The BC Racing BR Series coilover kit for the BMW 3 Series E46 (1998–2006, excluding M3) is designed to deliver a perfectly balanced suspension upgrade for drivers seeking improved handling, precise control, and everyday comfort.
Developed through extensive road and track testing, the BR Series represents BC Racing’s most versatile coilover platform. It is engineered to offer an optimal compromise between spring rates, damper valving, ride height adjustment range, and top mount design, making it suitable for a wide range of driving styles and applications.
This setup features a true rear coilover configuration, ensuring improved rear suspension response and consistent damping performance compared to OEM-style rear shock and spring arrangements.
