KW DDC Plug & Play: The electronic coilover suspension for the Porsche 911 (997 & 991) with PASM
The Porsche 911 is an undisputed icon of the sports car world, capturing the imagination with its timeless lines and distinctive boxer sound for generations. Since 1963, this continuous heritage has defined precision engineering made in Germany. With the introduction of the 997 generation (2004–2012), PASM became standard equipment on the Carrera S, a legacy seamlessly continued by the succeeding 991 generation (2011–2019).
While the factory PASM effortlessly balances long-distance comfort with sharp driving dynamics, the KW DDC Plug & Play coilover suspension serves as the ultimate upgrade. It integrates flawlessly with the factory control units, enhances both dynamic handling and ride quality, and retains full OEM functionality. Additionally, the entire system is fully reversible, ensuring the vehicle's originality can be restored at any time.
Only the best for your 911

The factory suspension
Although the factory PASM damper system is a well-engineered concept, it encounters its limits in real-world driving. The Comfort mode often feels too soft, while the Sport mode becomes uncompromisingly harsh. Drivers pushing the car to its limits will find the standard suspension lacks absolute precision, while those seeking a relaxed long-distance cruise will miss the necessary ride comfort. Upgrading to a conventional coilover suspension may solve the performance deficit, but it almost always forces the deactivation of the PASM. As a result, the 911 loses its adaptive driving modes and a vital part of its technological identity. A true upgrade shouldn't eliminate the car's versatile character; it should elevate it. That is why we developed the KW DDC Plug & Play.
KW DDC Plug & Play
The KW DDC Plug & Play adaptive coilover suspension delivers 100% compatibility with the Porsche 911 (997 & 991) PASM system. Utilizing the original factory connectors, installation is seamless—the vehicle’s electronics recognize the suspension immediately without requiring any software coding. The original Comfort, Normal, and Sport modes remain completely intact, offering optimized and noticeably more harmonious performance. Additionally, the dirt-resistant trapezoidal thread enables continuous height adjustment within the TÜV-certified range. This setup was engineered through sophisticated simulations on our in-house driving dynamics rig and perfected through extensive real-world track and road testing.

Technical component reportWhy is PASM compatibility essential for your suspension upgrade?
PASM (Porsche Active Suspension Management) is the high-performance electronic damping system that keeps your Porsche’s ride and handling perfectly balanced in real time. Most aftermarket coilovers force you to disable this technology. The KW DDC Plug & Play eliminates this tradeoff. By maintaining full PASM functionality, it preserves the car’s original electronic infrastructure while delivering a significant performance boost. It is the only way to enjoy state-of-the-art suspension dynamics without losing the technological identity of your Porsche 911.
For which Porsche 911 models (997 and 991) is the KW DDC Plug & Play available?
This product is precision-engineered for the following Porsche 911 generations. 997 Series: Carrera 2, 2S, 4, 4S, 4GTS, Turbo, and Turbo S (Coupé/Cabriolet). 991 Series: Carrera/S/4/4S/GTS, Targa 4/4S (Coupé/Cabriolet; covers all drivetrain variations, including PDCC and facelift models). 991 Turbo/S: All Coupé and Cabriolet variants, including models equipped with the factory lift system.

How is the KW DDC Plug & Play installed?
The KW DDC Plug & Play replaces your vehicle’s factory dampers, integrating directly with the onboard electronics via the original OEM connectors. The system is recognized by the vehicle immediately; no software coding or reprogramming is required, and the full range of PASM functionality is retained. Note: To ensure optimal driving dynamics and a precise ride-height setup, we recommend having the installation performed by an authorized KW automotive dealer. This ensures that your vehicle is calibrated to the highest performance standards.
What happens to the vehicle registration after installing the KW DDC suspension?
The KW DDC Plug & Play is supplied with a technical component report. This document contains vehicle-specific lowering specifications, installation requirements, and technical guidelines. Based on this report, the suspension setup can be seamlessly registered in the vehicle’s official documentation. Important: Registration requirements and local regulations may vary by country. If you have any questions regarding local compliance, we recommend consulting with your local testing authority or authorized inspector.
How does the KW DCC Plug & Play system change the handling of the Porsche 911 997?
The KW DDC Plug & Play has been developed exclusively for the 997, enhancing its factory performance. The optimized damper characteristic curve delivers noticeably sharper steering precision. In Comfort mode, the vehicle feels more responsive without compromising on its renowned long-distance comfort. The body remains steadier and bumps are handled with ease. In Sport mode, the 911 transforms into a dynamic driving machine. You will experience more direct handling and significantly reduced body roll when taking fast consecutive corners, as well as enhanced cornering stability, supported by the custom lowering which optimises the vehicle’s center of gravity.
Does the KW DDC Plug & Play also improve the handling of the newer Porsche 911 (991) models?
Thanks to its lightweight construction, the 991 already offers impressive driving dynamics. However, the standard suspension tuning does not fully exploit the 911’s potential. This is where the KW DDC Plug & Play comes in, significantly optimizing the damper response curve while fully integrating with the standard PASM electronics. In the high-performance Turbo and GTS variants in particular, the improved vehicle control ensures a confident driving experience, with reduced body roll and increased traction, especially at high engine torque.
