There are two new option packages: the FP6 Appearance Package for the Base V6 cars ($795), and the FP8 for Base GTs ($995). Both are essentially identical, comprising black painted mirror skull caps, black decklid spoiler, body-colored quarter window louvers, and black painted aluminum wheels (18" for the V6, 19" for the GT).
I've not pictures of the wheels so I don't know whether they are unique to these packages, but it sounds like they are. Neither package is available on Premiums, on convertibles, or in combination with certain other options (Perf Pkg on the V6; Brembo or Track pkgs on the GT).
EDIT: Just looked at the Build & Price tool. The V6's FP6 wheels look like the Pony Package wheels, painted black. The GT's FP8 wheels are the same 19" machined/painted wheels that were optional on the 2013 GT.
