The B9 A4 arrived from the factory as a precision instrument calibrated for the widest possible audience. The ride quality, the steering, the ride height, all of it tuned to satisfy the majority. You are not the majority. You bought the A4 because it has a chassis worth developing, and that starts with the suspension.
The KW V3 puts you in control of two separate damping circuits. Compression stiffness handles how the car responds to road inputs. Rebound stiffness handles body motion and corner exit stability. Adjust each independently until the B9 A4 rides and handles the way you need it to, not the way Audi's market research said it should. This is the last coilover a B9 A4 owner ever needs to buy.
