BC Racing ZX Series Coilovers (True Rear) for 2015-2018 BMW M3 RWD (F80)

BC Racing ZX Series Coilovers for the 2015-2018 BMW F82 M3 & M4 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 F82 M3 & M4 chassis and refined until it balances ride quality with performance, the reason F82 M3 & M4 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. Where BC Racing separates itself is tuning philosophy: every off-the-shelf spring rate and damper setup is chosen to stay comfortable on daily roads while still delivering real performance at the track. If you want something different, Swift Springs, rates, and valving are all options at checkout, BC will match the valving of the dampers to whatever springs you pick, something most brands don”t offer outside their flagship race lineup.

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 ization, proven reliability, and a fully rebuildable damper design that lasts years instead of seasons. These F82 M3 & M4 coilovers arrive tuned for the F82 M3 & M4 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.
