    Review & Installation Video

    Hey, I'm Justin with AmericanMuscle.com, and this is our handling pack Bolt-On Build-Up for all 2011 and Newer Mustang GTs. These new Coyote Mustangs are a far cry from previous generations in many ways, but specifically in regards to both performance and handling. In fact, several reputable automobile publications have tested these cars to be on-pace with other European and Japanese sports cars nearly twice the price of the Mustang. Not too shabby for a live, actual, car huh? So why mess with the handling then? Well, because we can make it better, and because Ford already gave us such a great platform to start with, it shouldn't take much to get our car to the next level. So with that said, let's check out the three parts in our handling pack. First up, we installed Eibach's Anti-Roll Sway Bar Kit. Now again, from the factory, our GT came with a pretty decent setup, but was more of a balance of comfort and handling performance. This kit from Eibach upgrades our factory 24mm rear bar to a larger 25mm bar, and it also upgrades the front 34.5mm bar to a 3-way adjustable 36mm bar. The adjustability of that front bar is going to really allow the driver to dial in their optimal settings, to better fit their driving style. Now finally, these sway bars are going to be vital in reducing any excess body roll the car possesses in stock form, which will really give the driver much more confidence on the road, and in turns. To further help strengthen our chassis we installed this SR Performance Black Strut Tower Brace. Now we enjoy using this part in a number of our builds for a number of reasons. It's easy to install, it looks great under the hood, and it's going to further help reduce our suspension flex. It's a win-win mod that just so happens to be easy on your wallet. Finally, we throw on a set of SR Performance Lowering Springs which, as you might have guessed, lowered our Coyote an inch and a half in all four corners. Now the lower center of gravity and stiffer spring rates, will no doubt improve our handling, and when paired with Eibach's Anti-Roll Sway-Bar kit, should make for a firmer, sportier ride without being uncomfortable or offensive. Now as you can see, lowering our car certainly improved our stance as well, by getting rid of that ugly wheel gap. We kept our build simple, by using only three basic parts that should take our already great handling Coyote to the next level. With that said, let's get our GT out of the shop, and see if we succeeded. Alright, so we're out on the road in our 2011 GT handling pack installed of course, and already the car feels great. Feels much firmer than before but, like I said, not in an offensive way, it's not uncomfortable, it just feels more sporty now. Things feel a lot tighter, the car overall feels more solid, just cruising down the road. Even just a couple short jerks of the wheel here, I mean, lane changes at high speeds now are definitely going to be improved but, let's put these things to the test, we've got a hard left-hander coming up, let's see how she does. A little bit of brake-dive coming into the turn. Point it, stomp on it, and it goes. Man, the body rolls definitely been reduced thanks to those Eibach Sway-Bars, front end feels a little tighter as well thanks to that SR Performance Strut Tower Brace, and again, the springs just make the car feel more nimble. I mean, let's face it, it's a big car, big-right hand car coming up. Boom, no problem whatsoever. And as I was saying, it's a big car, man, it's a heavy car, but it doesn't feel like it's lumbering through the turns anymore. It actually feels a lot lighter, and a lot more nimble than it probably actually is. Overall, I'd say job well done with us here in our handling pack. So that wraps it up. Be sure to check out some of our other Bolt-On Build-Ups for the 2011 and newer GT, where we make our car look a little better, and really crank up the performance.

    Improves Handling. 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. SR Performance Springs are great for daily driving, street, and even occasional track use.

    Aggressive Stance. Not only does a set of SR Performance Springs improve the handling performance of your Mustang, but they also improve its overall appearance by lowering the ride height approximately 1.5" to eliminate that ugly "4x4" tire to fender gap, for a more aggressive street stance.

    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 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 SR Performance Lowering Springs are designed for use on the 2005 to 2010 GT & V6 Mustangs Coupes. They will also fit 2011 and newer GT & V6 Coupes when used in combination with Ford Racing M-18183-C upper strut mounts and M-18000-A dampers (sold separately). Does not fit convertible models.

    are these spring meant to be used with oem shocks and struts or aftermarket? if aftermarket which shocks/struts compliment best? I am looking to lower my car and want a stiff ride, not bouncy..thanks

    • They're definitely going to work for you on stock shocks & struts. Because the drop on these springs isn't super aggressive, you can get away with it. I would definitely recommend doing the shocks & struts down the road in order to maintain factory-like ride quality, but it's not a necessity. These already have great ride quality, so try the springs alone and see how you feel!

