Description
KW V1 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 V1 combines threaded ride-height adjustment with an application-specific, factory-set damper calibration. It is intended for drivers who want the response and stance benefits of a complete coilover without external damping controls. 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 V1 for This Application?
Choose the V1 when you want a complete KW coilover and adjustable stance but prefer KW to define the damper calibration. It is the simplest route into the KW coilover range and avoids adding setup decisions the car may not need.

Enthusiast Setup Perspective
This setup makes the most sense when the suspension is being treated as part of a complete package. Final ride height, alignment, tire choice and available bump travel should be considered together rather than setting the car as low as possible. For a road-driven car, preserving usable bump travel and sensible alignment is usually more important than using the full available lowering range.
