Product Details

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!

The BR Series is BC Racing's most popular suspension package. Equally at home on street and track the BR Series offers the best of both worlds with ride height and damping adjustability. Damping is adjusted simultaneously and height is adjusted independently of piston and spring stroke. The BR Series offers a minimum 2 inch drop as well as 30 levels of damping adjustment. Assembled by hand in BC Racing's facility, each application undergoes stringent quality control protocols to deliver the best possible suspension product to the consumer. 

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.
