BC Racing DS Series Coilover Suspension Kit - F31 (3-Bolt Top Mounts) I-114-DS

DS Series Coilover Suspension Kit - F31 (3-Bolt Top Mounts)

For the F31 Touring enthusiast who demands superior feedback and body control, the BC Racing DS Series utilizes a proprietary digressive piston design. This architecture provides increased damping force at low piston velocities—perfect for controlling body roll, dive, and squat during quick weight transitions—while transitioning to a linear curve at higher speeds to maintain compliance over bumps. Finished in a premium satin chrome, the DS Series is built for those who prioritize handling precision on technical roads and autocross courses. Like the BR series, it maintains full adjustability but offers a more sophisticated damping profile for the "Ultimate Driver Feel." Key Features: Digressive Piston Design: Enhanced low-speed damping to eliminate "wallow" and improve steering response and turn-in. Satin Chrome Finish: Premium aesthetic and improved corrosion resistance for the shock bodies. 30-Click Adjustment: Unified compression and rebound adjustment for simple, effective trackside tuning. Fixed Spring Seat: Ride height is adjusted via the bottom mount to preserve full stroke and prevent "bottoming out." Camber Plates Included: High-quality front pillow-ball camber plates for aggressive alignment specs. Specifications: Vehicle Fitment: 2012–2019 BMW 3-Series (F31) Touring Wagon (Models with 3-bolt front top mounts). Spring Rates (Default): Front: 6 kg/mm | Rear: 10 kg/mm. Optional Rates: Available with custom Front (up to 18kg) and Rear (up to 18kg) standard or Swift springs. Design: Mono-tube shock with digressive damping curve. Warranty: 2-Year limited manufacturer's warranty.
