Every Series, Every Build, One Authorized Source

BC Racing coilovers have earned their reputation through real-world performance through consistent engineering, genuine vehicle-specific testing, and a price point that puts serious performance coilovers within reach of drivers who actually use them. From the entry-level BR Series to the three-way adjustable ZR and ZX flagship, BC Racing coil overs cover more vehicles, more driving styles, and more suspension goals than almost any other brand at this level.

Why BC Racing Sits Where It Does in the Market

Performance coilovers exist on a spectrum. At the top end, brands like Ohlins and KW deliver exceptional quality at $2,500 and above, but with narrower vehicle coverage and fewer customization options at the point of sale. At the budget end, sealed, non-rebuildable units offer height adjustment but little else. BC Racing coilovers occupy the most useful ground between those two points: monotube construction, fully rebuildable hardware, wide vehicle coverage, custom spring rates at no extra cost, and real adjustability at every level of the lineup.

The Full Series Lineup

BC Racing coils span seven series, each engineered for a distinct purpose. The BR Series delivers 30-way simultaneous damping adjustment and carefully chosen spring rates for street and occasional track use, and remains the most popular racing coilover in BC's range. The DS Series adds digressive piston valving for sharper low-speed body control and more precise chassis feedback. The RM Series uses an inverted monotube damper to reduce unsprung weight and handle higher side loads on MacPherson strut applications. The ER Series introduces external reservoirs on all four corners with independent compression and rebound adjustment. The HM Series combines the RM inverted design with that independent adjustment capability. The ZR and ZX Series are BC's flagship racing coilovers, offering three-way adjustability with independent low-speed compression, high-speed compression, and rebound for drivers who need pro-level control.

Every BC Racing coilover across all series shares a common foundation: independent height adjustment from spring preload via BC's patented concave lower locking ring, monotube shock construction, pillowball mounts on applicable fitments, custom spring rates available at no additional cost, Swift Spring upgrades, and full rebuildability with available replacement parts.

FAQs

What are BC Racing coilovers and what makes them different from other brands?

BC Racing coilovers are fully adjustable monotube coilover systems designed for street, track, and motorsport use. What sets them apart is the combination of genuine vehicle-specific testing, wide vehicle coverage, custom spring rates available at no extra cost, rebuildable construction, and a price point that delivers performance coilover capability without requiring a four-figure step up to European brands. Every kit is built around height adjustment independent of spring preload, a minimum of 30-way damping adjustment, and pillowball mounts on applicable fitments.

Which BC Racing coilover series is right for my build?

The BR Series suits daily drivers and enthusiasts who want a capable, well-balanced upgrade with 30-way simultaneous compression and rebound adjustment. The DS Series is better for regular track use, with digressive piston valving for sharper body control. The RM Series adds an inverted monotube design for MacPherson strut applications with higher lateral loads. The ER Series provides independent compression and rebound adjustment via external reservoirs for session-by-session track tuning. The HM combines the RM's inverted design with ER-level independent adjustment. The ZR and ZX Series are three-way adjustable flagship racing coilovers for competitive driving.

Can I customize BC Racing coilovers before they ship?

Yes. All BC Racing coil overs can be ordered with custom spring rates at no additional cost, with damper valving automatically matched to your chosen rates. You can also add Swift Spring upgrades, select the Extreme Low option where available, and choose camber plates on applicable fitments. Standard BR Series kits that are in stock ship the same business day if ordered before 2pm ET. Custom builds across any series typically take 4 to 6 weeks.

Are BC Racing coilovers rebuildable?

Yes. Every BC Racing coilover is fully rebuildable using individual replacement parts. If a shock cartridge leaks, it can be replaced without replacing the entire unit. This makes BC Racing coilovers a long-term suspension investment rather than a consumable. Replacement parts are available and support is provided through BC Racing North America, which also covers all warranty claims.

What warranty do BC Racing coilovers carry?

BC Racing coilovers come with a 2-year warranty against manufacturing defects. This applies across all series and covers standard and custom-built kits. All warranty claims are processed directly through BC Racing North America. The combination of the 2-year warranty and full rebuildability means a properly maintained set of BC Racing coils can serve a build for many years beyond the initial warranty period.

Why buy BC Racing coilovers from Springrates?

Springrates has been an authorized BC Racing retailer since 2005, making us one of the longest-standing and largest authorized sources in the country. We offer a lowest price guarantee, free shipping on orders over $250, and real-time inventory updated throughout the day. Every kit sold through Springrates is 100% authentic. We also carry deep product knowledge across every BC Racing coilover series, and our team is available to help you choose between options, dial in spring rates, or navigate a custom build.

Do BC Racing coilovers work for both street and track use?

Yes, across different series. The BR Series is specifically tuned for street use with the ability to handle occasional track days comfortably. The DS and RM Series handle regular track use while remaining street driveable. The ER, HM, ZR, and ZX Series are increasingly track-focused but can be softened for street driving when needed. No single BC Racing coilover series suits every driver equally, which is why Springrates maintains the full lineup and can guide you to the right series for your specific use case and vehicle.
