BC Racing DS Series Coilover Suspension Kit - E46 Convertible

The BC Racing DS Series for the E46 Convertible is built using motorsport-grade materials designed to withstand the rigors of spirited driving and technical road courses. Because the E46 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 fully rebuildable and customizable, 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 chassis to its limits. Key Features: Front Camber Plates: Precision-engineered aluminum plates for surgical alignment and increased turn-in bite. Satin Chrome Finished Shock Body: A highly durable coating that resists the elements while providing a high-end look. Linear Spring Piston: While the valving is digressive, the springs remain linear to provide a predictable and consistent feel. Fully Rebuildable: Every part, from the seals to the valving, is serviceable and replaceable. Custom Spring Rate Compatibility: Can be ordered with custom valving paired specifically to your requested spring rates. Specifications: Vehicle Fitment: 2000–2006 BMW 3-Series (E46) Convertible (All models except M3). Spring Rates (Default): Front: 6 kg/mm | Rear: 8 kg/mm. Optional Rates: Custom rates available (e.g., 8kg/10kg) for more track-oriented setups. Piston Diameter: 46mm. Adjustability: Ride height, spring preload, and 30-way damping.
