S197 seats, particularly those in the GT500, offer a nice balance of comfort and lateral support. Let’s face it—they are much nicer than the seats offered in many of their predecessors. One sticky point of these seats, however, is the non-adjustable headrests. To the rescue comes TMI with its four-way-adjustable, tilting headrests for ’05-and-up ’Stangs. They are available in colors and materials to match the stock seating.
