Product Details

BC Racing BR Series Coilovers for the 2003-2007 Cadillac CTS 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 CTS chassis and refined until it balances ride quality with performance, the reason CTS 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. 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 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 CTS coilovers arrive tuned for the CTS 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.
