Review & Installation Video

Improves Handling Performance. Steeda's street competition sport lowering springs may only lower your ride height 0.2 inches in the front and 0.8 inches in the rear, but this little change will greatly improve your Boss 302 Mustang's overall weight distribution for arguably the best handling Mustang ever produced.

Progressive Rate. Using a substantially increased progressive spring rate these Steeda competition sport lowering springs will greatly reduce squat during acceleration, body roll in the corners, and excessive nose-dive under hard braking.

Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your stock 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 set of four Steeda Sport Competition Springs are specifically designed for use on the 2012 to 2014 BOSS 302 Ford Mustang.

Do I need an adjustable panhard bar for a 2012 Boss 302? Can I install these springs without having to use an adjustable panhard bar on my 2012 Boss?


  • It is highly recommended that you run one since the rear of these cars shift when lowered.

Answer This Question

Is there any reason these springs wouldn't work on an 11-14 GT?


  • Hi, These spring were designed for use on the 2012 to 2014 BOSS 302 to improve the overall weight distribution, using this set of springs on a GT will cause a rough ride because the spring rate is different for a GT vs a Boss 302.

    The Steeda Boss lowering springs worked perfect!

    I have a 2013 Performance White Boss 302 and these springs were perfect for what I wanted They lowered the Boss just right and no sacrifice to the ride. I still clear speed bumps and it handles better then ever!!
