BC Racing DS Series Coilovers for the 2017-2024 Audi A4 (B9) 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 A4 w/EDC B9 chassis and refined until it balances ride quality with performance, the reason A4 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. 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, spring rates, or fully valving at checkout; BC will tune the dampers to match, which is a depth of ization most brands only offer on their top-tier kits.
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 ization, proven reliability, and a fully rebuildable damper design that lasts years instead of seasons. These A4 coilovers arrive tuned for the B9 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.
