NASHVILLE, Tenn. (Nov. 5)—Bridgestone/Firestone Vehicle Systems, a unit of BFS Diversified Products L.L.C., will produce a new aftermarket suspension called Praxis-brand Advanced Suspensions system, the firm announced Nov. 5 at the SEMA show in Las Vegas. The new system will make its debut on the Subaru WRX. "Praxis systems represent our company's effort to bring technology and quality to the aftermarket consumer," said John Vincent, managing director, Bridgestone/Firestone Vehicle Systems. "Unlike individual components available in the marketplace, Praxis suspensions have been developed as a system, balancing key performance elements from tire to chassis." The Praxis system interacts with the driver through a cockpit-mounted module, that provides the driver with the choice of three fully engineered and tuned operating modes—touring, sport or track.
