I do not know much about wheels and/or tires. We have many posts on the forum (2005-09 era data will also be relivant to you) with regards to the various tires people have placed on S197 Mustangs.

If you want to keep a "Saleen look,"
Saleen Performance Parts offers two wheel designs for your 2014.
One: The 20x9" (Front) and 20x10" (Rear) "Secca" wheel. This wheel came to market around 2015; this is a Saleen designed wheel. It features thinner spokes than the Boss 328 wheel and has a flatter outer lip.
Two: The 19x9" (Front) and 19x10" (Rear) "Heritage Minilite" wheel. This wheel came to market in 2014; this is a Saleen designed wheel. It was OE on the Saleen/George Follmer Edition and very similar to the 2007 Saleen/Parnelli Jones wheel. This wheel is a current option on 2015-19 S302 White Labels and Yellow Labels.
Each wheel design "may" come in various colors/finishes.
*Silver painted
*Chrome
*Black Chrome
The 19" wheel may also come in a grey painted and black or gunmetal painted.
