BC Racing DS Series Coilover Suspension Kit - G30 AWD

For the BMW G30 owner looking to eliminate the "wallow" of factory suspension, the BC Racing DS Series offers a professional-grade motorsport approach. Built from TIG-welded 304 stainless steel and heavy-duty aluminum, this system is designed to withstand the rigors of high-intensity driving. The DS Series includes high-strength SAE9254 cold-wound steel springs, which have been tested through over 500,000 cycles with less than 5% deformation. By moving the secondary damping piston to the digressive valving architecture, the system provides a sharper turn-in and more direct steering feedback. Every DS Series kit is hand-assembled and fully rebuildable, ensuring it remains a long-term performance investment for your BMW. Key Features: Enhanced Chassis Poise: Digressive damping curve specifically combats the weight of the G30 chassis during spirited driving. Pillowball Top Mounts: High-quality aluminum alloy mounts provide direct feedback and eliminate factory rubber compliance. 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. Customization Ready: Fully compatible with custom spring rates and Swift Spring upgrades for tailored track setups. Specifications: Vehicle Fitment: 2017–2023 BMW 5-Series (G30) Sedan AWD / xDrive. Spring Rates (Default): Front: 9 kg/mm | Rear: 4.2 kg/mm. Adjustability: Independent ride height, independent spring preload, and 30-way damping. Maintenance: Fully rebuildable with all replacement parts readily available. Warranty: 1-Year limited manufacturer's warranty.
