BC Racing BR Series
Adjustable coilover suspension for street, track, and stance builds. BR · DS · RM · ER · HM · ZR · ZX series available with custom spring rates, Swift spring upgrades, and a 1-year warranty. Free shipping on every order.
PMD Driven is your authorized source for the full BC Racing coilover lineup. Every kit is engineered, dyno-tested, and tuned for a specific vehicle application — no generic "fits all" hardware. Whether you're lowering a daily driver, tightening up a weekend autocross car, or building a wheel-to-wheel race chassis, there's a BC Racing series matched to the job.
The BR Series is the platform's most popular coilover and the entry point for the catalog at $1,195. It's a linear mono-tube design with 30 clicks of damping, ride-height adjustment independent of spring compression, and front camber plates included on every applicable kit. The DS Series steps up to a digressive piston for sharper low-speed feel — preferred for spirited street and autocross use. RM uses an inverted strut for McPherson platforms. ER, HM, ZR, and ZX add external reservoirs, twin-piston damping, Swift springs, and 3-way independent adjustment for serious track and race use.
Every BC Racing coilover system is fully rebuildable, backed by a 1-year manufacturer warranty, and ships free in the U.S. Custom spring rates, custom valving, and Swift spring upgrades are available on most applications. Use the Year/Make/Model picker above to confirm fitment, or filter by series chip.
