    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.

    Ask a Question

    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.

    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.

      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!

      Awesome upgrade

      I've owned my '05 Mustang GT since new. It only has 28,875 miles on it and this is the first significant modification I've made. What a difference! The springs lowered the car almost 2 inches (advertised as 1 1/2") and their "progressive" rate soaks up small bumps (no more hopping), so the car rides smoother. But, when pushed you get into the stiffer part and the car handles like it's on rails. The strut tower brace increases steering response so much it actually feels like a different car. Best money I've ever spent.

      SR Performance Strut Tower Brace & Lowering Spring Kit - Black (05-14 GT, V6)

      This was one of my first buys for my 06 gt soon to be followed up my some major mods and WOW. The Ride and handling on the car is sutch a big differance you will notice it right away, not only from a stance point in the way the car sits( Looks Good with Stock Rims with that 1.5" drop) but also in how it goes through the corners( Nice tight front end drives into corners no dipping). I purchased the recommended pan hard bar from S.R.P. for the adjustment in the back end. A recommended alignment is also required( Better For longevity of tires). Took About 3.5 Hours i panted the calapers and touched up on underneath paint, great look with the deep Blue springs fits nice with factors shocks and struts very easy with basic hand tools. The Black finish on the strut tower brace gives a sleek, clean look for under the hood( i wasnt looking for bling, going for the sleeper car)

      SR springs and strut brace

      very pleased with this product. I put the SR springs and the SR strut brace on at the same time and it felt like a completely different car, also giving it a great stance. lowers the front perfectly just wish it lowered the rear about a quarter more of an inch then it does but that's just my personal opinion. overall both great products especially for the $$

      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.

      Noticeable improvement

      Really changes how you drive your car. The lowering springs and strut tower brace really tighten up the steering and gives you a more responsive feel. No more nose dives while braking and not near as much body roll. And also seems to give you less understeer and will give you a little more confidence when your coming into a corner hot. This is a great first modification to your car!

      Excellent item

      I like it because it looks more stout than others I've seen that only lock onto 2 bolts, this one is sturdy and takes less than 15 minutes to install. Went on easy and looks fantastic. you can feel the stiffness when you take it on turns. and even straightaways you can a tell a difference. i have a 2014 v6

      much improvement

      It took about 3 hours to install. It took a little longer because some of my bolts were rusted, and I didn't want to snap or strip any of them. The acceleration and braking improved, the stance even on stock rims looks good. The car doesn't want to roll in corners as much. I'm sure the brace helped some also. I was expecting a rough ride after, but even my wife said there wasn't much of a change.
