I-121-ZX - BC Racing ZX Series Coilover Suspension Kit - E46 M3 Convertible
BC Racing ZX Series Coilover Suspension Kit - E46 M3 Convertible
For the E46 M3 Convertible enthusiast looking to bridge the gap between a high-end street car and a dedicated race machine, the BC Racing ZX Series offers an unparalleled engineering approach. By moving the compression valving to the external canisters, the system maintains its integrity under high-stress, high-temperature conditions, effectively eliminating "damper fade." For the E46 M3 platform—especially the convertible which requires higher roll stiffness to compensate for chassis flex—the ZX Series' 12kg rear spring rate and advanced damping provide the stability needed to maintain a flat cornering attitude. The system features standard front pillowball camber plates to eliminate factory rubber "mush," providing direct and unmediated steering feedback to the driver.
Key Features:
Enhanced Thermal Management: External canisters keep fluid away from brake heat to maintain valving accuracy lap after lap.
Camber Adjustable Top Mounts: High-quality aluminum alloy plates allow for aggressive track alignments to maximize the tire contact patch.
Pillowball Rear Mounts: Replaces rubber bushings with solid spherical bearings (on applicable kits) 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 Convertible (E46 Chassis).
Spring Rates (Default): Front: 8 kg/mm | Rear: 12 kg/mm (Swift Springs standard).
Piston Design: Linear Twin-Piston with remote canister valving.
Adjustment Range: 3-Way Independent (Rebound / Low-Speed Compression / High-Speed Compression).
Warranty: 1-Year limited manufacturer's warranty.
