KW DDC Plug & Play Electronic Damping Coilover Kit – Porsche 911 (997) Carrera 4 / 4S / GTS / Turbo Coupe | PASM Compatible | Height Adjustable | Made in Germany | Limited Lifetime Warranty

The KW DDC (Dynamic Damping Control) Plug & Play Coilover Kit for the Porsche 911 997 Carrera 4, 4S, GTS, and Turbo Coupe is KW's most advanced coilover solution for the 997 — a complete height-adjustable coilover kit with fully electronic damping control that integrates directly with the factory PASM (Porsche Active Suspension Management) system via a plug-and-play wiring harness. The DDC system allows the driver to adjust damping force electronically from inside the cabin using the factory PASM switch — no manual adjustment at each corner, no additional controller required. The Porsche 911 997 is one of the most celebrated sports cars ever produced — a rear-engine, rear-wheel-drive (or all-wheel-drive in Carrera 4/4S/Turbo specification) platform with a dedicated enthusiast community that demands the highest level of suspension performance and refinement. KW automotive is the market leader in performance coilover manufacturing — a German manufacturer with over 20 years of experience developing individual suspension solutions for road and motorsport use, with every KW coilover kit developed and manufactured exclusively at their headquarters in Fichtenberg, Germany. Backed by KW's Limited Lifetime Warranty.

Key Features:

• DDC (Dynamic Damping Control) — KW's fully electronic damping control system — adjusts damping force electronically at all four corners simultaneously via the factory PASM switch — no manual adjustment required at each corner
• Plug & Play PASM integration — integrates directly with the factory Porsche Active Suspension Management (PASM) system via a plug-and-play wiring harness — uses the factory PASM switch for damping adjustment — no additional controller or wiring modification required
• Height adjustable — ride height adjustment via the lower spring perch — set the correct ride height for your specific 997 build and driving use
• Covers Carrera 4 / 4S / GTS / Turbo Coupe — correct for the all-wheel-drive 997 Carrera 4, Carrera 4S, GTS, and Turbo Coupe variants
• Application-specific development — engineered specifically for the Porsche 911 997 — correct spring rates, damper valving, and geometry for the 997's rear-engine layout and all-wheel-drive suspension geometry
• Made in Germany — developed and manufactured exclusively at KW's headquarters in Fichtenberg, Germany — exceeds OEM quality standards
• KW Limited Lifetime Warranty — backed by KW's Limited Lifetime Warranty
• KW quality — over 20 years as the market leader in performance coilover manufacturing — trusted by gearheads, automobile manufacturers, and reputable tuners worldwide

DDC — Dynamic Damping Control Technology:

KW's DDC (Dynamic Damping Control) system uses electronically controlled dampers that adjust damping force in milliseconds based on driver input via the factory PASM switch. Unlike manual coilovers that require the driver to physically adjust each corner's damping dial, the DDC system adjusts all four corners simultaneously and instantaneously from inside the cabin. The Plug & Play integration with the factory PASM system means the DDC coilovers respond to the factory PASM switch positions — the driver uses the same switch they already know to select between comfort and sport damping modes, with KW's DDC system delivering the correct damping force for each mode. This integration preserves the factory PASM functionality while delivering KW's superior coilover performance and height adjustability.

PASM Integration — Why It Matters for the 997:

The Porsche 911 997 with PASM uses an electronically controlled suspension system that adjusts damping force based on driving conditions and driver-selected mode. Standard aftermarket coilovers that replace the factory PASM dampers require the PASM system to be disabled or bypassed — triggering warning lights and losing the factory PASM functionality. KW's DDC Plug & Play system integrates directly with the factory PASM wiring — the PASM system continues to function correctly, the factory switch continues to work, and no warning lights are triggered. The result is a coilover kit that delivers KW's performance and height adjustability while preserving the factory PASM integration that 997 owners expect.

997 Carrera 4 / 4S / GTS / Turbo — Platform Context:

The Porsche 911 997 generation (2004–2012) represents one of the most refined expressions of the 911 formula — a rear-engine sports car available in rear-wheel-drive (Carrera/S) and all-wheel-drive (Carrera 4/4S, Turbo) configurations. The Carrera 4, 4S, GTS, and Turbo variants use Porsche's all-wheel-drive system alongside the 997's sophisticated suspension geometry — a combination that demands application-specific coilover development to correctly address the AWD system's suspension geometry requirements. KW's DDC kit is engineered specifically for these AWD 997 variants — correct spring rates, damper valving, and geometry for the Carrera 4/4S/GTS/Turbo's specific suspension layout.
