Product Details
BC Racing BR Series Coilovers for the 2012-2018 Mercedes-Benz CLS550 (C218) 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 extensively tested on the CLS550 C218 chassis and refined until it balances ride quality with performance, the reason CLS550 coilovers from BC Racing are 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, 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. 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.
Since 2004, BC Racing has grown into one of the most trusted names in aftermarket coilovers, not by racing to the bottom on price, but by pairing that price with real build quality, deep customization options, and a damper design any suspension shop can rebuild instead of replacing. These CLS550 coilovers arrive tuned for the C218 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.
