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.

Good finish and quality, but without the performance struts and shocks, it`s just for the looks. Not much of a difference in handling with only the springs. And yes, you need a Panhard rod.

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!

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!


  • Unfortunately, these springs are not meant to be used on any convertibles. The spring rate is specifically for coupes. Sorry if the product page was a bit confusing!

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.

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!!

Hey there, I was wondering if anything needs to be done to the bump stops when you install these. I see the Eibachs come with newer shorter ones, do these come with new ones or no?


  • You can use these with your stock shocks/struts while re-using your factory bump stops or using a set of aftermarket bump stops. However, you may need to shave those bump stops down a little depending on your exact application.

    Received the springs in a box that was all beat up with holes in it. Took the springs out and it's just brown paper and the springs in the flimsy box. Springs are all scratched up and can see the metal under the blue. Probably just gonna return them and buy elsewhere. This isn't like AM at all.

    First glance opinion

    My previous mustang was on eibach sportlines which was really low . This car I installed the SR springs and it looks as just the front was lowered and not much wheel gap in rear was killed. Ride is way better than factory but that rear wheel gap isn't resting easy on my mind. Hopefully they settle soon so I can see the difference. Not completely disappointed but not exactly happy.

    SR Springs

    I've had these springs on my stang for almost a month and have no complaints. Running 18s with 1/2 inch gap on front wheel well and 1 inch gap in the rear. Still plenty of clearance but cleans up that 4x4 wheel well gap that came from the factory. I'd say performance wise they seem a little better than stock but not night and day, also worth noting that eibach camber bolts are more than sufficient for alignment. I am running the factory struts and shocks until one blows and the ride isn't any bouncier than it was with the stock springs. **Bottom line, if you are modding on a budget these springs are definitely worth the money. Grab some camber bolts and a panhard bar and your set!

I must say that I can not tell the difference between these springs and the last set of pro kits I bought. I would definitely recommend these to anyone. These springs were the perfect fit for my taste in the amount of drop and the ride quality.

    Bang for the buck

    Overall installation was easy, I did it in an evening. Spring compressor is the only out of the ordinary tool. Fairly cheap at most tool stores. Fitment was excellent. From wheel center line to fender lip 28.125 front and 28.5 rear, after two weeks of settling. Overall ride on normal roads is fine, but a bit stiff in the rear on larger wash boarded roads. Plastic speed bumps will break your back. Highly recommend adjustable camber plates or concentric strut camber bolts. Also recommend a watts link for more corning predictability. Well worth the money to get the better handling for my drift fun. Definite two thumbs up for this product.

    Looks Great But WOW Handles Improvement +

    So I recently put a new rim and tire package on my 07, and the lower profile tire made the stock gap look bigger, therefore time to lower. Had only wanted to lower it for the cosmetic reasons, and for the price I couldn't say no. Paired with GT-500 strut mounts and camber bolts, when I lowered the car I thought it looked sweet. Can't wait for it to settle. NOW, the fun part came 10 mins later when I hit the 'S' curve on ramp onto my local highway. Wow does the car stick like glue, the car hit the corneers aharder and tighter than ever before. Like it was on railroad tracks. So worth it, I was very impressed. You cannot beat this mod if you enjoy your car looking good and feeling good. The install was pretty easy, don't take it to a shop for 2-300$, have a buddy, some hand tools and a jack and stands? You can do it yourself in a few hours. If you have decent experience working with hand tools on your car and can follow the install guide on the purchase page for this product, it is a nice project. Really makes you feel like you earned it when you drop that 'Stang and rip it around town for a test run. The only reason I gave ride quality a 4 star is that the car is somewhat more bouncy/sensitive to bumps in the road, since the springs are stiffer you feel the road a little more. It was expected, but it is by no means bad, the overall set up feels great and I'm sure after a week I won't even notice it anymore. Overall LOVE it.

    Drastic improvement in handling, acceleration squat and brake dive eliminated, ride quality is retained due to the progressive spring rate, checked the alignment after a week of driving, alignment on the money, body lean eliminated, great product for under $170.00. Other techs at work checked out the quality and all said the same thing. Oh yea I work at a Chevy dealer and drive a real Pony Car.

    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.

    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!

    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.

    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. '
