Product Details
BC Racing BR Series Coilovers for the 2015-2021 Mercedes-Benz C300 (W205) are BC Racing's entry-level coilover and the most popular kit in their entire lineup. They offer the most accessible entry into adjustable coilover suspension without sacrificing performance, comfort, build quality, or handling. Every kit is tested and refined until it balances ride quality with performance, which is why BC Racing coilovers are among the best-selling adjustable kits in their segment worldwide.
Every BR Series kit is built around a mono-tube damper with simultaneous compression and rebound adjustment at every corner, giving a wide damping range without the complexity of a race-only setup. Ride height is fully adjustable independent of spring preload, so you set the stance and the ride separately. Drivers who want a different recipe can spec Swift Springs, custom spring rates, or custom valving at checkout, and BC will tune the dampers to match.
BC Racing has been manufacturing adjustable coilovers since 2004 and is one of the most popular coilover brands in the automotive tuning industry for a reason: competitive pricing, deep customization, proven reliability, and a fully rebuildable damper design. Every kit ships with a 2-year manufacturer warranty, lifetime access to BC service parts, and in-house tech support from both BC Racing and the Springrates team.
