The BC Racing V1 Series provides an accessible entry into coilover suspension without compromising on performance, comfort, build quality, ride height adjustment, or handling. Each application is developed through extensive vehicle testing, with the suspension characteristics carefully refined to achieve the best possible balance between performance and affordability. BC Racing places particular emphasis on spring rate selection, ensuring off-the-shelf kits deliver a well-judged balance of comfort and control—avoiding the overly stiff setups commonly found in many aftermarket systems.

BC Racing’s latest proprietary digressive piston design delivers increased damping force at low piston velocities (0–50 mm/s) while preserving a smooth, linear damping response at higher speeds. This enhanced low-speed control significantly improves what the driver feels through the chassis, reducing body roll, pitch, and dive while providing sharper response during rapid weight transfer—especially on technical road courses.

The BC Racing inverted RM Series builds on the proven features of the BR Series and elevates performance to the next level. By utilising an inverted coilover design, critical damper fluid is positioned away from major heat sources, reducing the risk of overheating and damper fade during extreme use. This inverted configuration also improves strength under high G-loads and offers superior durability in prolonged high-stress environments such as circuit driving. Additionally, relocating heavier components closer to the chassis helps reduce unsprung weight, enhancing suspension response and stability. The RM Series is an ideal choice for demanding applications including track days, hill climbs, and tarmac rally use.

The BC Racing ER Series Coilover System represents the next step in advanced suspension tuning and vehicle setup. Featuring 30-click independently adjustable compression and rebound, along with remote reservoirs to increase oil capacity and improve heat dissipation, the ER Series is built for demanding performance use. Like all BC Racing coilover systems, each ER kit is rigorously developed and tested, with additional real-world track validation to ensure consistent performance under extreme conditions. Designed for drivers who require a higher level of adjustability and control, the ER Series delivers precise damping control for serious track and competition-focused applications.

The BC Racing HM Series Coilover System combines the key strengths of both the RM and ER Series to deliver a high-performance suspension solution for serious track use. It features an inverted monotube damper design, as found in the RM Series, paired with the independently adjustable compression and rebound control of the ER Series. On MacPherson strut applications, the HM Series utilises inverted monotube dampers at both the front and rear, with steel-braided lines connecting the dampers to external reservoirs. These reservoirs increase oil capacity for improved thermal stability and heat dissipation, while also housing the secondary damping piston for enhanced control under extreme conditions.

The BC Racing ZR Series Coilovers deliver the highest level of adjustability in the BC Racing range, developed and track-tested specifically for drivers who demand greater damping control than the ER or HM Series can offer. The ZR Series features an advanced adjustment range, including 20-click low-speed compression, 12-click high-speed compression, and 30-click rebound adjustment, along with fully independent ride height adjustment that does not affect damper stroke or spring preload.

On vehicles equipped with MacPherson strut suspension, the ZR Series is supplied with inverted monotube dampers, featuring steel-braided lines exiting the top of the damper and connecting to remotely mountable external reservoirs for convenient access. Vehicles with double A-arm suspension use upright dampers, with steel-braided lines or solid stems exiting the bottom of the damper and feeding external reservoirs that can be mounted either on the chassis or directly on the shock body. Designed for competitive motorsport use, the ZR Series offers uncompromising tuning flexibility and performance under extreme track conditions.

The BC Racing ZX Series represents the most advanced and adjustable coilover system in the BC Racing lineup to date. Developed specifically for competitive track and racing applications, the ZX Series features true 3-way damping adjustment, offering 20-click low-speed compression, 12-click high-speed compression, and 30-click rebound control. Built around an upright damper design, the ZX Series allows for upper mount replacement while combining key performance characteristics from the DS and ER series. Paired with ultra-high viscosity index racing shock fluid, the ZX Series delivers consistent, fade-resistant performance, making it ideal for prolonged track sessions and high-demand drifting environments.
