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.

Adjustable Rebound & Compression Damping

Want full control? The KW V3 gives you multiple settings for both rebound and compression. You have full access over ride comfort and handling to dial in that perfect setup. Race teams rely on adjustments to get that perfect lap time and having shock controls at your fingertips is key. KW V3 features -
  • Separate adjustments for compression (14 positions) and rebound (infinite settings),
  • Stiffer springs over stock for less bodyroll than the standard suspension,
  • Stainless steel strut/shock bodies and composite spring perches for superior corrossion resistance,
  • Individually height-adjustable - Front = 10-35mm lowering; Rear = 5-35mm lowering,
  • TUV approved lowering range and operation,
  • Expert engineering and design for ease-of-use and long durability,
    Whether you track the car often or only use it for backroad carving the V3 will give you the tools to set up an ideal handling condition. You can crank it up for smooth and fast surfaces or soften it for city or rough roads. Since each shock is 2-way adjustable you can alter the front-rear balance to account for brake dive or squat during power application coming out of the corner. You are in total control!

    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.
    EDC must be disabled using the KW EDC Cancellation Kit available from the menu below. Cars without EDC do not require the Kit.

With the KW DDC button, the respective driving mode, Comfort, Sport, or Sport+ can be selected changing the adaptive KW DDC ECU coilover kit damper setting within milliseconds. In Sport+ mode, the adaptive KW dampers give every car an unadulterated driving behavior. A setup which is ideal for demanding rides on twisty roads with lots of load changes. The Sport mode, however, is perfect for driving on the highway with long curves, while the Comfort mode is the ideal for traveling on poorly developed roads. In Comfort mode, the suspension adjusts automatically to the respective driving situation. You are not buying a mass-produced, generic coilover kit, a KW coilover has been developed specifically for your particular vehicle. As a manufacturer, KW uses only its own resources, high-quality components and the damper technology that has all developed in-house. With the KW DDC coilovers, the rolling motion of the body will be reduced during compression giving you the benefit of more direct handling and confidence while driving.

    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 extremely effective, but also don't brake the bank! 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 RM series feature high quality damping adjustable monotube inverted dampers at the front or front and rear, depending on vehicle. The RM coilovers offer the majority of the features of the BR series but with the additional benefit of the inverted damper unit. Inverting the damper unit brings with it a number of advantages. The large 42mm damper rod and inverted design gives the inverted damper units much greater strength and resistance to side loadings. By reducing flex the RM inverted units lead to more consistent steering geometry resulting in more predictable and responsive handling. 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 aluminum components (top mounts, locking collars etc.) are anodized 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 Inverted Mono-Tube Damper Linear Piston And Damping Curve Height Adjustment Independent Of Spring Compression 30-Clicks Of Simultaneous Compression/Rebound Adjustment Front Camber Plates Standard On Applicable Kits Rear Camber Plates Available For Applicable Kits Custom Spring Rates And Swift Spring Compatible Custom Valving Or Valving Paired For Custom Spring Rates 1-Year Warranty Against Manufacturers Defect Fully Rebuildable NOTE: LEAD TIMES WILL BE 4-8 WEEKS.

    Adjustable Rebound Damping

    The KW Variant 2 gives shock rebound control to give you more options in fine-tuning the handling of the car. The V2 includes the same features of the V1 kit, including -
  • Adjustable Rebound with fixed compression settings - optimal ride comfort then dial in more grip and a better balance with less bodyroll than the standard suspension,
  • Stainless steel strut/shock bodies and composite spring perches for superior corrossion resistance,
  • Individually height-adjustable - Front = 25-55mm lowering; Rear = 35-60mm lowering,
  • TUV approved lowering range and operation,
  • Expert engineering and design for ease-of-use and long durability,
    This kit is an excellent compromise between a fully-adjustable V3 suspension and the basic V1 street kit. It's great for someone who does not want to make complicated and time-consuming shock adjustments. Just dial in the rebound for more grip and less body motions. Set it back for a compliant street ride.

