 Ford Mustang Boss 302 Laguna Seca, 2012

Ford Mustang Boss 302 - a street-legal race car in its own right? Pull out everything that doesn't make it go faster and add in more of what does. The result is the limited-production Ford Mustang Boss 302 Laguna Seca package - the ultimate 2012 Boss, named to commemorate the first-place Boss 302 finish at the 1970 Trans-Am series opener.

Chassis enhancements
Ford Mustang Boss 302 Laguna Seca cars are powered by the same smooth, high-winding 440-hp 5.0-liter V8 as the standard Boss, since the engine was already tuned specifically for road racing. Instead, engineers turned their attention toward delivering power to the ground most efficiently, and getting the car around a track in the quickest possible time.

Ford Mustang Boss 302 Laguna Seca cars eliminate the rear seats, instead adding a cross-car X-brace that couples the structure between the rear wheels. The brace offers chassis stiffness improvements of as much as 10 percent and allows the suspension tuning - precisely calibrated by Mustang team members - to better do its job.

Standard Recaro front seats were designed by Ford SVT in cooperation with Recaro for high performance Mustang models, and are shared between the Boss and GT500. An Alcantara-covered race steering wheel provides a solid grip for hard cornering.
Engine power routes through a six-speed close-ratio manual gearbox to a standard 3.73-ratio Torsen limited-slip differential, helping the revised rear suspension deliver maximum torque and traction under the punishing conditions encountered on the track.

Higher spring rates and a larger rear stabilizer bar - all upgraded over Boss specifications - help generate unrelenting grip. And drivers can dial in exactly the level of shock stiffness a particular track requires using the four standard, independently adjustable dampers with Laguna Seca-specific valving.

The final touch for a proper race car was to add the proper wheels and tires: 
Ford Mustang Boss 302 Laguna Seca models use lightweight 19-inch alloy racing wheels in staggered widths: 9 inches in front, 10 inches in the rear. R-compound ultra-high-performance tires, 255/40ZR-19 in the front, 285/35ZR-19 in the rear, maintain contact with the pavement - a job that ended up being trickier than expected.

While standard Ford Mustang Boss 302 cars get vented brake dust shields to help cool the rotors, Laguna Seca models receive Ford Racing front brake ducts that force outside air directly onto the 14-inch vented front rotors, helping to eliminate brake fade and ensure hard, repeatable late braking on the track. Combined, the braking changes help refine the sense for drivers of being directly connected to the pads - an essential edge during car-to-car combat on a road course.

Added up, the further improvements to Ford Mustang Boss 302 Laguna Seca result in the best-handling Mustang ever, with more than 1.03 g of lateral acceleration, stopping distances shortened by three feet from 60 mph over Boss, 0-60 acceleration improvements of one tenth of a second, and an overall expected lap time improvement of one to two seconds over the standard Boss on a typical road course.

Styling evokes racing, improves aerodynamics
As a race car should, Ford Mustang Boss 302 models with the Laguna Seca package look like nothing else on the road. A bright red C-stripe offsets either Black or Ingot Silver paint, and is complemented by a red roof panel. Red also sets off the front grille, mirror caps and rear pedestal spoiler, while Laguna Seca rear badging and unique two-tone red and silver wheels complete the transformation.

Adding both to appearance and aerodynamics, an aggressive front splitter for track use adds downforce at the front of the car, while helping channel air under and around the car. At the same time, air impacting the front end is funneled into the radiator and brake ducts, supporting cooling even under grueling race conditions.
At the back, a large rear spoiler is sized to exactly complement the effect provided by the front splitter and underbody aero treatments, with the combination adding as much as 90 pounds of downforce at 140 mph.
