The Mustang features good rigidity from the factory, but sports cars can always benefit from more.
Steeda says their S550 Rear IRS Subframe Support Braces can help with that. Connecting in three (3) strategic points & triangulating the points help eliminate deflection from side to side & front to back. It also offers rigidity – helping the Mustang’s subframe to become more planted in place.
Their video gives a great overview of what is taking place & how the IRS Subframe braces can be integrated to give your S550 added support.
