    SR Performance Lowering Springs. Installing a set of SR Performance Progressive Rate Springs will lower your Mustang's center of gravity, which will reduce squat during acceleration, body roll in the corners, and excessive nose-dive under hard braking. These springs not only improve handling, but they also improve the appearance of your Pony by lowering the ride height approximately 1.5" to eliminate that ugly "4x4" tire to fender gap, for a more aggressive street stance.

    SR Performance Strut Tower Brace. Eliminate unwanted chassis flex and body roll in your S197 Mustang with a SR Performance Strut Tower Brace for improved handling. This Strut Tower Brace is made from super strong, aircraft-grade 4130 chromoly alloy steel to keep your front end from flexing under the torque of your motor and it is completed in an attractive bright chrome finish for durability, corrosion resistance and impressive under hood styling.

    Recommended Upgrade. Anytime you lower your Mustang, your rear axle gets moved out of alignment. Adding an Adjustable Panhard Bar will not only center your rear axle, but offers great traction during straight-line acceleration as well as superior strength over the factory panhard bar.

    Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your factory size wheels and tires, as well as AmericanMuscle's pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.Application. This SR Performance Chrome Strut Tower Brace & Lowering Spring Kit is designed for use on the 2005 to 2014 V6, GT and Bullitt Mustang Coupes. Does not fit convertible models.

    Springs Technical Note. SR Performance Springs will only fit 2011 to 2014 GT and V6 Coupes when used in combination with Ford Racing M-18183-C upper strut mounts and M-18000-A dampers (sold separately).

    Strut Tower Brace Technical Note. Some 2007-2009 V6 Mustangs may require minor modifications to assure proper clearance of the factory coil pack boots. Will not clear BOSS 302 Intake Manifold or Edelbrock E-Force Supercharger.
