They 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 developed specifically for the Mercedes-Benz GLC300 and refined to balance ride quality with performance, which is why BC coilovers are the best-selling adjustable kits in their segment worldwide.\u003c\/p\u003e \u003cp\u003eDS 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. The off-the-shelf setup from BC Racing is deliberately balanced, spring rates and valving chosen so the kit feels comfortable day-to-day without giving up performance when you push it. Drivers who want a different recipe can spec Swift Springs, custom spring rates, or fully custom valving at checkout; BC will tune the dampers to match, which is a depth of customization most brands only offer on their top-tier kits.\u003c\/p\u003e \u003cp\u003eBC 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 that lasts years instead of seasons. These BC Racing GLC300 coilovers arrive ready to bolt in, with no break-in period and 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.\u003c\/p\u003e \u003ch3\u003eFeatures\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e30-level simultaneous compression\/rebound damping adjuster\u003c\/li\u003e \u003cli\u003eMono-tube damper with BC's proprietary digressive piston\u003c\/li\u003e \u003cli\u003eSilver satin-chrome finished shock body (visually distinct from the BR Series)\u003c\/li\u003e \u003cli\u003eRide height adjustable independent of spring preload\u003c\/li\u003e \u003cli\u003eUpper mount hardware varies by chassis, camber plates, pillowball, or reused OEM mounts.
