BC Racing 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.

For the E46 Convertible enthusiast looking to bridge the gap between a high-end street car and a dedicated race machine, the BC Racing ER Series offers uncompromised performance. By moving the secondary damping piston to the external canister, the system maintains its integrity under high-stress, high-temperature conditions. This is especially beneficial for the E46 Convertible, where the added 12kg rear spring rate helps counteract the platform's inherent weight distribution and chassis flex. The system features bearing-mounted spring platforms to eliminate the friction and "spring binding" often felt during tight steering maneuvers. Every ER Series kit is hand-assembled with precision and is fully rebuildable, ensuring it remains a long-term investment in the performance of your BMW. Key Features: Reduced Damping Fade: Strategic fluid placement keeps oil cooler, preserving valving accuracy during extended spirited driving. Camber Adjustable Top Mounts: High-quality aluminum plates eliminate the "mushy" feel of factory rubber bushings for direct driver feedback. Patented Concave Locking Ring: BC Racing’s unique design ensures lower mounts remain securely locked, even under extreme vibration. Customization Ready: Fully compatible with Swift Spring upgrades and custom valving tailored to specific tire or aero setups. Serviceable Construction: All components are individual and fully replaceable directly through BC Racing North America. Specifications: Vehicle Fitment: 2000–2006 BMW 3-Series (E46) Convertible (Excludes M3). Spring Rates (Default): Front: 6 kg/mm | Rear: 12 kg/mm. Spring Type: High-strength SAE9254 cold-wound steel. Construction: 304 Stainless Steel and 6061-T6 Anodized Aluminum. Warranty: 2-Year limited manufacturer's warranty.

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 DS Series for the E46 M3 Convertible is built using motorsport-grade materials designed to withstand the rigors of spirited driving and technical road courses. Because the E46 M3 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 hand-assembled and fully rebuildable, 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 M3 chassis to its limits. Key Features: Front Camber Plates: Precision-engineered aluminum alloy plates for surgical alignment and increased turn-in bite. Patented Locking Ring: Features a concave lower locking ring that prevents the system from vibrating loose even under track conditions. Bearing-Mounted Spring Platforms: Minimizes "spring binding" or popping during low-speed steering maneuvers. Fully Rebuildable: Every component, from the seals to the valving, is individual and replaceable for long-term serviceability. Customization Ready: Fully compatible with custom spring rates and Swift Spring upgrades for tailored track setups. Specifications: Vehicle Fitment: 2000–2006 BMW M3 Convertible (E46 Chassis). Spring Rates (Default): Front: 7 kg/mm | Rear: 12 kg/mm. Spring Type: High-strength SAE9254 cold-wound steel. Adjustability: Independent ride height, independent spring preload, and 30-way damping. 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.
