BC Racing ZX Series Coilovers for 2004-2013 Mazda 3 FWD (BK/BL)

BC Racing ZX Series Coilovers for the 2004-2013 Mazda 3 (BK3P) 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 BK3P chassis and refined until it balances ride quality with performance, the reason 3 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, 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”s reputation in the aftermarket suspension world is built on four things: competitive pricing that beats the rest of the fully-adjustable market, ization 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 coilovers arrive tuned for the BK3P 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.
