Available for all 996, 997, 987, 991, and 981 models; the Road/Track (RT) package is the introductory level coilover kit for the Tractive DDA line. It features the patented DDA damper, swift springs with rates of your choice, and billet aluminum top mounts/camber plates on all four corners. The RT package is suitable for street driving, DE days, club racing, and professional sprint races (

All Tractive DDA packages feature the patented DDA valve. The DDA valve offers the fastest, most dynamic, and most consistent damping range of any electronic damper on the market. Responding to commands from the DSC controller in only six milliseconds, the Tractive DDA allows for a more sophisticated tuning file, relying less heavily on predictive control strategies.

The mechanical build also sets the Tractive DDA line apart from all other class competitors. Offering he finest guide seal, piston, and shim stack arrangement on the market (.01mm guide clearance), the DDA damper withstands heavy load changes with no signs of hysteresis or stiction. The result is the world’s most dynamic suspension system that provides a previously unheard of combination of race-winning performance on the track and daily driver comfort on the street.

DSC stands for Dynamic Suspension Control. Using an algorithm developed out of years of professional race data, DSC adjusts the damping level of each individual shock in virtually real time. The result is an active suspension setup that provides more grip to the tire, greater stability and ride control, and increased comfort for all driving styles and road conditions.

DSC Sport allows drivers to custom tune their suspension by creating various tuning maps within the DSC Sport Tuning Software. Users may wish to create custom maps for specific tracks or roads, unique rain set ups, or to improve compatibility with other aftermarket products and vehicle setups.
