Road & Track compiled a list of evidence that points toward a more robust performance option. The current Mustang GT Performance Pack includes things like staggered wheels and tires, six-piston Brembo brakes, new front springs, a larger radiator, a limited-slip differential and more. The upgrades to the Camaro 1LE are roughly the same, but somehow Chevy seems to eek out more performance from its parts than Ford has with the Camaro, especially with a car like the ZL1 1LE (internal option codes are sexy).
A new Mustang was spotted wearing a new set of wheels wrapped in Michelin Pilot Sport Cup 2 tires, some of the stickiest street tires available. There have also been some leaked order guides that hint at an even greater performance pack. Still, we've been burned by leaks before. There's no comment from Ford on the matter, so we'll have to wait for the Mustang to hit showrooms before we know any more.
