CTS Turbo Audi B9/9.5 A4/S4/A5/S5/Allroad Lowering Springs

CTS Turbo is proud to announce our lowering springs for the Audi B9/9.5 A4/S4/A5/S5/Allroad. 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. We designed our springs for the street, focusing on handling, braking and responsive characteristics, but without making the ride harsh compared to other manufacturers. We engineered our springs in-house and tested them thoroughly before being released, where our testing showed no detriment or deterioration to the OEM strut from long-term use. You can be confident our springs will maintain performance for many years to come. Lowering your car also gives it an aggressive look with the added benefit of reducing the wheel gap and getting closer to that “flush” look, but without compromising daily drivability. DDC compatible: Our springs are compatible with DCC. Our springs couple very well with dynamic damper control, maintaining the ride characteristics between the different modes.
