DSC Sport to Introduce Innovative Suspension Technology at PRI in Indianapolis

The DSC Sport control computer uses a state-of-the-art DSP microcontroller to process the control algorithms used to respond to inputs, changing the shock valving in less than 3 milliseconds. This technology for electronic shock absorbers allows for better tire traction, improved performance and handling, improved car comfort, different setups for corner entry and exit, and unique rain setups.

“This is an absolute industry first,” DSC Sport CEO Michael Levitas said. “We are the only true active ECU that controls the suspension in real and predictive time.”

DSC Sport technology can be used for street and race car applications.

The DSC Sport computer can control all electronic shock absorbers, including OEM equipment. But its true power is unlocked when paired with Tractive suspension that includes the new DDA (Dynamic Damping Adjustment) valve technology.

The DDA valve responds in 5 to 10 milliseconds, a Tractive exclusive. Other manufacturers’ valving responds at an average of approximately 25 to 100 milliseconds depending on the high-speed rate. The DDA is unaffected by piston speed.

The time savings produced by the DSC Sport control computer and DDA valve technology represent 6 inches of track at 125 mph, a huge advantage over the span of a race.

DSC Sport software uses advanced predictive control strategies to adjust the valving based on data from the car’s onboard CAN data system and G sensors. By using the onboard CAN data, the DSC Sport control computer eliminates the need for extra sensors added to the car and the expense of a wiring harness.

Tractive DDA valve technology allows for an instantaneous, continuous, reproducible change of damping, far superior to the pre-programmed, fixed damping available on the market today. The DDA valve has been designed to take all appearing side loads without being functionally stressed under the most severe mechanical conditions.

“This is a game changer for chassis setup,” Levitas said. “It used to be if you want your car to handle like a sports car, it had to ride like a sports car. This will never be the case again.”

Maryland-based DSC Sport and Dutch company Tractive have worked for over three years to design and develop the state-of-the-art bi-directional, internal valve to adjust compression and rebound damping in the Tractive DDA system. Extensive calculation, simulation and engineering were mated with the real-world racing experience of TPC Racing, a longtime championship-winning team in North American road racing, including the Porsche GT3 Cup Challenge by Yokohama sanctioned by IMSA. 

“We are a technical pair made in engineering nirvana,” said Levitas, who also owns and drives for TPC Racing. “DSC Sport and Tractive are worldwide exclusive partners, and we’re ready to show everyone.”

Tractive considers suspension to be an art, combining engineering, development, experience and attention to the fine details to create a high-end, functional and beautiful product. 

DSC Sport control computers and Tractive DDA systems currently are offered for Porsche (2000 to present models), Nissan GTR and Dodge Viper/SRT. BMW M Series and Audi R and S series and other street and racing vehicles will follow as demand grows. TPC Racing will use the IMSA-approved DSC Sport control computer and Tractive DDA system in Porsche GT3 Cup Challenge USA by Yokohama competition starting in 2015.
