Description
KW V3 Coilovers – 1989–1990 Porsche 911 (964, Carrera 4) is built for the enthusiast who wants the suspension to become a functional part of the chassis setup, not simply a visual drop.
KW V3 is built around independent low-speed rebound and compression adjustment. KW's current V3 architecture provides 16 rebound clicks and 12 compression clicks, giving an enthusiast meaningful control over chassis support, response and ride without moving into a dedicated motorsport damper. 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 V3 for This Application?
Choose the V3 when the car needs a broader operating window. Independent rebound and compression control makes it easier to balance ride, platform support and tire contact as the build moves between street use and more demanding driving.

Enthusiast Setup Perspective
For mixed street and performance use, start from KW's baseline settings and make changes one variable at a time. That gives the driver a repeatable way to separate genuine setup improvement from simple changes in ride feel. 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.
