Just as with the Boss 302R, unveiled last year and offered in a very limited lot of 50, the new 2012 Ford Mustang Boss 302 Laguna Seca introduced this week gets a tighter suspension and chassis setup, along with aerodynamic improvements and a unique look. Now, at the start of the big Monterey weekend Ford is rolling out a Boss 302 Laguna Seca that celebrates Parnelli Jones' 1970 season-opening victory.
Make no mistake about it, this isn't an appearance package. Everything about the new Boss was tuned for those who want racetrack performance over comfort.

The 2011 Ford Mustang GT's 5.0-liter V-8 engine carries into the Mustang Boss with only breathing changes and more aggressive engine controls. Altogether, the engine makes 440 horsepower (versus the standard GT's 412 hp) and 380 pound-feet of torque.
With a race-duty clutch and short-throw six-speed manual, a 3.73 rear ratio, and limited-slip rear differential, the Boss 302 has the makings of a great track day Mustang. But there's a lot more here that Ford finesses a completely new personality into the Boss as well—by making it sound considerable more savage than the Mustang GT.
Side pipes give the exhaust character
Ford's powertrain team managed to give the new Mustang Boss the sound of a V-8 racecar while keeping it (just barely) street-legal. A special Boss intake has “minimum restrictions,” and the intake has been retuned, while the exhaust has reduced backpressure and was tuned to match the rush of intake noise. Of the four exhaust exits, two are much like the standard Mustang GT, crossing over and exiting at the back, but there are also lower-flow side pipes that produce a lot of sound yet don't carry much exhaust volume. The whole setup is designed in such a way that it can be tuned down for areas that are more restrictive about sound.
Suspension and steering have been retuned as well, with higher-rate coil springs added front and back, matched with softer bushings and a larger rear stabilizer bar. Compared with the GT, the Boss rides 11 millimeters lower in front and 1 mm lower in back. Instead of adding an expensive modern electronically adjustable damper setup, Ford installed shocks that are similar to the original Gabrial shocks offered on the first Boss 302, with adjustment at the top of the shock towers and five different settings that would allow you to crank up feedback at the track then ride home more comfortably.
Traction and electronic stability control systems are different in the Boss to belp take advantage of the more aggressive settings, and it includes a sport mode that allows more aggressive driving before intervening. Even for those planning to use the Boss mainly on the track, think of it as training wheels.
