Product Details

BC Racing DS Series Coilovers for the 2015-2021 Mercedes-Benz C300 Sedan (W205) blend street-tuned ride quality with track-ready adjustability, giving you more body control than any OEM damper without the harshness of a pure race kit. Every kit is extensively tested on the C300 Sedan W205 chassis and refined until it balances ride quality with performance, the reason C300 Sedan coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.

DS Series kits pair a mono-tube damper with BC's proprietary digressive piston design, increased low-speed damping for flat corner entry, compliant high-speed response over expansion joints and potholes. The finished shock body is silver, visually distinct from the BR Series, and ride height is adjustable independent of spring preload. Where BC Racing separates itself is tuning philosophy: every off-the-shelf spring rate and damper setup is chosen to stay comfortable on daily roads while still delivering real performance at the track. If you want something different, Swift Springs, custom rates, and custom valving are all options at checkout, BC will match the valving of the dampers to whatever springs you pick, something most brands don't offer outside their flagship race lineup.

BC Racing's reputation in the aftermarket suspension world is built on four things: competitive pricing that beats the rest of the fully-adjustable market, customization depth that rivals the top-tier race brands, long-term reliability earned over 20 years of production, and a rebuildable design that keeps the same set of dampers serving you through multiple builds. These C300 Sedan coilovers arrive tuned for the W205 chassis and ready to bolt in, no break-in period, no guessing at setup. Every kit ships with a 2-year manufacturer warranty, lifetime access to BC service parts (pistons, seals, shafts, no unit replacement required when it's time for a rebuild), and in-house tech support from both BC Racing and the Springrates team.
