Product Details
BC Racing ZX Series Coilovers for the 1990-2005 Mazda MX-5 Miata (NA/NB) 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 MX-5 Miata chassis and refined until it balances ride quality with performance, the reason MX-5 Miata 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 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 customization, proven reliability, and a fully rebuildable damper design that lasts years instead of seasons. These MX-5 Miata coilovers arrive tuned for the MX-5 Miata 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.
