For the 2022+ BMW X1 owner looking for a robust and durable suspension upgrade, the BC Racing BR Series provides a "no-compromise" approach to build quality. The shock bodies are manufactured from TIG-welded heavy-gauge steel with a black chrome finish for maximum corrosion resistance, while the locking collars and top mounts are crafted from anodized 6061-T6 aluminum. This kit features high-strength SAE9254 cold-wound steel springs, designed to withstand rigorous use without losing their rate. By moving from factory rubber-isolated struts to a precision-valved coilover, the X1 gains sharper turn-in, reduced pitch during braking, and a significantly more connected feel to the road, transforming the SAV's driving dynamics into a more car-like experience. Key Features: Customization Options: Compatible with custom spring rates and Swift Spring upgrades for tailored track or heavy-load setups. In-House Testing: Each kit is extensively track-tested and refined to ensure the best possible balance for the U11 chassis. Bearing-Mounted Spring Platforms: Minimizes "spring binding" or popping noises during low-speed steering maneuvers. Patented Locking Ring: Features a concave lower locking ring that prevents the system from vibrating loose even under track conditions. Corrosion Protection: Finished in black chrome and anodized aluminum for durability in all weather conditions. Specifications: Vehicle Fitment: 2022+ BMW X1 (U11) AWD / xDrive.

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.

Step up to a real coilover system without blowing the budget with the BC Racing BR Series. Developed through extensive chassis testing and ongoing refinement, this kit is built to deliver sharper handling, everyday comfort, and the durability enthusiasts expect when the miles—and the pace—start adding up. BC avoids the trap of flashy, overly stiff spring specs and instead selects rates that preserve compliance while significantly improving body control. Matched damper valving ties the package together, producing a ride that feels planted, predictable, and easy to live with day after day. The mono-tube design resists heat fade during aggressive use, and the linear piston profile ensures smooth, consistent feedback as cornering loads increase. Because ride height is adjusted independently from preload, you can dial in the stance you want without compromising travel or upsetting the car’s balance. With 30 clicks of simultaneous compression and rebound adjustment, the BR Series covers a wide spectrum of driving styles—from daily commuting to serious weekend work. Key Features Highly customizable configuration 10KG front / 5KG rear spring rates Mono-tube shock construction Linear piston and damping characteristics Independent ride height adjustment 30-position compression and rebound tuning Front camber plates standard on applicable kits Rear camber solutions for select vehicles Custom spring rates and Swift compatibility Optional custom or matched valving Fully rebuildable design Protected by a 2-year manufacturer 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!

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.

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 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 rear damping adjuster on coilovers is usually hidden under a bunch of hard to reach interior panels requiring you to remove carpet, panels and sometimes even the rear seat back in order to adjust the dampening on your BC rear coilovers. The BC Racing rear extender adjuster allow you to make these adjustments without removing the rear interior. Simple make two small holes in the interior above the adjuster and the extension can be passed through the interior panels. Now the adjustments can be performed from above.

BC Racing's new proprietary digressive piston design offers increased damping force at low piston velocities while maintaining a linear damper feel at higher piston velocities. One of the greatest advantages of increased low-speed damping force relates to what the driver feels, e.g., roll, pitch, dive, and quick weight transitions on technical road courses. For The Ultimate In Driver Feel - Choose BC Racing DS Series Coilovers.

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.

For the E90/E92 enthusiast looking to bridge the gap between a high-end street car and a professional race machine, the BC Racing ZX Series offers an unparalleled level of feedback. By moving the compression valving to external canisters, the system effectively manages the heat generated during aggressive driving, maintaining valving accuracy and preventing "damper fade." 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 track curbing while keeping low-speed compression firm for sharp turn-in response. Combined with standard front pillowball camber plates, this system eliminates factory rubber "mush," providing direct, unmediated steering feedback and allowing for aggressive alignment specs. Key Features: Triple-Valved Control: Precision adjustment of 30 clicks Rebound, 20 clicks Low-Speed Compression, and 12 clicks High-Speed Compression. Thermal Management: External canisters keep fluid away from hot brake components to ensure consistent lap times and drift consistency. Dual Piston Design: Combines the best characteristics of the DS and ER series for a broad range of damping authority. Motorsport-Grade Components: TIG-welded heavy-gauge steel shock bodies with black chrome finish and 6061-T6 aluminum components. Serviceable Construction: All components are individual and fully replaceable, ensuring the long-term serviceability of the system. Specifications: Vehicle Fitment: 2006–2011 BMW 3 Series E90 (Sedan) / E92 (Coupe) - Non-M Models. Spring Rates (Default): Front: 5.5 kg/mm | Rear: 9 kg/mm. Spring Type: High-strength SAE9254 cold-wound steel (Swift Spring upgrade available). Adjustability: Independent ride height, spring preload, and 3-way damping. Rebuildable: Fully rebuildable to original manufacturer specifications.
