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 DS Series Coilovers use a proprietary digressive piston design that offers the driver increased damping force at low speed piston velocities, which is what the driver actually feels when attacking their favorite track or twisty mountain road. For many decades in the racing industry its been the standard for drivers and engineers to examine low speed piston velocities (0mm/s to 50mm/s) and interrupt those figures as driver feel (they are also analogous to movement of the sprung mass of a vehicle, i.e., the body). Low speed piston velocities refer to the speed at which the damper piston is compressing and rebounding from 0mm/s to 50mm/s on a Force vs. Velocity Curve (more commonly known as a shock dyno graph).
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.
