Review & Installation Video

Hey, I'm Justin with, 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!

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.

Fitment Hello, I am unsure if the springs will work with an '07 convertible, the exceptions seem to be '11 and up 'verts. Any advice would be great, thanks!

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!

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?


  • 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!!

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.

    I took a chance

    Before I purchased these springs I searched the internet and all some of the bigger mustang forums to find some feedback with no luck. A few people inquired about them only to get feedback such as "go with Eibach or H&R" I compared the specs of these springs to the Ford Racing K springs and found them to be real similar so I figured "what the heck I'll give them a try". The springs came in a nice powdercoat blue, installation was a breeze and the ride quality and handling is pretty much that of any other name brand springs i've had in the past. The money I saved on these springs paid for my strut tower brace and Eibach pro elignment camber bolts. If you are budget minded i highly recommend these springs. Thank you AM for getting these springs to us for such an affordable price and once again a speedy delivery.

    WORTH IT!!!

    I bought this item with confidence in SR Performance items in the past. What can I say just out of the box a extremely noticeable difference in size of the springs. Installation: Installation was a breeze with no issues at all. It literally took me an hour to do with alignment and test drive. The benefits of being a mechanic and having a shop for a lift to use is the better part. Alignment: The almost best part about this than looking at the great look is the alignment. I did purchase camber bolts from my local parts store because AM didn't have them in stock at the time of purchase. But those was not necessary. I had a previous alignment print out from my other alignments I perform about every other oil change and there was a change in caster only by .2 degrees on driver side and camber was not affected. That is nothing since cars are generally off from factory to compensate road curvature. Finally Road Test: Road test was great, A great increase in handling once took it down the road and over a bunch of bumps to set in the new springs. Ride is not to soft just a little stiffer than stock, which is perfect because I like to feel the road. As far as turning goes, had no body roll. I put a strut tower brace on my car previous of installing springs and thought that was enough. Well was proven wrong once I put these on. Overall: Everything is great installation was easy. Ride is perfect and couldn't be happier. It lowered my car little short of 1.5 inches than stated to about 1 1/4 which still looks fine to me. I recommend these to anyone trying to save a little bit of money but get the same quality and look from those more expensive springs. Thanks AM for another great product.

    SR Springs, affordable and awesome

    I installed these in about 3.5 hrs with a two post lift, (make sure you either have some mini ramps or a jack) and they lowered it great. Now I'm just waiting for the springs to settle and I'll add a picture of the difference (look for a white and black hockey striped 'stang) The quality of my daily ride was increased and with a set of 245/40/18 on the front and 255/40/18 on the rear the stance is killer. I'll post back in once I have let these settle in a few months, but so far... great buy!

    totally satisfied

    I purchased these springs a few days after they became available on AM. I was a little skeptical at first due to the price and lack of information about these on the web, but took my chances. I'm glad I did. For a daily driver they are not too stiff by any means, but made a huge difference in handling. I had Eibach springs on my '06 Charger and find them to be up to par. The stance is perfect in my eyes. It left the front slightly lower than the back which is the way I like it. '

    What a great improvement for half a day's work and less than $200!

    I bought these springs over President's day, and got a deal I couldn't pass up... I have a 2012 Premium V6 Performance Package Mustang, so it already had upgraded suspension.. but I wanted it a little lower. I was able to re-use my stock spring isolators, and used the factory shocks/struts too .. installation does require some specialty tools - spring compressor, and a good assortment of large metric wrenches and sockets - and don't forget a breaker bar for some of those stubborn nuts/bolts. The hardest part was getting the nut off the top of the strut... the front two springs took me nearly 3 hours to do, and the rears took me about an 1.5 hours total.. including removal of wheels, jacking the car up and down, putting tools away, etc. no air tools were used .. and would have made the job faster, for sure. I am very happy with the resulting ride height (it's been a week, and about 300 miles since I installed them) ... ride is not a lot stiffer/firmer than the stock Performance Package ride was, but it is just a little bit... feels good though. Squat at launch is reduced, and nose dive on braking is also reduced. I didn't have to get a different panhard bar... and didn't do any camber plates or bolts - I will be taking it in for an alignment soon, now that it should have settled a bit since I installed the springs.

    Huge Handling/Appearance Upgrade!

    Lowering springs are an absolute MUST for any newer Mustang. The wheel gap is hideous and the handling seems loose. These springs fix all of those issues. Installation was easy with the right tools. You will need a spring loader to compress the springs for the front. The rear springs took 10 minutes start to finish. The front really takes all of your time. A few things to know: 1. It will make your ride much harder. You will feel every bump you hit on the road. 2. There is a much higher danger of scraping on large bumps, steep driveways, etc. Overall, excellent product and I highly recommend. The appearance and performance upgrade is well worth it. I only wish it were slightly lower

    The springs went on without any difficulties. However, I did not get the drop I was expecting. They advertised as a 1.5 inch drop front and rear.....The front did come down approximately 1 inch. The rear came down about 3/4 inch. I am dissappointed about did increase my braking capacity quite a bit and no "nose dive". I really wanted the drop.....I run 16" wheels on the car.....

    "Bang for your buck" is an understatement

    These spring are as good as any other and the price is obviously a steal. Did it myself with jack stands and an impact wrench. (Not to mention a casted right arm). Watched a few detailed YouTube videos for some tricks of the trade and rocked it out in about 4 hours.

    SR 1.5 lowering springs

    picked these up on the Black Friday special, couldn't pass them up! installation was straight forward. I did it myself, after a few call to local shops that wanted 330 installation fees....bleh, no thanks. took me about 4 hours to do front and rear, exercising extreme caution. the springs are under great pressure. when I took the front strut/spring assembly out, I used a jack under the lower a arm, applied some pressure, and then attached the spring compressors, tightened them up "some" and lowered the jack. too easy. rears were easy to do. pay attention to abs sensor and brake lines when removing brake assembly. it's a little unnerving when you lower your axle. I didn't disconnect the driveline, so pay particular attention to how far you lower your axle. first side was a little hard, still has even pressure on each spring. second side is easy. so, I have about 140 miles on them and so far, so good. great bang for your buck and my 2010 GT looks sick. thanks AM!

    Great improvement to 2014 GT Track Pack

    I got a set of SR springs during the Black Friday sale because they were a great price. I was a bit nervous that the estimated 1.5" drop would be too much for my taste. Finally installed these in April 2014 along with Koni shocks/struts, GT500 mounts, and ford racing jounce bumpers. The drop on my GT Track Pack is perfect after I got the setup installed. With the Koni STR.T dampers, the ride not harsh at all and is very similar to the OEM track pack on the highway or cruising. But brake dive is vastly reduced, roll is greatly reduced, and the car just feels locked down. The floaty feel is gone, and turn in seems much more precise. This is how I would have liked the car to feel from the factory. Highly recommend these springs in combination with an upgraded set of dampers.
