The 21-page guide can be perused in the gallery below and contains all of the standard features, colors, options codes, descriptions. Generally everything you might want to know about the 'Stang is there, other than its price or power. It even shows off the available wheel designs.
The guide finally gives away the contents of the Performance Package for the EcoBoost and GT trims. The EcoBoost's package includes: A larger rear sway bar, new chassis tuning, larger brake rotors, 19-inch black wheels, retuned driver assistance systems, an aluminum dash panel, added gauge pack, 3.55 limited slip rear differential, larger radiator, heavy-duty front springs and spoiler delete. When the options pricing leaked, it indicated the package would cost $1,995. If that is the case, it seems like quite a deal.
For the GT trim, the performance package includes most of the same upgrades from the EcoBoost plus a strut tower brace, K Brace, a 3.73 Torsen limited-slip rear differential and – only for cars with a manual gearbox – Brembo six-piston front brakes. The leaked options pricing indicated that package would sell for $2,495.
If you are in the market for the 2015 Mustang, this ordering guide is a must-read. Happy planning.
