I think you might be confusing the 3.73 rear end gears, which is a stand-alone option, with the track-pack option which includes the 3.73 gears as well as the brake and suspension upgrades, spoiler delete, and ESC tuning. You can go to Ford's web site and configure your own Mustang and see how these options differ.

Incorrect. The 3.73 gears are not a stand alone option. The screenshot below shows what the non-trackpack 3.73 rear axle package includes. Some call this "track pack I" and the full track pack "track pack II".

However, don't all GTs have dual piston calipers? Why do they even mention this?

Im very excited... The rumbling V8 combined with what i call the "stage 2" supercharger that gives you 550 hp i love supercharger whine. And akways wanted a 500hp car. Does anyone know how much that add on is??

SirDrums

how hard will you have to push the car to get all of the 550 hp?

just wondering

Hmmmm well you have the car im looking into getting im total noob here. I think i just like the numbers. And its nice for the drag strip.. Ive never owned a mustang and its a scary jump from a 4 cylinder turbo. But i know ive beaten a few im sitting 320 at the wheels and alot lighter.. The extra hp would be a confidence/thrill/adrenaline/morale booster.

Sure i might not use all of that HP... But its nice to know that its there waiting

I stand corrected. Sorry about that.
Indeed, the 3.73 rear axle package does include the ESC and brake upgrades. The track pack includes this plus some additional suspension options (shock tower brace, shock tuning, sway bars, rear control arms, 19-inch wheels w summer HP tires, so spare).
