers that will provide reliability on street driven vehicles but are also capable of feeding your weekend track demon's desire for performance? BC Racing's BR Series coilover kit may be just the thing for you.

    BR Series coilovers are the most popular and versatile option offered by BC racing, offering features such as 30-level dampening adjustment (simultaneous compression and rebound control), linear springs where possible, and a minimum of 2 inches ride height drop. To ensure performance, comfort, and quality, all BR Series kits are Dyno tested during the design stage to determine the best valving and spring rates, then installed and tested for a minimum of 6 months. This kit features mounts and brackets that are fully compatible with all stock mounting points and components.

    The upper shock/strut mounts are all constructed of 6061-T6 Aluminum for strength and weight savings. BC Racing design 1 of 3 types of upper mounts for each vehicle: Caster/Camber Plates (+/- 3* camber), Camber Plates (+/- 3* camber), and Rubber Mount Plates (NVH reduction). The included mount option for this kit is shown in the kit specs and features below.

    Lower shock mounts are powder coated for corrosion protection and constructed of either 6061-T6 aluminum that has been milled from a single piece (fork or bolt eye mount) or of STKM13C steel with all brackets welded robotically.

    The included springs come in one of 3 styles: linear, S-barrel, and V-barrel. Linear springs are used in most applications unless limited by the OE design that does not allow the use of linear springs. All spring options are made from SAE9254 steel and have a zinc coating applied under the powder coating for increased spring corrosion protection and long term reliability.

    All shock bodies used in the BR Series coilovers use a 53mm shock body (unless noted otherwise) for added strength, performance, and increased fluid capacity. All shocks are then powder coated black chrome for clean styling and corrosion protection.

    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 enthusiast who uses their F31 Touring as both a daily driver and a weekend track tool, the BC Racing RM Series provides unparalleled driver feedback. The inclusion of front pillowball camber plates as standard allows for aggressive alignment settings that sharpen turn-in and eliminate the "mushy" feel associated with OEM rubber mounts. By moving the oil reservoir away from the hub, the fluid stays cooler during spirited sessions, preventing the "damper fade" that often plagues standard suspension setups after consistent hard use. With the RM Series, the BMW F31 gains a level of poise and responsiveness typically reserved for dedicated M-cars. Key Features: Camber Adjustable Top Mounts: Pillowball front top mounts allow for precise camber adjustment and direct steering feedback. Reduced Damper Fade: Inverted layout keeps oil temperature more stable by increasing distance from hot brake components. Bearing-Mounted Spring Platforms: Minimizes friction between the spring and the perch to eliminate "spring binding" and popping. Patented Concave Locking Ring: Unique design ensures that once height is set, the lower mounts remain locked securely against vibration. Serviceable Design: Fully rebuildable with all replacement parts available directly from BC Racing. Specifications: Vehicle Fitment: 2012–2019 BMW 3-Series (F31) Touring / Wagon (3-Bolt Front Top Mounts). Spring Rates (Default): Front: 6 kg/mm | Rear: 10 kg/mm. Optional Rates: Custom springs (BC or Swift) available from 4kg to 20kg+ to suit specific builds. Construction: TIG-welded heavy-duty steel and anodized aluminum components. Warranty: 2-Year limited manufacturer's warranty.

    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!

    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 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 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.

    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 DS Series for the E46 Convertible is built using motorsport-grade materials designed to withstand the rigors of spirited driving and technical road courses. Because the E46 platform benefits greatly from increased front camber, this kit comes standard with front pillowball camber plates. These plates replace the compliant factory rubber mounts, providing unmediated feedback to the driver and allowing for aggressive alignment settings to maximize tire contact patches. Every DS Series kit is fully rebuildable and customizable, with the option to upgrade to Swift Springs for even more consistent spring rates and reduced weight. Whether you're carving canyons or attending a weekend track day, the DS Series provides the stability and feedback needed to push the E46 chassis to its limits. Key Features: Front Camber Plates: Precision-engineered aluminum plates for surgical alignment and increased turn-in bite. Satin Chrome Finished Shock Body: A highly durable coating that resists the elements while providing a high-end look. Linear Spring Piston: While the valving is digressive, the springs remain linear to provide a predictable and consistent feel. Fully Rebuildable: Every part, from the seals to the valving, is serviceable and replaceable. Custom Spring Rate Compatibility: Can be ordered with custom valving paired specifically to your requested spring rates. Specifications: Vehicle Fitment: 2000–2006 BMW 3-Series (E46) Convertible (All models except M3). Spring Rates (Default): Front: 6 kg/mm | Rear: 8 kg/mm. Optional Rates: Custom rates available (e.g., 8kg/10kg) for more track-oriented setups. Piston Diameter: 46mm. Adjustability: Ride height, spring preload, and 30-way damping.

    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!
