2015 Ford Mustang Offers Three Brake Systems

One big change for the 2015 Ford Mustang is its fully-independent rear suspension, the first for a Mustang. But while we already knew the basics of the 2015 Mustang’s chassis, Ford has now provided more details on the different brake and suspension setups for various Mustang models, including the optional Performance Pack that costs $1995 on EcoBoost models and $2495 on GT models.

There are three brake packages available, depending on model and equipment. The first is for the standard Mustang V-6 and Mustang EcoBoost, and includes 12.6 in rotors front and rear; two-piston, floating calipers in front; and single-piston calipers in the rear. Mustang EcoBoost models with the Performance Pack and standard Mustang GT models are upgraded to four-piston fixed calipers in front; single-piston calipers in the rear; and 13.9 in rotors in front and 13 in rotors in the rear. The range-topping Mustang GT with the Performance Pack has six-piston Brembo calipers front; single-piston calipers rear; and 15 in rotors up front and 13 in rotors in the rear.

In addition to the upgraded brakes, both EcoBoost and GT Performance Packs get retuned springs, bushings, and monotube rear dampers, a thicker rear sway bar, and a K-brace connecting the rear strut towers to the bulkhead. The ABS, stability control, and power steering systems are also retuned, the interior gains extra center gauges, and extra engine cooling capability is added for better durability on the track. Additionally, EcoBoost Performance Pack cars have a 3:55:1 final drive ratio, and GT Performance Pack cars have a 3:73:1 final drive ratio with a Torsen differential.

All of this should make for some impressive handling and stopping power to go with the 2015 Ford Mustang’s recently announced horsepower and torque numbers. The car’s base V-6 makes 300 hp and 280 lb-ft of torque, the 2.3-liter turbocharged EcoBoost four-cylinder makes 310 hp and 320 lb-ft of torque, and the 5.0-liter V-8 in the Mustang GT has 435 hp and 400 lb-ft of torque.

The aforementioned Performance Pack is only available on 2015 Ford Mustang coupe models, on all trim levels other than the base Mustang V-6. A Mustang EcoBoost with the six-speed manual and the Performance Pack costs $27,990, and a manual Mustang GT with the package adds up to $35,420, both with destination. All versions of the 2015 Ford Mustang will go on sale later this fall.

This for me this is almost as important as the horse power upgrade and IRS. Having owned a few Ford products in the 80s and90s and watching a friend of mine valiantly try to stop his 71 Torino GT with 4 drum brakes, its been my opinion that poor braking performance has always been the Achilles heel of Ford products.Though expensive I hope somewhere in the bowels of Dearborn some brave soul is allowed to work on carbon ceramics for yet some unnamed SuperStang!
i paid $1100 or so to get new ford racing's 4-piston fixed brembos, 14" rotors, and stainless steel brake lines (front and rear) on my 2006 mustang GT. Also had to buy new wheels so they could fit over the BBK; which is admittedly not the best for serious racers, but is the cheapest BBK out there.
$2500 performance pack for the 6-piston 15" rotors and all the other goodies is a smoking deal and easy choice for anyone doing road racing/track days. 
the only issue i could possibly see is aftermarket wheel fitment but i am sure it won't be too bad given time.
