I-114-ER - BC Racing ER Series Coilover Suspension Kit - F31 (3-Bolt Top Mounts)
BC Racing ER Series Coilover Suspension Kit - F31 (3-Bolt Top Mounts)
For the F31 Touring owner looking to dominate the track while maintaining a refined street presence, the BC Racing ER Series offers a "motorsport-first" engineering approach. The inverted-style front struts (on applicable MacPherson designs) and external canisters move the weight of the fluid away from the hubs, reducing unsprung weight and improving the suspension's ability to react to high-speed road imperfections. The system includes bearing-mounted upper spring platforms to eliminate spring "binding" or popping during tight maneuvers. With its massive range of adjustability and robust build quality, the ER Series transforms the F31 wagon into a highly capable, predictable, and remarkably fast track machine.
Key Features:
Reduced Unsprung Weight: Strategic component placement allows the wheels to track road surfaces more effectively for increased grip.
Advanced Damping Control: 30 clicks of compression (on the reservoir) and 30 clicks of rebound (on the shock top) for 900 possible damping combinations.
Pillowball Top Mounts: Eliminates the "mushy" feel of factory rubber bushings, providing direct and unmediated feedback to the driver.
Concave Lower Locking Ring: BC Racing's patented design prevents the lower mounts from vibrating loose even under extreme track vibration.
Serviceable Design: All components are individual and fully replaceable, making the system a long-term investment for the life of the vehicle.
Specifications:
Vehicle Fitment: 2012–2019 BMW 3-Series (F31) Touring / Wagon (Models with 3-Bolt Top Mounts).
Spring Rates (Default): Front: 6 kg/mm | Rear: 10 kg/mm.
Spring Type: High-strength SAE9254 cold-wound steel springs.
Adjustability: Independent ride height, independent spring preload, and independent 2-way damping.
Warranty: 2-Year limited manufacturer's warranty against defects.
