When using your factory "Mag-Ride" on an RS3 and TTRS it is easy to "over spring" the dampers and have them go into what is often described as “panic mode”. When this happens the dampers go full hard and the car will get very bouncy and unpredictable in corners. These springs are not intended for vehicles where cornering capabilities are a are a concern.
