BC Racing ER 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.

BC Racing Coilovers FAQ
BC Racing manufactures over 1,800 vehicle-specific coilover applications across nearly every popular performance and luxury platform — Honda, Toyota, Subaru, BMW, Audi, Mercedes-Benz, Ford, Mazda, Nissan, Infiniti, Lexus, and more. Use the Year/Make/Model picker at the top of this page, or browse the full BC Racing catalog to confirm your fitment. If you don't see your application, contact us — BC Racing offers custom-built kits for nearly any vehicle.
The BR Series is BC Racing's entry-level mono-tube coilover with linear damping. The DS Series uses a digressive piston for sharper low-speed response. RM is an inverted-strut design for McPherson platforms. ER adds external reservoirs with separate compression and rebound adjustment. HM combines inverted strut + external reservoir + Swift springs. ZR is 3-way adjustable (15 low-speed, 12 high-speed, 30 rebound). ZX matches the ZR's adjustability and adds user-replaceable camber plates. See the comparison table above for a side-by-side.
Yes. Every BC Racing coilover system features ride-height adjustment that's independent of spring compression, plus damping adjustment via a clicker dial on top of each strut. The BR, DS, RM, ER, HM series offer 30 clicks of combined or independent compression/rebound. The ZR and ZX series step up to true 3-way adjustability with separate low-speed compression, high-speed compression, and rebound circuits. All applicable kits include front camber plates standard.
Standard, in-stock BC Racing kits ship from our warehouse within 1–2 business days with free U.S. shipping. Made-to-order configurations — custom spring rates, custom valving, Swift spring upgrades, ER/HM/ZR/ZX series — typically build in 2–4 weeks. Tracking is sent the moment your kit leaves the warehouse. International orders are calculated at checkout.
Front camber plates are standard on every applicable BC Racing kit. Rear camber plates are an available add-on on most BR and DS Series applications, and standard on ER, HM, ZR, and ZX Series kits where the chassis allows. On vehicles where camber plates aren't applicable, BC Racing supplies pillowball top mounts instead.
All BC Racing coilovers are designed and tested for performance use. The BR and DS Series are well-suited to autocross, weekend HPDE, and aggressive street driving. For dedicated track or wheel-to-wheel race use, the ER, HM, ZR, and ZX Series add external reservoirs, twin-piston damping, Swift springs, and 3-way adjustability for fine-tuning at the track. Custom spring rates and custom valving are available on request.
Yes. Every BC Racing coilover system is fully rebuildable. Service kits, replacement seals, and damper rebuilds are available through PMD Driven as an authorized BC Racing dealer, so you don't need to buy a new set when service is due. Typical interval is 25,000–40,000 miles for street use, sooner for heavy track use.
BC Racing covers every coilover system with a 1-year warranty against manufacturer defects. Warranty claims are handled directly through PMD Driven — contact us with your order number, and we'll coordinate inspection, replacement, or repair with BC Racing on your behalf.
