    Review & Installation Video

    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 black powder coated 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 Black 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.

    With the Sr performance lowering springs will I need a adjustable panhard bar to keep the rear end centered?

    MatthewK

    • When lowering a car it would be recommended to get a adjustable pan hard bar to recenter the rear end yes!

    Does the upgrade make the drive really uncomfortable? Seems like it takes lots of shocks vibration in the car while driving.

    Aeroloco

    • The lowering springs are shorter than the factory springs and the have an increase spring ratio. The strut tower brace will stiffen up the chassis in the vehicle as well. These two components will sacrifice comfort for the increase in handling performance.

    Will this kit work on a convertible or is it strictly for a coupe.

    VincentD

    • The SR Performance Strut Tower Brace & Lowering Spring Kit is designed specifically for the coupe, and will not work on the convertible.

      Rob D

    Aside from getting the Lowering Springs would I need to get new control arms as well? A tire shop recommended it.

    BryanB

    • Hey Bryan, Not necessarily, generally the first thing you may need is a pan hard bar or caster camber plates because they would directly be effected by a drop. But the control arms are more for wheel hop and tightening the chassis for higher powered applications to stick to the earth.

    If you have an after market hood, and a bbk cold air intake, and you install the strut tower brace, will the hood close with no issues?

    Diego

    • The SR Performance Strut Tower Brace & Lowering Spring Kit will work with aftermarket hoods and cold air intakes. You will not have any clearance issues with the hood as long as it is not lower than the stock hood.

      Quality components

      Springs provide a great looking stance without sacrificing much ride comfort. The brace bar looks great under the hood. Together they’ll improve the handling and looks of your ride.

      Handling feels great

      Fills wheel well gap perfectly. Went well with AMR staggered wheels and Nitto tires. Handles like a beast now. Watch out for driveways and speed bumps though.

      SR Lowering kit with tower brace

      The kit fit without any problems. Works good. Even had a good ride with my old shocks. I haven't really got to push the cornering but the drop made the car look so much better.

      Great Combo

      I was doubting this set of springs. Thought they would not be that good for the price, but matched up with the Koni orange struts. What difference they make. I went this setup, with SR way bars, front and the rear shock tower brace.

      Tower and springs

      Great feel to handling, a must for your car. A little tricky to get to the front springs but totally worth it, when its all done. If going to do self installation would need alot of tools and time.

      Kit went on easily with just a few tools. Car looks great lowered. It did through the caster and camber out enough that I had to have the strut tower slotted.

      Easy

      It took me and my dad approximately an hour and half to install all of the springs and brace. We found that you do not need to remove the brake rotor or caliber. We did this project on jack stand with absolutely no problems. Car handles great and looks alot better. Would highly recommend

      Amazing product, great handling!

      I origanally bought this product for looks, because ya know, who doesn't love their stang to be nice and low to the ground. But, once I installed, the handling of my car felt like a whole new car! There is very minimal body roll, no nose dive when braking hard, and the front end barely raises when I floor it. Overall the car feels more grounded can grab corners very well. Very pleased with these lowering springs and strut tower brace!
