BC Racing has made a name for themselves in the automotive enthusiast communities by developing adjustable, street-and-track capable coilover kits for over a decade that are not only extremely effective, but also don't brake the bank!

One of BC Racing's most advanced models yet is the BC Racing ER Series coilover. The ER features large external front and rear reservoirs, separate rebound and compression adjustment, and a twin piston design for maximum performance and tuning. The external reservoirs displace a higher capacity of oil allowing for cooler operating temperatures over an extended period of time. The external reservoirs also house the secondary piston which allows for the adjustment of compression. This is the perfect coilover system for the person who wants to fine-tune their setup using the separate, 30-level, rebound and compression tuning knobs. The ER Series damping (compression and rebound) can be adjusted with your fingers, meaning there is no need to carry additional tools to dial in your setup at the track.

All springs used, linear, S-barrel, and v-barrel, are made of SAE9254 steel and utilize a Zinc coating under a powder coating finish to ensure rust cannot penetrate the metal of the spring and compromise performance or reliability. Liner springs are used in in places possible unless otherwise limited by the OE design of the vehicle which does not allow it. In that case, S-Barrel or V-Barrel springs are used to match OE shape/style specifications and the spring's rate is then matched to the linear rate.

BC Racing creates their kits utilizing a wide variety of shock types, lengths and diameters. Each vehicle depending on their data from R&D, and accounting for the OEM suspension design will utilize a different style of shock. Each shock is hand assembled in their factory and dyno tested before use in their kits. Shocks are paired together by their compression and rebound numbers after dyno testing for even and precise quality and performance. Each shock body used in their system is 53mm for added strength, performance, and increased fluid capacity (unless limited spacing will not allow). The shocks are then coated in black chrome for a clean, cohesive appearance and corrosion resistance.
