.Justin: At right around $140 the SR Performance Lowering Springs that we have here are gonna be the most affordable way to lower that 2005 to 2014 Mustang compared to your other spring options currently here at AM. Now in addition to being the most budget friendly set of springs they will also lower your car a total of one and a half inches on all four corners which is gonna give you a nice even drop or stance that still maintains a little bit of that factory nose down rake. Spring installs, listen, guys, they are pretty straightforward with the S197 but because they will require the use of specialty tools like a spring compressor the site is gonna kick this one up to a soft three out of three wrenches on the old difficulty meter. Maybe a few hours to complete from start to finish as we'll show you guys later in the video.But with all that said, let's dive right into some of the finer details of the SR Performance Lowering Springs. And first and foremost, that drop, right. The number one factor when purchasing lowering springs and you're gonna be looking at one and a half inches here on all four corners with these springs installed. Now if you've been shopping around a little bit you'll probably notice that's a drop a lot of manufacturers tend to go with for the S197 and there's a big reason for that. It's low enough to make a pretty dramatic impact in styling, eliminating that ugly factory wheel gap but at the same time, it's not gonna cause any rubbing, car isn't gonna be totally slammed to the ground and therefore scraping on every speed bump or low driveway in town. Now this is a great time to remind you guys to check out the numerous customer submitted images on the product page if you haven't done so already because it's a great way to get a feel for how your own car might sit once the springs have been installed and while you're there, feel free to read up on the numerous five star customer reviews.Now the SR Springs here do also feature a progressive spring rate which is another popular feature in the aftermarket spring category and that just simply means they're gonna progressively firm up the harder they are compressed. Now your specific initial rates here for the SR options include a 230 pound front spring along with a set of 200 pound rear springs which tends to be pretty much average in the category for a nonlinear spring in the aftermarket S197 options.Now I do get a lot of questions about installing the SR Springs or any spring for that matter on your factory dampers and what I will say is, guys, sure, if money is a little tight and your factory stuff isn't terribly beat then you can certainly do so. However, I will always tell you that upgrading to a different damper that is better designed to handle the lower ride height, firmer spring rate, things like that is only gonna result in a better experience overall including just better ride quality, performance and so on. So just something to keep in mind here, guys, when shopping aftermarket springs and that's something to consider if your budget will allow for it.But now we wanna show you just what it takes to get the SR Performance Lowering Springs installed on your S197 at home and to do so here's that detail walkthrough we promised you earlier along with a quick tool breakdown.Man: The tools used for this install are a half inch impact gun, a three-eighths impact gun, a quarter inch impact gun, an 18 millimeter socket, a 15 millimeter swiveling impact socket, a 13 millimeter socket, 10 millimeter socket, 21 millimeter ratcheting wrench, 10 millimeter box end wrench and a dead blow hammer.To get started on this install you're gonna wanna support your vehicle from the designated lift points and you're gonna wanna pull your front wheel off. Once you've got that going you can start removing your strut assembly. So the first step you're gonna wanna take after you remove your wheel is to pull your caliper and rotor assemblies off the car and get them out of the way so that you can get to work.All right, you're gonna need a 15 millimeter socket. I'm using a half inch air gun and a swivel socket but this can be done with a ratchet and socket set. With the caliper unbolted you can use just a regular bungee cord and hook it into your caliper and tie it off to the sub frame so that it stays out of your way and doesn't fall loose. Next I'm gonna use a 10 millimeter socket to unbolt the brake line retaining clip and then use a clip panel tool to remove the Christmas tree clip that hold the ABS and brake lines to the strut assembly. Using a clip tool I'm gonna remove the clip. Next I'm gonna use an 18 millimeter socket to remove the upper part of the sway bar end link from the strut assembly. And now using the same 18 millimeter socket I'm gonna remove the 2 lower strut bolts that hold the strut to the hub assembly. Final step to removing your strut assembly is going to be to remove the four nuts up at the top inside the engine bay and once you remove those, your strut assembly should come right out.Now that you've got the strut out of the car you're gonna have to swap over your spring and your top mount over to your new strut. This can be accomplished with a spring compressor. I'm using a wall mounted unit but you can also use a handheld unit or, if you're not comfortable with that, take it to a local shop and have them swap out your strut and spring assemblies to your new one. That is just about perfect right there.Now that you've got your spring compressed you wanna remove the top nut for the strut assembly. I'm using a 21 millimeter ratchet wrench and a 10 millimeter box end wrench to hold everything while I unscrew the nut. Now that we have the strut assembly taken apart we can decompress the spring and move the top mount over to our new spring and reassemble the strut. Now we're just gonna pop the top mount off of the spring and transfer it over to our new one. Make sure to line up the stop mark on the spring stop so that the spring doesn't move when you put it back in the vehicle.Now with our new spring installed on our strut we can put the whole assembly back into the vehicle in the reverse order of removal. And we'll throw the caliper back on.So because this is a solid rear axle vehicle we're gonna actually accomplish removing both springs at the same time by lowering down the rear differential. We're gonna do this by unbolting the sway bar from the body and we're also going to unbolt the lower shocks. Once we do that, we can lower our differential down, pull both springs out at the same time and put in our new ones. So I'm gonna use a 15 millimeter socket and impact gun to remove the sway bar end link from the body.With the links unbolted you can swing the sway bar down out of your way. Before I can unbolt the shocks I have to support my rear axle so that my springs don't unload while I try to unbolt everything.Once again, using a 15 millimeter socket I'm gonna unbolt the lower shock bolt from the diff. Now using the screw handle on the pole jack I can slowly lower down the rear differential which will unload the springs and allow me to remove them from the car. Make sure to retain the isolators on the stock diff. you're gonna need them for your new springs. With our old springs out of the car, we can throw our new ones in and put everything back together.With my new springs installed up into the pockets I can raise my rear differential back up, reconnect my sway bar and my shocks and this is completed.Once all four corners are wrapped up, you can throw your wheels back on, take your car to get an alignment and that's gonna wrap up this review and install for the SR Performance Lowering Springs on these '05 to '14 Mustangs.

Highly Noticeable Improvement
The car handles MUCH better with these springs (even with the stock shocks and struts), and it also looks much better. Would buy again.Helpful (0)

I am very happy with the new stance of my stang! shipping took forever but it was probably due to Christmas and new year. Took like 2 weeks, paired with new struts. Easy install with basic hand tools. Took all weekend, but that's probably because of age and rust. Hopefully you don't have that issue.Helpful (0)

Sr performance springs
They do drop your mustang i can tell a difference when im standing at the front with the hood open its alot lower. But there is a lil bit of wheel gap i have the 20 inch am bullitt wheels on my car. Rides nice alot firmer. Feels like the car hugs the road better. Wanted it a little lower but it is lowered enough.Helpful (0)
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
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.
tighter coils go on top. here is a video to look at. http://www.youtube.com/watch?v=QZDB3EpqQT0
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!
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!
The SR Performance Lowering Springs will not require an upgraded panhard bar. However,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.
The SR Performance Lowering Springs will not require caster camber plates for installation but makes a nice add-on especially if you are looking to dial in angles of the suspension for optimal use. We recommend any caster camber plates that are applicable for the stock struts as some are specific to manufactures struts/coilovers.
I got a 2013 with performance package. I honestly just wanted it for looks but was super surprised at his much better the car handles. No more brake dive, launches are quicker, and cornering is sharper.
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!!
The SR Performance Lowering Springs may take a week or so of driving to fully settle to the correct ride height. If your springs have not leveled out after a week of driving, please contact our Customer Service department so that we may best assist you with this.
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.
They will 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).
