BR Series

"Product images shown are for reference only and may not accurately represent the actual product received"

The BC Racing BR Series offers the most affordable entry into coilover suspension without sacrificing performance, comfort, build quality, vehicle height, or handling. This is done by extensively testing each vehicle then refining the coilover characteristics as many times as needed to ensure the most well-balanced and affordable aftermarket suspension conceivable. BC Racing takes great pride in choosing spring rates for our off-the-shelf kits that strike the perfect balance between comfort and performance so you're never stuck with an oversprung suspension like many other brands sell. BC Racing offers one of the widest ranges of damping adjustment with 30-clicks of compression/rebound adjusted simultaneously on the BR Series. With meticulously chosen spring rates, damper valving, and one of the widest adjustment ranges in the industry, you can't go wrong with the BC Racing BR Series Coilover System.

DS Series

"Product images shown are for reference only and may not accurately represent the actual product received"

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.

ER Series

"Product images shown are for reference only and may not accurately represent the actual product received"

The BC Racing ER Series Coilover System is the next evolution in your suspension tuning and vehicle setup needs. The ER Series offers 30-clicks of independently adjustable compression and rebound with remote reservoirs to increase oil capacity and help with faster heat dissipation. Each ER Series Coilover System undergoes the same rigorous testing and development as the coilover series that precede it, with the addition of more extensive real-world track testing. For racers and enthusiasts that are looking for more adjustability in terms of varying compression and rebound settings, look no further than the BC Racing ER Series Coilover System.

HM Series

"Product images shown are for reference only and may not accurately represent the actual product received"

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!

RM Series

"Product images shown are for reference only and may not accurately represent the actual product received"

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.

ZR Series

"Product images shown are for reference only and may not accurately represent the actual product received"

The BC Racing ZR Series Coilovers offer the most adjustability of any BC Racing Coilover System to date. Each ZR Series Coilover System is track tested and developed specifically for racers looking for more damping adjustability than the ER or HM Series can provide. The ZR Series offers 15-clicks of low-speed compression adjustment, 12-clicks of high-speed compression adjustment, and 30-clicks of rebound adjustment. They also offer full height adjustability independent of piston shaft travel and spring compression. On cars with McPherson struts, the ZR Series comes standard with an inverted mono-tube damper. The damper has a steel braided line exiting the top of the damper leading to the external reservoirs that can be remotely mounted on the chassis for easy adjustment. Cars with Double A-Arm suspension come with upright dampers. These dampers have steel braided lines or solid stems that exit the damper at the bottom and lead to the external reservoir that can be mounted under the chassis or on the shock body itself.

*Not all vehicles allow for inverted front and rear dampers. In such cases an upright mono-tube damper will be supplied. The braided line/hard stem for the external reservoir exits the base of the damper when not inverted. Please note that not all vehicles use camber plates in the front and/or rear. In such cases pillowball top mounts are supplied in place of camber plates on HM & ZR Series Coilover Systems.

ZX Series

The BC Racing ZX Series Coilovers are the highest level of adjustability within the BC Racing coilover system to date, next to the ZR series. Designed specifically for racing and track use, the ZX Series features 3-way adjustable damping force. The ZX Series provides 20 clicks of low-speed compression, 12 clicks of high-speed compression, and 30 clicks of rebound adjustment. The ZX Series adopts an upright cylinder design, rather than inverted cylinders used on the ZR series. This allows for the possibility of replacing the upper mount, while combining the excellent characteristics of the DS and ER series. Coupled with ultra-high viscosity index racing shock fluid, the ZX Series can maintain outstanding performance on the track and in drifting competitions for extended periods.��
