It comes in 5 series (BR Series, DS Series, RM Series, ER Series, ZX Series), so you can pick the setup that suits how you drive. Every BC kit is a complete, fully rebuildable coilover system with ride height that adjusts independently of spring compression.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDefault spring rates: Standard: front 6 kg\/mm - rear 4 kg\/mm\u003c\/li\u003e\n\u003cli\u003eCustom spring rates available on request\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBR Series - from $1,774\u003c\/h3\u003e\u003cp\u003eThe BR Series is BC Racing's most affordable full coilover system, and it doesn't cut corners on ride comfort, handling, build quality or ride height. BC Racing tests every vehicle and keeps refining the setup until it is properly balanced, and the off-the-shelf spring rates are picked to sit between comfort and performance, so the car isn't left oversprung. Damping is adjustable over 30 clicks, with compression and rebound set together, which is one of the widest adjustment ranges on the market.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHighly customizable\u003c\/li\u003e\n\u003cli\u003eMono-tube shock design\u003c\/li\u003e\n\u003cli\u003eLinear piston and damping curve\u003c\/li\u003e\n\u003cli\u003eRide height adjusts independently of spring compression\u003c\/li\u003e\n\u003cli\u003e30-click damping adjustment (compression and rebound adjusted together)\u003c\/li\u003e\n\u003cli\u003eFront camber plates standard on applicable kits\u003c\/li\u003e\n\u003cli\u003eRear camber plates available on applicable kits\u003c\/li\u003e\n\u003cli\u003eCustom spring rates and Swift springs available\u003c\/li\u003e\n\u003cli\u003eCustom valving, or valving matched to custom spring rates\u003c\/li\u003e\n\u003cli\u003eFully rebuildable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDS Series - from $2,066\u003c\/h3\u003e\u003cp\u003eThe DS Series uses BC Racing's proprietary digressive piston. It gives more damping force at low piston speeds while keeping a linear feel at higher speeds. That extra low-speed control is what the driver feels most: less roll, pitch and dive, and quicker weight transfer on a technical road course. BC Racing pitches it as the choice for the best driver feel.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHighly customizable\u003c\/li\u003e\n\u003cli\u003eMono-tube shock design\u003c\/li\u003e\n\u003cli\u003eDigressive piston and damping curve\u003c\/li\u003e\n\u003cli\u003eSatin chrome finished shock body\u003c\/li\u003e\n\u003cli\u003eRide height adjusts independently of spring compression\u003c\/li\u003e\n\u003cli\u003e30-click damping adjustment (compression and rebound adjusted together)\u003c\/li\u003e\n\u003cli\u003eFront camber plates standard on applicable kits\u003c\/li\u003e\n\u003cli\u003eRear camber plates available on applicable kits\u003c\/li\u003e\n\u003cli\u003eCustom spring rates; Swift spring compatible\u003c\/li\u003e\n\u003cli\u003eCustom valving, or valving matched to custom spring rates\u003c\/li\u003e\n\u003cli\u003eFully rebuildable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eRM Series - from $2,212\u003c\/h3\u003e\u003cp\u003eThe RM Series uses inverted mono-tube dampers front and rear on cars with McPherson strut suspension from the factory. On cars with front struts only, you get an inverted front strut and an upright BR Series damper at the rear. Inverting the strut puts most of its mass up top, on the sprung side of the chassis, which cuts unsprung weight. The RM's much larger inverted piston shaft handles high lateral loads for longer without fatigue. Those loads only really occur on McPherson struts, not on double A-arm cars.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHighly customizable\u003c\/li\u003e\n\u003cli\u003eInverted mono-tube strut design\u003c\/li\u003e\n\u003cli\u003eLinear piston and damping curve\u003c\/li\u003e\n\u003cli\u003eRide height adjusts independently of spring compression\u003c\/li\u003e\n\u003cli\u003e30-click damping adjustment (compression and rebound adjusted together)\u003c\/li\u003e\n\u003cli\u003eFront camber plates standard on applicable kits\u003c\/li\u003e\n\u003cli\u003eRear camber plates available on applicable kits\u003c\/li\u003e\n\u003cli\u003eCustom spring rates; Swift spring compatible\u003c\/li\u003e\n\u003cli\u003eCustom valving, or valving matched to custom spring rates\u003c\/li\u003e\n\u003cli\u003eFully rebuildable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eER Series - from $2,854\u003c\/h3\u003e\u003cp\u003eThe ER Series is the next step up for drivers who want to tune compression and rebound separately.

It has 3-way adjustable damping: 20 clicks of low-speed compression, 12 clicks of high-speed compression and 30 clicks of rebound. Unlike the inverted ZR, the ZX uses an upright damper, so the upper mount can be replaced, and it combines the strengths of the DS and ER Series.