    I would like to know if these springs will work with the 2011 stock parts or do i need to order something else to go along with it

    • Unfortunately, when utilizing this kit on a 2011 or newer GT or V6 mustang it is required to also have the upper strut mount kit M-18183-C as well as the dampers m-18000-a, which do no come with the kit and have to be purchased separately. https://www.americanmuscle.com/frpp-gt500-strutmount-0512.html https://www.americanmuscle.com/frpp-shockstrut-0514gtv6.html

    How do these compare to the FRPP "N" Springs I have a 2007 V6. Aside from being cheaper, how do these compare technically to the FRPP "N" Springs for the V6? I am aware of the .25" drop difference. I'll be using stock shocks. How does the quality compare. I have some other SR products but I am nervous about buying something they made that is mission critical like a set of springs. Do they have any kind of warranty?

    • The quality of these springs are great! They're comparable to any other aftermarket springs on the market and are set up with proper spring rates for the 05-13 chassis. You can use them on stock shocks/struts without any issues, and change them out down the road if you really feel it's necessary. However, the ride quality on these springs are really good, as well. We've installed them on 2 of our own S197's and reduced nosedive under heavy braking, got a little bit of better handling with the lower center of gravity and the stance is much better. Wheel gap is no longer an issue! SR Performance, like many manufacturers, stands behind their products. If you have any issues with them, just give AM a call and we'll get it taken care of! Besides the drop difference, they're going to be very similar to other aftermarket springs, because most are engineered for a moderate drop that's a little more responsive. Hope this helps!

      I bought the SR lowering springs to complete my kit for my 2014 V6 Mustang. The installation was a breezed thanks to the instructional videos provided by American Muscle.

      Yesterday I had these SR Performance springs, along with the KONI STR front struts, KONI rear shocks, Whiteline adjustable panhard bar, along with the camber bolts and the car looks and handles amazing. You get quicker launch and makes driving on winding roads fun. I will post a picture later.

      Night and day difference

      I coupled my SR performance lowering springs along with the SR shock/strut kit and it was on of the best decisions I have ever made. My car feels amazing, it’s handles turns and windy roads with ease. I couldn’t be happier. Especially for the price. Install wasn’t too bad, I did go and rent a spring compressor from Orielly auto parts. So if you don’t have a spring compressor I recommend renting one most places issue a full refund if you return it within a certain time frame. This was my first time ever doing something like this and the install took about 5-6 hours.

      Solid Choice

      As far as "budget" springs go, these are great. Ride quality wasn't hurt terribly and the lower center really helps in the corners. I did the install myself on a friend's lift. If you're not comfortable, get an experienced set of hands. Then get an alignment. They do take a few months to really settle in to what your ride height will be, so don't worry if it's not as low as you'd like right off the bat.

      Good low cost mod! Looks great!

      Very pleased with the stance on my 2014 GT/CS convertible. If you're not a gear head, don't even think about installing these without help. Only issue is that these will bottom out on big speed bumps unless you are creeping. That's the only reason I gave these four stars instead of 5 stars. I'm happy and it didnt break the bank.

      Great but do still leave a small gap on rear tires

      They were pretty easy to install. I feel like the hardest part of the entire process was unbolting everything rather than exchanging the springs themselves. I loved how the front springs left no gap at all. However, the rear springs did leave a small gap still but they still made a major difference compared to how high my car was before.

      No spring compresser needed

      When you do this make sure you have a friend to help. Total time it took us was 2 hours. If you need help I would recommend just watching LMR (late modle restoration) My car got a lot lower and the ride got a lot stiffer which is great for when you floor the gas. You have a faster acceleration and looks a lot better

I have to say they seem like they are pretty good quality and great paint finish but they are not as I imagined them being these feel more bouncy than the stock ones I had so they fall short there.
