Steeda 2015-2020 Ford Mustang Coupe Rear IRS Subframe Support Braces – Function Factory Performance

With the release of the new 2015-2020 Ford S550 Mustang, Steeda knew that addressing the IRS system would be a top priority. Being the first production Mustang with an IRS since the 03/04 Cobra’s, we knew there would be a great opportunity to capitalize on Ford’s new piece by giving it the Steeda advantage. As with any suspension system, deflection is an issue if it’s present. Anytime a piece is moving, twisting, or vibrating when it should be stationary is a major problem. One of the areas team Steeda wanted to focus on was the rear IRS subframe.
