Please ensure your correct model is selected

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.

    Ohlins Racing has a long history dating back to 1976 of providing premium motorcycle and automotive suspension systems to numerous racing teams, individual racers, and OE brands such as BMW Motorsport, Audi, Lamborghini. Pagani, Ducati and Kawasaki. Over time, thanks to extensive R&D, testing, and tuning, their products have evolved into some of the highest quality suspension systems in the world, providing years of flawless operation on both the street and the track. Ohlins' latest automotive suspension system, the DFV (Dual Flow Valve) Road and Track Coilover Kit, has bridged the gap between comfortable stock suspension and track focused coilover kits. These kits provide a ride that glides over typical bumps and dips in the road, all without the typical hard rattle and harsh feel of usual coilovers, and turn in tight and maintain tire grip and traction in corners significantly better than stock suspension ever could. This is all thanks to the spring rate chosen and Ohlins and their signature Dual Flow Valve. The DFV maintains comfort and agility by giving the same characteristics for both rebound and compression, allowing the wheel and tire to maintain constant contact with the road/track for maximum control. The Dual Flow Valve works by controlling shock fluid flow based on resistance and impact velocity. This is controlled in both compression and rebound, giving the quick shock operation that helps maintain traction. At low shaft travel speeds, oil flows mostly through the shaft jet bleed. At higher shaft speeds, oil flows mostly through the compression/rebound ports in the piston. At very high shaft speeds, or during sudden accelerations from potholes or large bumps in the road, oil can then escape through the ports in the DFV, absorbing a large amount of energy that would otherwise throw off the balance and control of the vehicle and keeping the tire planted firmly on the ground. With all three compression and rebound ports working together according to pressure and shaft speed, the result is the notorious premium suspension feel that only Ohlins can offer. In addition to managing the rebound and compression control, coilovers must also properly address heat changes in the shock oil. As the shock is pushed harder and longer, the oil quickly heats up due to friction and compression, and the oils flow characteristics change. The hotter the oil is, the easier it is for it to travel through ports and valves. To prevent this typical fade in control, Ohlins has implemented a temperature controlled needle bleed valve system that will expand as temperatures rise, slowly increasing restriction in the fluids flow through the valve gap. This produces a consistent dampening rate that maintains the vehicle's suspension characteristics lap after lap, turn after turn, no matter how hard you push your suspension's capabilities. Features: DFV (Dual Flow Valve) Adjustable ride-height Fully rebuildable Corrosion salt spray tested (ISO 9227) Includes hardware and installation instructions 2 year Limited Warranty Specs: Front Spring Rating: 400 lbs/in ( 7 kg/mm) Rear Spring Rating: 630 lbs/in ( 11 kg/mm)

    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. 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 (E46) Convertible / Coupe. Spring Rates (Default): Front: 8 kg/mm | Rear: 12 kg/mm. Construction: TIG-welded steel and CNC-machined aluminum. Adjustment Range: 3-Way Independent (Rebound / Low-Speed Compression / High-Speed Compression). Warranty: 1-Year manufacturer’s warranty against 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.

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.

    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.

    Bilstein's PSS10 coil over system combines adjustable monotube shock damper technology with front and rear height adjustments to give you everything you need in one package. The E46 PSS10 kit is one of the most impressive suspensions on the market for performance and quality. Bilstein has engineered this kit to be functional and specific to the E46 chassis and not overloaded with features and bullet points that you'll never use. With the PSS10 you get 10 damper settings with meaningful differences between clicks, ride height adjustment, TUV certified quality and performance, a limited lifetime warranty, and easy fitment with stock mounts and links.

    Bilstein PSS10 dampers feature their latest monotube design - a single large piston that performs better and lasts longer than other twin-tube designs. They also use a patented digressive valving system that helps give their shocks a better ride at any shock setting compared to competitor's progressive shocks. The PSS10 features 10 useful damper positions for rebound and compression - not hundreds of settings that you don't need or will never use. The settings range from 10 (softest) to 1 (stiffest) with meaningful variations between settings. This allows you to easily find a shock stiffness that best suits your driving environment and less wasted time trying separate adjustments and getting nowhere. The Bilstein PSS10 settings follow damper graphs and plots determined from their years of German performance tuning, including testing on the famed Nurburgring and Autobahn. Each setting is selected from a super-large knob at the bottom of each strut and shock - easily accessible from underneath the car. Each front strut is zinc coated for excellent wear resistance.

    This kit is designed to lower the car between 1.0" and 1.75" from the original stock, non-sport package suspension. This allows you to set your ride height to suit your personal tastes, lower the center of gravity and roll center, and for a more aggressive appearance. Bilstein supplies springs with a front progressiverate of 400lb and a rear progressive rate of 455lb. The progressive rate means the spring starts its compression at a softer rate but will quickly stiffen as the spring is compressed. This is ideal for street driving as the ride stays compliant over daily bumps and impacts while stiffening for more extreme cornering. Each spring is a 60mm ID so some hardware is already in place for a change to different springs. Front height adjustment is made via the perches on the coil over strut. The reat height is made from an adjustable perch mounted on top of the spring. The stock upper front strut mounts, rear upper shock mounts, and stock front sway bar links are used for installation. This keeps the cost low and installation easy! And it means replacement parts are easily obtained from multiple suppliers (not a kit-specific part that will be hard to source).

