    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

    Monkerfish

    • 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!

    What is the correct orientation of the rear coils? They are not marked bottom or top and did not come with instructions. I installed them with the tighter coils on bottom but was not sure if that was correct. I could not find a straight answer on any message board.

    • 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?

    Imjackswastedlife

    • 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!

    Don't know a lot about this stuff... help! I have a 2013 Mustang V6 and I added some 18x9 gt500 wheels from AM. But the gap was large so I wanted to lower the car. If I buy these will I need to but any additional components or are these a bolt-n-go set of lowering springs?

    GTSHELBY

    • Hi Jmp, These should no problem going on. The only thing is that you might want to invest in an adjustable PANHARD (apx $100 give or take). You might throw your rear end off a little.As for chamber.I only needed the bolts for mine($30) This are really nice springs and you should feel a slight ride difference (more aggressive) which will make your experience more fun when driving.Well worth the money..ENJOY DUDE!!

      They look good but are too bouncy

      I really like the way these make my car look. 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. I can’t go over speed bumps because if I do the car bounces like 3 times. But I guess for the price is not so bad

      Great Springs for the Price

      First time buying/using SR springs and I am impressed, the stance is perfect and the ride quality is way better than stock imo. I did purchase Eibach Pro-Damper Shocks/Struts and Caster Camber Plates with the springs so I am fairly certain my ride quality has alot to do with those items. If you are just buying the springs the ride will probably be rough, however if you are strictly lowering just for the look these are the perfect springs for that. Thank You American Muscle!

      YOU GET WHAT YOU PAY FOR!!!

      I have had these springs since I got my car in 2014 and I just recently put new wheels and tires in my car and I had some rubbing isues with the rear tires so I look at my rear springs and they are completely compressed! So now I’m buying some good Steeda springs instead or these cheap ones... I guess you get what you pay for. And I have never had problems with America muscle until I had this issue. I told them what was going on with my springs and sent them pictures of the springs completely compressed and they where no help at all. never responded.

      Great look

      The rear took me 5 min to install, the front is what takes time, no need for spring compressors if you have a jack, just remove the rack and pinion from the a arm to make it easy and safe, and when putting the new spring on strut, set it on, put strut mount on, slight compress and tighten top up, and reinstall. Takes time but very worth the look.

      Sr lowering springs

      Was very undecisive of which lowering springs will be best for my fit. I went ahead and pulled the trigger with these. Couldn't be any more happier, with 305 35-19 in the back really gave the stance that I wanted without rubbing. Not only does it look alot better but performs like it's supposed to. Really satisfied
