NASHVILLE, Tenn. (Nov. 7, 2002) — Bridgestone/Firestone Vehicle Systems, a business unit of BFS Diversified Products L.L.C., has introduced an aftermarket suspension system it said allows a driver to control performance with the “push of a button.”
The company claims its Praxis Advanced Suspensions are the first aftermarket applications utilizing Dual Rate Air Spring technology and the Intelliride control-system developed by Firestone Industrial Products, another operating unit of Bridgestone/Firestone.
John Vincent, managing director of Bridgestone/Firestone Vehicle Systems, said the “Praxis systems represent our company's effort to bring technology and quality to the aftermarket consumer. Unlike individual components available in the marketplace, Praxis suspensions have been developed as a system, balancing key performance elements…from tire to chassis.
“The automotive enthusiast simply has to push a button to change the performance of the vehicle. Most enthusiasts are not engineers. We did the engineering for the user, so they can take the driver's seat and enjoy the performance.”
The Praxis system interacts with the driver through a cockpit-mounted control module that provides the driver with a choice of three fully engineered and tuned operating modes: touring, sport or track. According to the company, vehicle performance and appearance are transformed without having to physically swap out parts, translating to a cost savings.
In touring mode, the company said, the Praxis suspension system has been engineered to replicate the character of the factory-produced vehicle.
In sport mode, the vehicle transforms to accommodate a more aggressive use by automotive enthusiasts. Handling response is dramatically sharpened to suit spirited driving situations, BFS said.
The track mode setting radically transforms the vehicle, lowering ride height 50 millimeters, the company said, while increasing damping performance to precisely control body motions. Spring rate is nearly doubled by adjusting the remote reservoir volume.
The Praxis suspension system debuted on the Subaru WRX platform at the Specialty Equipment Market Association trade show in Las Vegas. BFS said that final marketing and distribution arrangements are expected to be completed by year-end for product release to the U.S. marketplace in the second half of 2003.