    The Bilstein PSS10 kit remains one of our favorite suspensions for an E46 simply because it works so well as an over-achieving street suspension. It's engineering greatly surpasses a regular shock/spring package and the quality surpasses many of the other aftermarket performance coil overs we see. This is our #1 choice for our customers who want a capable street suspension.

    The B16 PSS10 coilovers offer a stiffer spring rate than stock and a lower ride height for less bodyroll and better handling. These are among the easiest coil over kits on the market - no special mounts required (works with stock mounts and sway bar links), larger adjustment knob allows for easy shock damping changes, and coil over spanner wrenches included for easy height changes. Bilstein backs up their technology with a limited lifetime warranty. TUV approved for fitment, safety, and quality!

    Bilstein's monotube shock dampers in the PSS10 offer 10 precise settings for compression and rebound. A new setting is just a click away, allowing you to set a ride and handling combination that works for your setting. Instead of offering too many shock settings that you're never going to use, Bilstein has chosen ten optimal damping curves from a smooth street setting (P10) to an ultra-stiff track-only setup (P1). Shock changes are made from an easy-to-use over-sized adjuster knob.

    Ride height adjustments are done from perches that ride on each shock body, which are zinc coated for excellent wear and corrosion resistance. You can set the ride height between 0.5 to 1.3 inches lower than stock ride height. Springs are progressively rated so their initial compression rating is quite soft and then becomes stiffer as the spring compresses. These are stiffer than most coil over kit manufacturers and the results of Bilstein's extensive testing on the German Nurgburgring and Autobahn.

    The fitment of these is just like a standard shock and spring package. The front struts and rear shocks are compatible with the stock strut and shock mounts. You can re-use your own or choose a mount with additional features. Because the Bilstein design keeps the sway bar tab in the original location, you can re-use the stock sway bar links. Using the stock mounts keeps the cost and complexity down and allows for TUV certification. You can also be assured of the stock mount's quiet and long-lasting performance. The assembly of the front strut is the same as a the factory strut. In the rear, ride height is made by an adjustable spring perch that sits under the rear spring. Install instructions and diagrams included.

    If you're looking for a supremely capable and high quality suspension, then look no further than the Bilstein PSS10. It combines all of the best German engineering with real-world development, and a lifetime warranty.

    Fitment note: this system works only on cars not equipped with the factory EDC electronically adjustable shocks.

    Featuring:

    • Largest available piston diameter for greater sensitivity and precise control.
    • Patented digressive piston head design and deflective valving instantly reacts to changing road conditions.
    • 10-way adjustable dampening knobs that "click" from soft to hard with no tools or jacking required.
    • Monotube design dissipates heat more effectively than a twin tube shock for cooler, more efficient operation and longer life.
    • Weather resistant coating to resist oxidization, and ensure long life.
    • Lighter weight reduces wear and tear on suspension components.
    • Wrenches to adjust front and rear ride height included!

    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 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 H&R Coil Over kit takes the traditional shock/spring package one step further. H&R combines their progressive-rate springs with specially valved shocks and adds height adjusters that let you set the ride height to your own personal tastes. These coil overs are designed for street use with progressive rate springs that start out soft and stiffen as they are compressed. This helps to keep the ride compliant while still giving better handling and balance.

    H&R designs each suspension to work as a coil over. This means that the correct amount of travel has been built into each shock. And the shocks are valved specifically for the spring rates to give a tight and controlled ride without being harsh or ultra-stiff. Each H&R coil over is TUV tested and approved and meets ISO quality standards. These are used with the stock strut and shock mounts for a quick and easy install.

    For the E46 Convertible enthusiast who demands uncompromised feedback, the BC Racing RM Series offers a professional-grade solution. By moving the oil reservoir away from the wheel hub and brake components, the RM Series manages heat more effectively, preventing "damper fade" during long track sessions. The inclusion of front pillowball camber plates eliminates the compliant factory rubber bushings, providing direct and unmediated steering feel. Because convertibles often suffer from chassis flex, the RM Series' ability to maintain a flat cornering attitude through its stiff 12kg rear spring rate and robust inverted front struts makes it a transformative upgrade for the E46 platform. Key Features: Enhanced Thermal Management: Inverted layout moves fluid away from brake heat to maintain consistent damping performance. 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. TIG-Welded Durability: High-strength steel shock bodies with a black chrome finish for maximum corrosion resistance. Fully Rebuildable: Every component is 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. Damping Curve: Linear. Construction: Heavy-duty steel and 6061-T6 aluminum. Warranty: 2-Year limited warranty against manufacturer's defects.

    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.

    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.
