SRT Viper Track Pack 2013

H SRT ανακοίνωσε ότι η νέα Viper θα είναι διαθέσιμη και με το Track Pack πακέτο. Το πακέτο είναι διαθέσιμο τόσο στην απλή Viper έκδοση όσο και στη Viper GTS και για να αυξήσει την κάθετη αεροδυναμική πίεση και τη καλύτερη ψύξη των φρένων, διαθέτει νέους αεραγωγούς που κρυώνουν τα νέα μεγάλα φρένα της Brembo των οποίων οι δίσκοι ζυγίζουν 3,6 κιλά λιγότερο. Συνολικά το Track Pack αφαιρεί 14,5 κιλά από τη στοκ Viper.

Το βάρος μειώνεται περαιτέρω αφού η Viper Track Pack φορά νέες ζάντες με ελαστικά Pirelli P Zero Corsa, που ζυγίζουν συνολικά 28,1 κιλά λιγότερα. Το πακέτο διαθέτει επίσης ρυθμιζόμενο traction control με 4 ρυθμίσεις και επαναπρογραμματισμένο σύστημα ευστάθειας.

2013 SRT Viper Track Pack.

SRT® Viper customers who elect to extract the highest degree of track performance from their vehicle can opt for the Track Pack. At the heart of this sophisticated suite of subtle upgrades is a state-of-the-art braking package that improves upon the Viper’s already impressive brake cooling properties.

All SRT Viper trim levels are equipped with carefully refined brake cooling ductwork designed to promote maximum cooling and downforce. Track Pack brake rotors take this cooling theory to the next level, replacing conventional thin-post cooling vanes with exotic curved vanes.

Track Pack brake rotors draw in from the center, near the hub. The curved vanes then work to pump air outward, cooling the rotor surfaces in a more active manner compared to the passive airflow in a conventional thin-post rotor.

“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.”

Track Pack brakes are designed to be especially effective on the track in the 100 mph-plus range. At slower speeds, the cooling advantage dissipates to fall back in line with the standard car. However, the Track Pack’s weight advantage is realized at any speed: at eight pounds less per rotor, the Track Pack brake setup is 32 pounds lighter than in the standard car. Factor in the lightweight wheels and lightweight tires, and the weight savings is considerable: in the most optimal case, Track Pack owners will save 62 pounds of unsprung weight compared to a standard SRT Viper.

Reducing unsprung weight pays dividends in triplicate on the track. Unsprung weight must be carefully managed to ensure optimal cornering and launch characteristics. The less unsprung weight a vehicle carries, the less damping is required to keep the tires in contact with the road surface. Reducing rotational inertia also means reducing the amount of work that must be done to get the wheels, tires and brake rotors up to speed when launching.

To an engineer, it’s simple physics. To an SRT Viper Track Pack customer, it’s simply incredible.
