CTS Turbo Lowering Spring BMW G20 330/M340, G22/G23 430/M440, G42 M240i xDrive

We are proud to announce our new lowering springs for BMW G20 330/M340, G22/G23 430/M440, G42 M240i xDrive. Our lowering springs are designed to deliver the perfect balance between everyday comfort and responsive handling. Our springs significantly reduce body roll, resulting in improved turn-in response and enhanced stability during spirited driving.

Despite the performance-oriented design, ride quality remains comfortable for daily use. Spring rates are carefully selected to complement the factory dampers, ensuring that the car maintains its composure over rough pavement without feeling harsh or overly stiff. Whether you’re carving through corners or cruising on the highway, these springs enhance the overall driving experience without sacrificing ride comfort.

All our springs are made with high-quality SAE 9254/DIN 54SiCr6 Spring Steel Wire, so you can be assured the springs are safe, strong and won’t fatigue with time.
