BC Racing is proud to provide coilovers that strike the best balance between performance and cost. We have designed all the most popular and essential features into our coilovers while keeping the end price down for the consumer. Whether you are cruising down the street, enjoying your favorite twisty mountain road or tearing up a race track we have a coilover system for you. You get to choose your springs rates, either keeping the recommended spring rates or selecting from our available stock. We even install the springs for you so you don't have the hassle of doing it in your garage or living room. As an added service if you choose spring rates 4k higher or lower than the recommended setting we will revalve the dampers for you. Here at BC Racing we beleive you shouldn't have to pay a premium price for a quality coilover system.
BR Coilovers w. free rear extender adjusters
Our BR model is perfect for street driving and occasional road course duty. With easily accessible adjustment knobs for fine tuning your compression/rebound and separately adjustable ride height, having a performance coilover system couldn’t be any easier. You choose how low or high you want your vehicle, no preset ride height here, and our patented concave lower locking ring keeps it locked in. All of our systems come with pillowball mounts to provide the most feedback possible from your suspension and to sharpen your steering response. BC’s available front and rear camber plates also allow you to get the perfect alignment setup without compromise. All this while providing a strong, attractive looking coilover system.

RAM Inverted Coilovers
BC Racings inverted RAM model includes all of the great BR features and then takes it a notch higher. By using an inverted coilover system we move the vital damper fluid away from the detrimental heat sources to avoid overheating the fluid and causing damper fatigue under extreme conditions. The inverted setup also handles high-g loads better and is much more durable under stress situations, such as a race track. Another advantage is reducing unsprung weight by moving the heavy parts to the chassis mounting points. This is a great coilover for those looking to attack a race track, hill climb or tarmac rally.

ER Coilovers w. external reservoirs
Our newest and most advanced model yet is the ER series coilover. It features large external reservoirs front and rear, separate rebound and compression adjustment and a twin piston design. The external reservoirs hold much more oil than the conventional coilover, allowing the coilover to operate for a much longer period of time before overheating. The external reservoirs also house the secondary piston, which allows for the fine tuning of compression. This is the perfect coilover system for the person who wants to fine tune there setup using the separate, 30-way, rebound and compression tuning dials.
