I-121-ZR - BC Racing ZR Series Coilover Suspension Kit - E46 M3 Convertible
BC Racing ZR Series Coilover Suspension Kit - E46 M3 Convertible
For the professional-level racer or the extreme enthusiast, the BC Racing ZR Series addresses the unique geometric and thermal requirements of the E46 M3 platform. By utilizing inverted front struts with a massive 42mm piston shaft, the ZR Series provides extreme structural rigidity, preventing geometry deflection under heavy braking and cornering loads. The 3-way adjustment allows the driver to "dial in" the car for specific obstacles; for instance, softening high-speed compression to soak up aggressive curbing while keeping low-speed compression firm for immediate turn-in response. Combined with standard pillowball top mounts, this system eliminates the "mushy" feel of factory rubber, providing direct, unmediated feedback to the driver.
Key Features:
Reduced Damper Fade: Remote external canisters move fluid away from hot brake components to ensure consistent lap times.
Camber Adjustable Top Mounts: High-quality aluminum plates allow for aggressive track alignments to maximize the tire contact patch.
Pillowball Rear Mounts: Replaces rubber bushings with solid spherical bearings for increased response and precision.
Patented Concave Locking Ring: BC Racing’s unique design ensures lower mounts remain securely locked, even under extreme track vibration.
Fully Rebuildable: Every component is individual and replaceable, making this a long-term investment in the car's competitive potential
Specifications:
Vehicle Fitment: 2000–2006 BMW M3 (E46) Convertible / Coupe.
Spring Rates (Default): Front: 8 kg/mm | Rear: 12 kg/mm.
Construction: TIG-welded steel and CNC-machined aluminum.
Adjustment Range: 3-Way Independent (Rebound / Low-Speed Compression / High-Speed Compression).
Warranty: 1-Year manufacturer’s warranty against defects.