    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.

    A coilover is a suspension system that combines a shock absorber with a coil spring wrapped around it. This setup has become widely popular in the automotive aftermarket due to its ability to offer a lower ride height and excellent handling compared to standard shocks.

    The KW V3 coilovers stand out with their dual dampening technology, making them suitable for both street and track use. With separate adjustments for rebound and compression dampening, drivers can fine-tune their suspension setup for optimal handling and performance. The patented two-stage valve system allows adjustments for comfort (rebound damping) and driving dynamics (compression damping) in the low-speed range while maintaining fixed settings for high-speed control for enhanced driving safety.

    Key Features of the KW V3 Coilovers:

    Dual dampening technology with separate rebound and compression adjustments Stainless Steel "Inox-Technology" for durability TüV-approved lowering range High-quality components for long-lasting performance Infinitely variable rebound damping adjustment 14-way adjustable compression damping Unique and precise damping force adjustment Comprehensive documentation for easy installation and setup This V3 coilover system is compatible with all X3M/X4M models and comes with an EDC-cancellation kit to prevent warning lights and drivetrain malfunctions after installation.

    KW was founded in 1995, employing only three employees and selling their systems to a small market. Today, KW is represented everywhere and has approximately 200 employees in five locations. KW is currently the epitome of premium components in suspension tuning and refinement. KW offers its customers the largest suspension program worldwide and each component is tested using their state-of-the-art seven-post drive dynamics test.

    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 = 35-65mm lowering; Rear = 35-65mm 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 an E46 Xi 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.

    Fitment Note: Wheel spacers may be required depending on wheel/tire sizing and ride height setting.

    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. Swift Springs are available upon request with your choice of rates and matched or custom valving.

The rebound adjustment is externally adjustable via an adjustment spindle at the top of the shock.

    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 body roll than the standard suspension, Stainless steel strut/shock bodies and composite spring perches for superior corrosion resistance, Individually height-adjustable (Front & Rear Lowering: 1.2"-2.0") 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 BMW owner who does not plan on tracking or autocrossing the car often and mainly 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.

    Experience the innovation and quality of high-end engineering: the KW DDC (Dynamic Damping Control) ECU (Electronic Control Unit) coilover suspension, made in Germany. For the first time with its electronically adjustable dampers, the KW DDC ECU coilover system combines intelligent, app-controlled suspension tuning with ride height adjustability. This gives you the opportunity to upgrade your vehicle with an adaptive damper systen and electronically control the level of performance or comfort that meets your requirements Included in the package is a KW “inox-line” coilover suspension with high-quality stainless steel struts, electronically adjustable dampers, a high-performance control unit with a vehicle-specific set of cables, a KW DDC control button giving you control from the comfort of the drivers seat, and elaborate assembly instructions for an easy installation. The KW DDC ECU Coilover suspension features three vehicle-specific damper setups. At the touch of a button, you can choose between the basic Sport setting, a very sporty and performance-oriented Sport+ setup or Comfort mode. With the KW DDC button, the respective driving mode, Comfort, Sport, or Sport+ can be selected changing the adaptive KW DDC ECU coilover kit damper setting within milliseconds. In Sport+ mode, the adaptive KW dampers give every car an unadulterated driving behavior. A setup which is ideal for demanding rides on twisty roads with lots of load changes. The Sport mode, however, is perfect for driving on the highway with long curves, while the Comfort mode is the ideal for traveling on poorly developed roads. In Comfort mode, the suspension adjusts automatically to the respective driving situation. You are not buying a mass-produced, generic coilover kit, a KW coilover has been developed specifically for your particular vehicle. As a manufacturer, KW uses only its own resources, high-quality components and the damper technology that has all developed in-house. With the KW DDC coilovers, the rolling motion of the body will be reduced during compression giving you the benefit of more direct handling and confidence while driving. Height Adjustment Range: Front: 1.2 - 2.4" Rear: 0.8 - 2.0"

    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

    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.

