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.

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!

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.

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

For the F31 Touring owner looking to dominate the track while maintaining a refined street presence, the BC Racing ER Series offers a "motorsport-first" engineering approach. The inverted-style front struts (on applicable MacPherson designs) and external canisters move the weight of the fluid away from the hubs, reducing unsprung weight and improving the suspension's ability to react to high-speed road imperfections. The system includes bearing-mounted upper spring platforms to eliminate spring "binding" or popping during tight maneuvers. With its massive range of adjustability and robust build quality, the ER Series transforms the F31 wagon into a highly capable, predictable, and remarkably fast track machine. Key Features: Reduced Unsprung Weight: Strategic component placement allows the wheels to track road surfaces more effectively for increased grip. Advanced Damping Control: 30 clicks of compression (on the reservoir) and 30 clicks of rebound (on the shock top) for 900 possible damping combinations. Pillowball Top Mounts: Eliminates the "mushy" feel of factory rubber bushings, providing direct and unmediated feedback to the driver. Concave Lower Locking Ring: BC Racing's patented design prevents the lower mounts from vibrating loose even under extreme track vibration. Serviceable Design: All components are individual and fully replaceable, making the system a long-term investment for the life of the vehicle. Specifications: Vehicle Fitment: 2012–2019 BMW 3-Series (F31) Touring / Wagon (Models with 3-Bolt Top Mounts). Spring Rates (Default): Front: 6 kg/mm | Rear: 10 kg/mm. Spring Type: High-strength SAE9254 cold-wound steel springs. Adjustability: Independent ride height, independent spring preload, and independent 2-way damping. Warranty: 2-Year limited manufacturer's warranty against defects.

    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.

    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!

    If you’re stepping into coilovers for the first time and refuse to trade comfort for capability, the BC Racing BR Series is one of the most well-rounded systems you can bolt on. Extensive chassis-specific R&D and real-world validation mean the setup arrives ready to perform — comfortable enough for daily duty, composed when the pace increases. BC selects spring rates to maintain ride quality while still delivering the body control enthusiasts expect. Combine that with matched damper valving and a wide adjustment range, and you get a package that adapts easily to street driving, back road runs, or time spent at the circuit. A mono-tube damper layout helps maintain consistency as temperatures rise, and the linear piston profile keeps feedback predictable near the limit. Because ride height is adjusted separately from preload, you can fine-tune stance without reducing usable suspension travel. Thirty clicks of combined compression and rebound adjustment give you meaningful flexibility — compliant for commuting, disciplined for competition.

    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 aluminium components (top mounts, locking collars etc) are anodised 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.
