KW V3 Inox-Line Coilover Suspension Kit – Porsche 997 C4 / C4S / Turbo – With PASM

KW V3 Inox-Line coilover suspension kit for Porsche 911 997 Carrera 4, Carrera 4S and Turbo with PASM. Independently adjustable compression and rebound damping for precise handling, improved road feedback and track-ready performance.

Product Description

The KW V3 Inox-Line Coilover Suspension Kit is engineered for drivers who demand the highest level of suspension control and performance from their Porsche 997.

Designed specifically for Porsche 997 Carrera 4, Carrera 4S and Turbo models equipped with PASM, the KW Variant 3 system replaces the factory dampers with a fully adjustable motorsport-derived suspension solution while maintaining compatibility with the vehicle's chassis architecture.

KW’s independent compression and rebound damping adjustment allows precise tuning of the suspension characteristics to suit road driving, fast road use or track performance. Rebound damping controls body movements and ride comfort, while adjustable compression damping allows you to fine-tune cornering stability and grip.

Manufactured from KW’s proprietary Inox-Line stainless steel, the coilovers provide exceptional corrosion resistance and long-term durability — ideal for year-round driving conditions.

The result is improved steering precision, reduced body roll and enhanced traction, allowing the Porsche 997 chassis to perform at its full potential.
