Porsche 991 Tractive DDA RT Coilovers


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/endurance races with no sacrifices on performance or compliance.




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 the 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.

Road/Track Xtreme (RTx) package offers all the benefits of the RT package with an added advantage: the remote canister featuring high/low speed compression adjustment. The RTx package is designed for hardcore competition racers, and it is absolutely vital for endurance racing. The additional housing volume for nitrogen and oil provides greater heat dissipation, allowing for consistent damping over longer periods of use. For the GT car applications, the RT kit will utilize an aluminum body coilover.
