Description
The value of KW V4 on a 2021+ Porsche 911 (992, PASM) is not just the change in stance; it is the ability to place the chassis in a more controlled operating window for the way the car is actually driven.
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. On a performance-focused chassis like this, suspension tuning becomes increasingly valuable as tire grip, alignment and braking capability are raised.
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.
Key Features
- Low-speed rebound adjustment

Enthusiast Setup Perspective
For an enthusiast build, the practical benefit is consistency. A controlled platform makes steering, braking and tire behavior easier to read, which matters as wheel width, tire grip and alignment become more aggressive. 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 1: Height adjustable on the front and rear axles (threaded strut housings)
- 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.
- KW Note 423: V4 suspension struts / dampers made of aluminum or combined axle-wise from galvanized steel (FA) and aluminum (RA)
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.
