Description
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 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 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.

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!

laverdajota Year: 2007 Model: GT

  • I don't think these will work on a vert. You'll need springs specific to the vert because the vert weighs more and has extra bracing to stiffen the chassis. I'm not sure if it's a fitment issue or a safety issue. I wouldn't take a chance if I were you.

Will I need new caster camber plates with these springs?

Jhicks20 Year: 2009 Model: V6

  • I just installed mine and did not need new CC plates. I did pick up CC bolts to adjust the camber a bit but no, you shouldn't need new plates.

    Great ride and handling

    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.

    Perfect fit, perfect drop

    Easy install, about an hour. Ride quality is great, just a tad stiffer than stock. With my 19" premium wheels the drop is perfect. For the price and quality you can't beat these springs. My brother runs eibach sportline on his '13 no difference in ride quality but it is a tad lower and I mean a tad. Do not let the price scare you. Get em..

    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.

    Awesome

    Just installed these, and let me just say that they far exeded my expectations they ride almost the same as the factory springs, and make the car look amazing. I had an 06GT that was lowered with springs from another company and these outperform them by miles. Anyone who gets these will not be disappointed.. Thanks AM.

    just as advertised

    After see 100+ reviews with good feed back I had to try them. I've always favored the eibach springs but these are a great alternative. My car rides and handles great, the body roll and nose dive during braking is gone. Gave my car a good drop very close to the 1.5. Don't let the price sway you, they are a quality set of springs.

    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!
