Product Details
BC Racing ZR Series Coilovers for the 1992-1999 BMW 3-Series E36 True Rear Coilover deliver the deepest damping adjustability in BC Racing's lineup, with Swift Springs included standard and three axes of independent tuning for competitive track programs. Every kit is extensively tested on the 3-Series E36 True Rear Coilover chassis and refined until it balances ride quality with performance — the reason 3-Series E36 True Rear Coilover coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.
ZR Series kits use an inverted mono-tube damper with a linear twin-piston design, feeding three independent adjustment circuits. Swift Springs come standard — not as an upgrade — and the kit is race-tuned out of the box. 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 3-Series E36 True Rear Coilover coilovers arrive tuned for the 3-Series E36 True Rear Coilover 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.
