Improves Handling. Installing a set of SR Performance Standard 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. When installing new springs you should also replace your old worn out rubber Spring Isolators with a new set of Polyurethane Spring Isolators, see drop down option above.

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 1979 to 2004 V8 Ford Mustang Coupes, including the LX 5.0, GT, Bullitt, Mach 1, and 1993-1998 SVT Cobra models. Does not fit 1999-2004 IRS-equipped SVT Cobras.

Phenomenal for the price

Dropped my 89 gt exactly 1.5 inches on the dot. The ride isn't as bad as made out to be and it really looks great. I definitely recommend these

I’m Justin from, and this is our handling bolt-on build-up for all ’99-‘04 Mustang GTs. The goal with this build is pretty simple, we’re looking to take some basic suspension components, install them on our 2000 GT here, in an effort to make it handle a lot better than it does now in stock form. Now, individually, installed each of these parts will make a slight difference in your car’s handling. However, when installed together, like we’re going to do today, they should make a substantial difference in our cars’ handling and should make our GT handle like it’s on rails. First up on the list to install is this black strut tower brace that we have laid into place, just so we can see how it’s going to sit. Now this is a very popular first step for making your car handle a little bit better, and it’s going to be pretty easy on your wallet as well. Now basically, this is going to firm up the front end and reduce chassis flex and body roll. I have to admit, that black powder coated finish is going to look pretty cool under the hood as well. The next mod we’re going to go with for our handling pack is a set of these QA1 Caster Camber Plates. These are going to be very valuable for getting our GT’s alignment back in spec after we lower the car. A properly set up alignment will not only help your cars handling, but it’s also going to save your tires from premature wear. Speaking of lowering the car, what suspension build would be complete without a set of lowering springs. We’re going to install a set of these SR Performance lowering springs which will lower our GT roughly an inch and a half or so on all four corners. Not only will this help our ride handle a lot better thanks to that lower center of gravity, but it’s also going to help our appearance as well by getting rid of that ugly wheel gap. Last and certainly not least are these front and rear sway bars from Eibach, sway bars are one of the biggest factors to reduce body roll and are a great tool for fine tuning your suspension. From the factory most Mustangs have the tendency to plow or push through turns, this is referred to as under steer. By installing a larger rear sway bar and tweaking the front, you’re actually going to eliminate that under steer and introduce a little bit of over steer, which means the rear of the car is going to come through the turns much quicker, and actually make the car a little bit more fun to drive. So those are the parts we have in store for our GT here today, now let’s get everything installed so I can get our GT out of the ‘shop and onto the streets, and see the difference this handling pack makes. Alright so I just got our 2000 GT out of the ‘shop and onto the street here, and it took me all of 5 seconds the realize what a difference this handling pack makes to our ride. Gone is the kind of floaty, disconnected feeling that our Mustang used to have, and it actually now feels like a sports car, it feels like it should - much more firm, much more planted, even going straight, obviously through the turns it’s a lot better as well. The car just feels like it wants to respond to your actions a lot more, making it feel like you’re actually part of the car, which is great, and you can just slide turn to turn, going straight here like I said, the car just reacts well to whatever you want to do to it. We have a nice right hander coming up, let’s see how the car reacts with our new mods installed. All right, so much better, the car is just so firm and so planted going through those turns, that can definitely be attributed to those sway bars working with that SR Performance strut tower brace to really reduce our body roll and our chassis flex. I got a nice left hander coming up as well. Oh yeah, you can totally come into a turn now with much more speed and much more confidence going through the turns. The nice thing about the springs too, obviously they lower the car making it look a lot better and handle a lot better, but it’s also better for acceleration and our braking. The car doesn’t want to nose down now when you’re hard on the brakes coming into a turn, making it feel a lot more solid. Those QA1 Caster Camber plates are probably not going to make the biggest difference in your everyday drive however it was able to get our car back into spec after we lowered it about an inch and a half, just so we didn’t chew up our tires and made for a lot better handling. So there you have it, this handling pack really made a world of difference on our GT and really made our car a lot more fun to drive. Be sure to check out some of our other ’99-’04 bolt-on build ups where we work on our appearance, help get our GT off the line, and give it some more power.

caster camber plater does it requires to chage caster plates? and the struts?


  • It does not require CC plates; however, caster camber plates are highly recommended to bring your alignment back to the proper specs on any drop over 1" to prevent uneven and premature wear on your tires! Shocks and struts are also not required but will help you obtain the best handling from your Mustang!

will these fit an 01 v6 mustang?


  • These springs will fit a V6, but the spring rates were specifically designed for the extra weight of the V8. While you can install these on a V6 no problem, you're not going to get as big of a drop as you will on a V8.

    Awesome Product for the Budget Builder!!

    Installed these springs in a full day by myself in my driveway with basic hand tools, a good jack, and a couple beers. Like others I was skeptical at first because of the price, but figured that AM wouldn't put their outstanding rep on the line and sell garbage, and I was right!! I mainly bought them for looks and I got even more than I could have hoped for...Not only does my car finally have that aggressive stance that i've been looking for, but now I've noticed much less body roll in turns, and it just feels great. Of course these alone won't get you any first place trophies at auto cross, but for daily driving, they're definatley worth it! Oh and for fellow 'vert owners, YES they fit and work just fine, go check it out in the pics. Look for the red '00 with the black fr500's...thanks again AM!

    SR springs

    These springs are very worth it.. At first I was worried it wouldn't work for my v6 but it fit just fine.. And the drop seems like it was more than 1.5" it's definitely not slammed but it looks like a mustang should. Also with these springs, the car feels much more solid. My rear end doesn't hop around when I drift and it doesn't roll around nearly as much! Still not the best handling but it's well worth the price!

    Improved handling and aggressive stance

    A friend and I installed these springs in an afternoon. It gave my 'Stang a much more aggresive stance and improved handling greatly. Definitly purchase the isolators with the kit.

    these springs look great

    I just purchased the SR Performance lowering springs and 18 inch Black Chrome FR500 rims, my car looks a million times better :) they were fairly easy to install on my 96 mustang gt, but you will need spring compressors to put them on. Overall a great buy and would recommend to all of my fellow mustang owners

    Can't beat the price for a lower ride

    Lowered my stang with a set of these lowering springs and through it says 1.5 inch it did drop just a bit lower, but it went just perfect in the drop. Not to much, not to little. The ride quality I felt actually became better than the stock springs.

    Great Value

    I used these on an 03 v6 model - The drop was exactly 1.5 inches, measured before and after on the same surface after about 300 miles of driving. I installed new shocks and struts at the same time, and just added the camber bolts which worked perfectly. The only think I was hoping for was a little more sporty of a ride, but I understand it's still a mustang. If you're looking for a drop without compromising much ride quality, these are perfect.
