Description
For a 2014–2018 Audi RS7 (4G) being developed beyond stock suspension behavior, KW V4 provides a more deliberate foundation for ride height, body control and tire management.
KW V4 expands the tuning window with low-speed rebound plus separate low- and high-speed compression adjustment. That additional compression control is valuable when a build needs to distinguish slower platform motions such as pitch and roll from sharper wheel inputs over curbing, joints and bumps. The application-specific calibration is intended to give the chassis a more deliberate response than a one-size-fits-all suspension combination.
Why Choose the KW V4 for This Application?
Choose the V4 when the setup is developed enough that high-speed and low-speed damper events need to be treated differently. This is especially useful when ride quality over sharp impacts must coexist with stronger pitch and roll control.

Enthusiast Setup Perspective
A good installation should leave enough travel for the road or circuit being used. Chasing maximum lowering at the expense of bump travel can work against the very grip and control this system is intended to provide. After installation, establish ride height and alignment first, then make damper changes in small increments and record them so the effect of each adjustment remains clear.
Important KW Fitment Notes
- KW Note 2: Height adjustable front and rear axles (front axle threaded strut housings, rear axle adjustable springs + dampers)
- KW Note 8: Not for vehicles with automatic self leveling control
- KW Note 67: Valving is adjusted by adjustment knobs, rebound is only adjustable if the top of the piston rod is accessible. This will depend on the design of the vehicle.
- KW Note 88: Electronic damping control has to be deactivated. Deactivation kit is included in the delivery.
Fitment note: Specifications above are tied to the exact KW part number shown and the application data in the supplied KW jobber sheet. Confirm the vehicle's drivetrain, factory electronic suspension, axle weight and any listed hardware requirements before ordering.
