BC Racing ZR/ZX Series Coilovers for the 2001-2006 Bmw 3 Series M3 Sedan/Coupe RWD User-Replaceable Camber Plate, On- or Off-Center (E46 M3) represent the absolute pinnacle of BC Racing's coilover lineup — a 3-way independently adjustable system with separate low-speed compression, high-speed compression, and rebound adjustment at every corner.
