Roush has come out with a new variant of its ground-pounding 427R. the 427R Trak Pak Mustang is designed for drivers who want to track their road cars on race weekends and such. Naturally, a host of changes have been made which differentiate the Trak Pak from the standard 427R. The 427R's plenty powerful ( 435 hp/400 lb.-ft.), but to make it really track-ready, Roush bestowed the Trak Pack with improved cooling, enhanced chassis rigidity, a fully-overhauled suspension, upgraded 6-piston brakes, and a new aero kit with an optional adjustable rear wing (as shown above). New 18" wheels, extra-sticky rubber, and unique graphics cap off the 427R Trak Pak's imposing look. The interior is similarly upgraded with a performance gauge package, shift light, short-throw shifter, leather sport seats, and aluminum pedals. Roush expects many buyers to use the 427R Trak Pack as a daily driver in addition to flogging it on a closed course, hence the presence of the comfort items like the leather seats. Pricing's been set at $58,245 and production will be limited to 100 cars, which will start becoming available later this summer. Follow the jump for the complete skinny from Roush, which calls the 427R Trak Pak its best-handling Mustang ever.

LIVONIA, Mich. (July 20, 2007) - Jack Roush knows a thing or two about racing and Mustangs. His road racing career includes more than 110 wins and 20 national championships, and this vast expertise is evident throughout the latest special edition Mustang offering from ROUSH Performance - the 2008 ROUSH 427R Trak Pak.

Designed for the daily driver who enjoys pushing his car to the limits on open track days, the ROUSH 427R Trak Pak Mustang has plenty of specialized content to accommodate the unique needs of those who like driving up to the edge on the racetrack in a safe, controlled environment.

With the addition of the intercooled ROUSHcharger* the 427R Trak Pak Mustang has 435 horsepower and 400 lb.-ft. of torque, plenty of power to quickly get up to speed on the straightaways. The cooling system has been enhanced with a black bar high flow front grille and radiator cooling shields. There is a functional strut tower brace under the hood to help strengthen the chassis and decrease unwanted twisting.

The suspension system has been completely revamped to easily manage the twists and turns of a road course. The ROUSH 427R Trak Pak suspension includes adjustable front and rear shocks, front and rear springs, front and rear stabilization bars, front and rear jounce bumpers and adjustable camber/caster plates.

To whoa this pony down ROUSH adds 6-piston front calipers with 14-inch, two-piece slotted front rotors and slotted rear rotors. The brake pads are replaced with high-performance racing quality versions, and the new ROUSH brake cooling system and high temperature brake fluid will ensure that the brakes will be ready when you need them the most.

The ROUSH three-piece aerobody kit gives the car a menacing look as it roars past the other cars on the track, and consists of a front fascia, front chin spoiler and hood scoop. The ROUSH 427R Trak Pak Mustang will also be available with an optional functional, adjustable rear carbon fiber spoiler, which in testing, provided additional rear downforce. The car rides on 18-inch forged wheels painted a dark charcoal and mounted to ultra-performance tires for maximum grip on the racetrack. The functional hood pins, unique graphics and badging add to the overall styling of the car.

Inside the cockpit the driver will immediately notice the addition of the new three-gauge dash pod with engine oil temperature, coolent temperature and a boost gauge. A shift light has also been integrated into this dash pod as well. The ROUSH sport leather seating, short throw shifter with retro-style ball, and four-piece performance pedal kit help to round out the interior styling.

"There is a lot of innovation in these cars that came directly from what we used in my Trans-Am and IMSA racing days and to see it transferred to a street car and for open track use is extremely gratifying," said Jack Roush. "There are no other Mustangs on the market with standard equipment like adjustable camber plates or brake cooling ducts and I fully expect to see this car flex its American muscle and run past the European imports that seem to dominate these types of track events."
"Even though this car has, obviously, a lot of content which was designed for track use, I foresee most owners using this as a 'daily driver' as the handling of the ROUSH 427R Trak Pak Mustang is our best-handling Mustang ever," said Joe Thompson, ROUSH Performance vice-president and general manager. "The handling on this Trak Pak Mustang is truly something amazing."

The ROUSH 427R Trak Pak Mustang went through thousands of miles of testing on the streets and racetracks prior to being approved for production. The ROUSH engineering staff would continually evaluate the functionality and durability of the parts on racetracks such as Road America (Elkhart Lake, Wis.), Gingerman Raceway (South Haven, Mich.), and Hallett Motor Racing Circuit (Hallett, Okla.).

There are just a handful of options available for the ROUSH 427R Trak Pak Mustang, including white electro luminescent gauges, carbon fiber dash trim kit, and the ROUSH rear quarter window louvers.

The ROUSH 427R Trak Pak Mustang has a suggested retail price of $58,245. The vehicle is expected to be available in the late summer, just in time to put some humility into the other drivers prior to the end of the open track season. This car will be limited in production to 100 units.

Current owners of ROUSH Mustangs will be pleased to learn that some of the 427R Trak Pak Mustang components will be available separately. Pricing and component details will be available shortly.
