APEX Wheels 2015-2022 Ford Mustang S550 18×10″ ET40 Anthracite EC-7 Wheel – Function Factory Performance

The EC-7 wheel includes details specifically implemented to enhance the Mustang owners’ track day and street performance experience. An optimized car setup begins with the right wheel and tire fitment, and without model-specific attention, maximum performance is compromised. These wheels were developed exclusively for S197 and S550 chassis and will work in either square or staggered applications. Most fitments are direct bolt-on solutions, however aggressive square fitments utilizing the 18×11” EC-7 wheels will require spacers on the front axle for proper inner strut clearance. This is not a compromised fitment, it is the only way to outfit an S197 or S550 chassis with the highly desirable true-rotatable 11” square fitment.
