Product Details
BC Racing BR Series Coilovers for the 1969-1974 BMW 2500 3.0 CS/New Six (E9) 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 2500 3.0 CS/New Six E9 chassis and refined until it balances ride quality with performance — the reason 2500 3.0 CS/New Six 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.
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 2500 3.0 CS/New Six coilovers arrive tuned for the E9 chassis and ready to install — note that this is a weld-in kit and requires professional fabrication. 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.
