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.

For the E46 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 Convertible—which lacks the structural rigidity of its coupe counterparts—the ZX Series' advanced damping provides the stability needed to maintain a flat cornering attitude. The system features bearing-mounted spring platforms to eliminate "spring binding" or popping during tight maneuvers. Fully rebuildable and customizable, the ZX Series is a long-term investment in the competitive potential of your BMW. Key Features: Enhanced Thermal Management: External canisters keep fluid away from brake heat, maintaining valving accuracy lap after lap. Camber Adjustable Top Mounts: High-quality aluminum plates eliminate factory rubber "mush," providing direct, unmediated steering feedback. Independent Ride Height: Threaded bottom mounts allow for ride height changes without sacrificing suspension travel or preload. Patented Concave Locking Ring: BC Racing’s unique design ensures lower mounts remain securely locked, even under extreme track vibration. Custom Valving Available: Each kit can be custom-valved to match specific driver preferences or extreme aero/tire setups. Specifications: Vehicle Fitment: 2000–2006 BMW 3-Series (E46) Convertible (Excludes M3 models). Spring Rates (Default): Front: 6 kg/mm | Rear: 10 kg/mm (Swift Springs standard). Spring Type: Genuine Swift Springs for reduced unsprung weight. Piston Design: Linear Twin-Piston with remote canister valving. 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.

    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:

    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. Patented Concave Locking Ring: BC Racing’s unique design ensures lower mounts remain securely locked even under track conditions. Fully Rebuildable: All components are individual and replaceable, ensuring the long-term serviceability of the system. Specifications: Vehicle Fitment: 2000–2006 BMW M3 Convertible (E46 Chassis). Spring Rates (Standard): Front: 8 kg/mm | Rear: 12 kg/mm (Swift Springs). Hardware: Black chrome-plated steel shock bodies and 6061-T6 aluminum components. Adjustment Type: Independent ride height, spring preload, and 2-way damping. 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.

    BC Racing has made a name for themselves in the automotive enthusiast communities by developing adjustable, street-and-track capable coilover kits for over a decade that are not only highly effective but also don't break the bank! The BR Series coilover suspension kit features mounting points and brackets that are compatible with all stock mounting locations and components. It is their most popular and versatile suspension setup, offering linear springs (where possible), 30 levels of dampening adjustment including simultaneous compression and rebound control, and a 2-inch minimum ride height drop. All BR Series kits are Dyno tested to determine the best valving and spring rates for each chassis and are tested for a minimum of 6 months before being released to the public to ensure ride quality and reliability. All upper shock and strut mounts are constructed of 6061-T6 Aluminum to ensure a lightweight and incredibly strong design. Front design options include Caster/Camber Plates, Camber plates, and Rubber Mount Plates. See below for the option fitted to your chassis's BR Series Kit. The adjustable plate designs allow for up to 3 degrees of camber adjustment. The Rubber Mount Plates are better for preventing unwanted NVH. Lower shock mounts are either made of 6061-T6 Aluminum just like the top mounts (Fork or Bolt Eye Style Mount) that have been milled from a single piece of material, or high-quality STKM13C steel with all brackets welded robotically. Both styles are then powder coated for corrosion protection and styling. All springs used, linear, S-barrel, and v-barrel, are made of SAE9254 steel and utilize a Zinc coating under a powder coating finish to ensure rust cannot penetrate the metal of the spring and compromise performance or reliability. Liner springs are used in places possible unless otherwise limited by the OE design of the vehicle that does not allow it. In that case, S-Barrel or V-Barrel springs are used to match OE shape/style specifications and the spring's rate is then matched to the linear rate. BC Racing creates their kits utilizing a wide variety of shock types, lengths, and diameters. Each vehicle depending on their data from R&D, and accounting for the OEM suspension design will utilize a different style of shock. Each shock is hand assembled in their factory and dyno tested before use in their kits. Shocks are paired together by their compression and rebound numbers after dyno testing for even and precise quality and performance. Each shock body used in their system is 53mm for added strength, performance, and increased fluid capacity (unless limited spacing will not allow it). The shocks are then coated in black chrome for a clean, cohesive appearance and corrosion resistance. Specs and Features: 8k Front & 5k Rear Spring Rate S-Barrel front & Linear rear springs Valved specifically to spring style and rate Aluminum and Rubber Front Mounts Rear Rubber Mounts Black Powder Coated Components All OE style brackets and mounting for a perfect fit 30 Levels of Simultaneous Compression and Rebound Dampening 2-inch minimum and 3+ Inches of total potential drop Great for Track, Street, and any other conditions

    For the professional-level racer or the extreme enthusiast, the BC Racing ZR Series addresses the unique geometric and thermal requirements of the E46 M3 platform. By utilizing inverted front struts with a massive 42mm piston shaft, the ZR Series provides extreme structural rigidity, preventing geometry deflection under heavy braking and cornering loads. The 3-way adjustment allows the driver to "dial in" the car for specific obstacles; for instance, softening high-speed compression to soak up aggressive curbing while keeping low-speed compression firm for immediate turn-in response. Combined with standard pillowball top mounts, this system eliminates the "mushy" feel of factory rubber, providing direct, unmediated feedback to the driver. Key Features: Reduced Damper Fade: Remote external canisters move fluid away from hot brake components to ensure consistent lap times. Camber Adjustable Top Mounts: High-quality aluminum plates allow for aggressive track alignments to maximize the tire contact patch. Pillowball Rear Mounts: Replaces rubber bushings with solid spherical bearings 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.

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.
