“To an engineer, it's simple physics. To an SRT Viper Track Pack customer, it's simply incredible.” This is how Chrysler describes the new Track Pack that it is now available for the 2013 SRT Viper. According to the official press release, at the heart of this package is a state-of-the-art braking package.
If on the standard version of the SRT Viper, the brake cooling ductwork are designed to promote maximum cooling and downforce, the Track Pack takes things even further and replaces the replacing conventional thin-post cooling vanes with exotic curved vanes. Moreover, the Track Pack brake rotors draw in from the center, near the hub and the curved vanes then work to pump air outward, cooling the rotor surfaces in a more active manner.
Furthermore, Chrysler says that the Track Pack brakes were designed to be especially effective on the track in the 100 mph-plus range. Due to this, at slower speeds, the cooling advantage dissipates to fall back in line with the standard car. The Track Pack also makes the car lighter, as it is with 32 pounds lighter than the one found in the standard car.
Track Pack owners will save 62 pounds of unsprung weight compared to a standard SRT Viper. Under the hood, the car keeps its impressive 8.4-liter V10 engine delivering 640 hp and 600 lb.-ft. of torque, mated to the Tremec TR060 six-speed manual transmission. "A customer's perception of the brake system depends very much on the way the driver uses the car," notes Graham Henckel, Chief Engineer of the SRT Viper. "The faster you go, the greater the advantage."
