Porsche 911 (997) C4 / C4S / Turbo / Turbo S Track Line Stand-alone electronic suspension kit
TracTive’s stand-alone semi-active electronically adjustable shocks deliver advanced track-focused suspension technology for any high-performance vehicle. This complete kit includes a control unit, touchscreen display, and wiring harness, providing full control over your car’s handling dynamics.
Patented DDA Valve Technology
Each damper is equipped with TracTive’s Dynamic Damping Adjustment (DDA) valve:
6–10 millisecond response from full soft to full hard
Exceptional stability, reproducibility, and precision
Trusted by high-end OEMs and professional racing teams
Factory settings provide optimal damping levels and adjustment ranges, with optional fine-tuning available.
Intelligent Motion Control
An integrated g-sensor monitors roll, pitch, and dive motions, installed close to the vehicle’s center of gravity for precise real-time adjustments. Factory calibration ensures top performance and can be updated if required.
Touchscreen Interface & Customization
The touchscreen display allows drivers to:
Adjust front and rear damping in 5 levels
Control roll resistance in 5 levels
Tune pitch and dive in 5 levels
Save driver-specific setups and make on-the-fly adjustments
A remote adjustment knob is also included and can be centrally mounted for easy access.
Track-Proven Hardware
These shocks share hardware with TracTive’s track kits:
Internal DDA valve replaces manual rebound adjuster
Eibach springs with infinite ride height adjustment via platforms or separate adjusters
46mm high-flow pistons, low-friction seals, and 16mm super-finished, induction-hardened CrMo-steel piston rods
Hardened aluminum alloy shock bodies for lightweight thermal stability
Steel inverted McPherson struts with 38mm high-flow pistons for minimal stiction and maximum stiffness
Motorsport-Grade Top Mounts
All track kits include application-specific top mounts:
Inverted struts: Adjustable camber and/or caster
Non-McPherson shocks: Solid top mounts
