I-121-DS - BC Racing DS Series Coilover Suspension Kit - E46 M3 Convertible
BC Racing DS Series Coilover Suspension Kit - E46 M3 Convertible
The BC Racing DS Series for the E46 M3 Convertible is built using motorsport-grade materials designed to withstand the rigors of spirited driving and technical road courses. Because the E46 M3 platform benefits greatly from increased front camber, this kit comes standard with front pillowball camber plates. These plates replace the compliant factory rubber mounts, providing unmediated feedback to the driver and allowing for aggressive alignment settings to maximize tire contact patches. Every DS Series kit is hand-assembled and fully rebuildable, with the option to upgrade to Swift Springs for even more consistent spring rates and reduced weight. Whether you're carving canyons or attending a weekend track day, the DS Series provides the stability and feedback needed to push the E46 M3 chassis to its limits.
Key Features:
Front Camber Plates: Precision-engineered aluminum alloy plates for surgical alignment and increased turn-in bite.
Patented Locking Ring: Features a concave lower locking ring that prevents the system from vibrating loose even under track conditions.
Bearing-Mounted Spring Platforms: Minimizes "spring binding" or popping during low-speed steering maneuvers.
Fully Rebuildable: Every component, from the seals to the valving, is individual and replaceable for long-term serviceability.
Customization Ready: Fully compatible with custom spring rates and Swift Spring upgrades for tailored track setups.
Specifications:
Vehicle Fitment: 2000–2006 BMW M3 Convertible (E46 Chassis).
Spring Rates (Default): Front: 7 kg/mm | Rear: 12 kg/mm.
Spring Type: High-strength SAE9254 cold-wound steel.
Adjustability: Independent ride height, independent spring preload, and 30-way damping.
Warranty: 2-Year limited manufacturer's warranty.