    BC Racing's HM Coilover system offers the same great benefits of the RM Series with the addition of 2 way damping adjustment. Each HM Coilover system features inverted mono-tube dampers with independently adjustable compression and rebound. The inverted damper design moves vital damper fluid away from detrimental heat sources to avoid overheating which can cause damper fade under extreme track use. Know your safe from the elements! The damper units are black chromed steel to give superb durability even through the darkest of European winters. The aluminum components (top mounts, locking collars etc.) are anodized 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: Engineered for 100% track use * 30 levels of separate rebound and compression adjustment * Inverted damper design (depending on models) * Dual Piston design (1 res., 1 in shock) * Teflon coated steel braided lines for external reservoir on inverted dampers and solid stem for double A-arm cars Custom spring rates available * Completely rebuildable * Monotube damper design * Patented concave lower locking collar * 1 year manufacturer warranty NOTE: LEAD TIMES FOR ALL NEW ORDERS ARE 4-8 WEEKS.

    For the E46 Convertible owner looking to overcome the platform's inherent chassis flex and maximize track performance, the BC Racing HM Series offers a motorsport-first engineering approach. By utilizing an inverted strut layout and a high 12kg rear spring rate, the HM Series provides uncompromised geometry control under heavy cornering loads. The 2-way independent adjustment allows the driver to fine-tune high-speed stability and low-speed turn-in separately, which is critical for balancing a convertible's unique weight distribution. Every HM Series kit is hand-assembled with TIG-welded 304 stainless steel and 6061-T6 aluminum components, ensuring a system that is as durable as it is fast. Key Features: Enhanced Thermal Stability: External canisters move the fluid away from brake heat to maintain valving accuracy. Linear Twin-Piston Design: Provides a large surface area for precise and predictable damping response. Camber Adjustable Top Mounts: Precision-engineered aluminum plates eliminate factory rubber compliance for direct steering feedback. Independent Ride Height: Threaded shock bodies allow for height adjustment without sacrificing damper stroke or spring travel. Fully Rebuildable: All components are individual and replaceable, ensuring the long-term serviceability of the system. Specifications: Vehicle Fitment: 2000–2006 BMW 3-Series (E46) Convertible (Excludes M3). Spring Rates (Default): Front: 6 kg/mm | Rear: 12 kg/mm. Piston Design: Linear Twin-Piston. Construction: 304 Stainless Steel and Anodized 6061-T6 Aluminum. 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.

    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 Convertible owner who demands uncompromised feedback during spirited driving or track sessions, the BC Racing RM Series offers a professional-grade motorsport approach. By moving the fluid reservoir away from the wheel hub and brake components, the RM Series manages heat more effectively, preventing damper fade during prolonged high-speed sessions. The inclusion of front pillowball camber plates replaces compliant factory rubber bushings, providing direct and unmediated steering feel. Because convertibles often require higher roll stiffness to compensate for chassis flex, the RM Series' default 12kg rear spring rate provides the stability needed to keep the E46 M3 planted and responsive through tight technical sections. Key Features: Reduced Damper Fade: Inverted layout keeps oil temperature more stable by increasing distance from hot brake components. Camber Adjustable Top Mounts: Precision-engineered aluminum plates allow for aggressive alignment specs to maximize front-end grip. Patented Concave Locking Ring: Unique design ensures that once ride height is set, the lower mounts remain locked securely against vibration. Linear Piston Architecture: Provides a predictable and consistent damping feel for better driver confidence at the limit. Fully Rebuildable: Every component is individual and 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. Optional Upgrades: Compatible with custom spring rates and Swift Springs (+2kg/-2kg range on standard valving). Finish: Black chrome-plated steel bodies for maximum corrosion resistance. Warranty: 2-Year limited warranty against manufacturer's defects.

    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.
