Product Details

BC Racing ZX Series Coilovers for the 2012-2018 BMW 3-Series F30 bring the same three-axis adjustability as the race-spec ZR Series with valving tuned for drivers who split time between street and track. Every kit is extensively tested on the 3-Series F30 chassis and refined until it balances ride quality with performance — the reason 3-Series F30 coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.

ZX Series kits share the three-axis damper architecture of the race-spec ZR Series, tuned out of the box for drivers who want race-grade adjustability without the ride harshness on the commute home. 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 F30 coilovers arrive tuned for the 3-Series F30 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.
