    Review & Installation Video

    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.

    Improves Handling. Installing a set of SR Performance Progressive Rate Lowering Springs on your Mustang is an inexpensive way to improve its handling performance. These Springs were engineered to lower your Mustang's center of gravity, which will helps to reduce squat during rapid 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.

    Sleek Lowered Stance. A set of SR Performance Springs not only improve the handling performance of your Mustang, but they also improve its overall appearance. By lowering the ride height approximately 1.5" front and rear, that huge tire to fender gap is eliminated. These Springs will provide your Mustang with a sleek, muscular stance that will be sure to get you noticed on the street and at the track.

    Progressive Design. Progressive springs (also known as variable rate springs) are designed to be more compliant when riding over rough and uneven surfaces like public roads. Progressive springs are engineered with a low starting spring rate that increases as the spring compresses. Variable rate compression allows for a smoother ride, while still providing good handling characteristics when pushed hard. This makes progressive rate springs a popular choice for daily street driven Mustangs. 525 lb/in - Front; 250 lb/in - Rear

    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.

    Professional Installation Recommended. Seeing that a spring compressor is required for installation of these Lowering Springs, AmericanMuscle recommends professional installment. With the proper tools, the install can be completed in about three hours. Please note that an alignment is highly recommended after installation.

    Recommended Upgrade. When installing new Springs on your Mustang, you should also replace your old worn out rubber Spring Isolators with a new set of Polyurethane Spring Isolators at the same time, see ordering options above.

    Application. This set of four SR Performance Progressive Lowering Springs are specifically designed for use on 1979-2004 Ford Mustang coupes, including the LX 5.0, V6, GT, Bullitt, Mach 1, and 1993-1998 SVT Cobra models. Does not fit 1999-2004 IRS-equipped SVT Cobras.

    will this cause my car to scrape? will the drop with these springs cause my 02 GT to scrape on speed bumps and such?


    • 1 .5" inch drop most of the time isnt enough of a drop for everyday driving and most speed bumps.things like tire size, ground effects play a part also whether your car will rub or not. most bumps are 6" tall or shorter, measure the lowest place under your car,then take an extra 1.5 " off that and you will have your answer. good luck,pappy

    actual drop? How much will these springs actually lower a 98 cobra? Most of the time it seems springs lower less the advertised.


    • it will take a little time to settle once installed but they will drop to there advertived specs.

    What is gained by getting the more expensive springs These SR Performance Lowering Springs #53150 Look like what I want at a good price. I was just wondering what is gained by purchasing a set of the more expensive lowering springs. I am thinking about with regards to ride mostly. Do you get a softer ride when you spend more money? I would be installing them on my 98 SVT Cobra Convertible Mustang mostly for the looks and don't want to have it riding like a chuck-wagon. I look forward to your input. Fred Wagner


    • I installed mine on my 03 GT. Theyre a progressive spring so they're soft when you're cruising and stiffen up under pressure from what I understand. Great for a DD, but I have no idea how long they'll last.

    Will these fit on the base model 1995 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.


    Show 2 more answers Helpful (2)

    Will the drop differ on a convertible? If so by how much, would the drop still be 1.5?


    • This kit is designed specifically for the coupes due to how the weight distribution and suspension is setup, these springs have a lighter spring rate than that of the convertibles due to the convertible models being heavier than their coupe counterparts. The drop on this kit if used on a convertible would increase by about .1-.15 inches because of the softer rate, also, the ride quality will be effected because of this.

    Is it necessary to install Caster/Camber plates or can i get by without on a drop of 1.5"


    • It is not necessary to install the caster camber plates no. However, without them you are most likely going to have a bad tire alignment.

      Feel great, not too hard to install

      Install Wanted to lower my mustang a bit but was on a budget. These springs are really great for their price. They’re not too hard to install, took me 5 hours granted I didn’t have all the right tools (had to use an adjustable wrench for some stuff). I was able to do it with two hydraulic jacks and a scissor jack. I did the back first then the front. The rear springs probably took around 45 mins each and 1 and a half our for each front spring. You do have to take the brake assembly apart to some extent on the front spring just due to the length of the brake line. Hardest part was probably just getting the old springs out, I would use a crowbar or something. Putting the new springs in is a bit easier since they’re shorter though you still kinda need a crowbar. I’d say it’s a two person job, one pushing the spring in, the other pushing the a member down to make space for the spring. Feel After having the springs in for a week or so, I haven’t had any problem. They feel great, better than the old springs. As a Bay Area resident, the roads are absolute trash so the progressive spring rate helps with all the bumps. You can really feel the stiffer spring rate on turns. A lot less roll and it kinda feels like you be guided into turns. I haven’t had any problems with my alignment although if you did it’s not too hard to fix. Look You really don't notice anything while driving but when you’re looking at your car from the outside, the difference is huge. It’s nothing close to a JDM drifting car but it’s great for the daily driver and someone who doesn’t plan on drifting on every turn. General I’m sure you can get better springs for a higher price. That’s just a given but for the price, these springs are probably the best mod in my car. Even if you didn’t want to get the springs for their stiffer spring rate, I’d still get them just because they’re simply better than the original springs. They are 100 worth it and for the price, I doubt you can find anything better.

      Dropped my car two inches. Not very stiff, the car rides great, but it still helps out a ton in the corners. One thing I realized, the car spins the tires a lot easier now, less weight transfer to the rear wheels.
