The fifth series of the Audi A4 station wagon (B9) once again proofs that fancy station wagons are called Avant. From now on, the height-adjustable KW coilover springs are available for the A4 station wagon with all engine types.
Compared to conventional springs, the KW spring kits allow a continuous lowering, similar to coilover kits. When installing, the series springs are replaced by KW springs with level control.

Afterwards, in combination with the series dampers, an individual lowering can be adjusted within the tested adjustment range of 20 – 45 mm.

With conventional springs, this would not be possible. The spring rates harmonize with all driving modes of the optional Audi comfort suspension with damper regulation in the A4 station wagon.
