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.

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.

    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!

    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.

    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!

    very rough for a small drop

    Only lowered car 1" but feels slammed. Very firm ride. They do prevent alot of body roll and help handling on smooth pavement, But anything stiffer than stock will do that. Not really happy with these, but if you want super stiff springs with a subtle drop these are perfect for you. Mine will most likely come back out.

    • Response from AmericanMuscle

      If you installed these lowering springs along with stock shocks and struts, that could be the cause of a much stiffer ride. This hasn't been feedback we've seen in the past so I would highly recommend upgrading those suspension components. If you'd like any suggestions or help figuring out which shocks and struts would be best, don't hesitate to give us a call - we'd be happy to help!

      These springs will definitely fit a V6, but the spring rates were specifically designed with the extra weight on the V8's in mind. While you can get these installed on your car without a problem, you're not going to get as big of a drop as you will with the GTs. Just something to keep in mind!

    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.

    Absolutely garbage springs. Do yourself a favor and invest in a nice brand name spring set. Had these on my car and very happily upgraded from the SR springs to HandR springs. The car now rides much smoother and doesn't slam on bumps. It's more firmly planted and handles better. Stay away from this junk.

    Looks good dont like anything else

    I thought I would like these springs based on reviews. As it turns out the people that gave these a good review either never had lowering springs before or a quality spring. I installed these with Kong str.t.. A quality lowering spring does not need time to settle, you get what you get out of the box. These do need to settle and they are extremely bouncy out of the box, not a stiff bouncy almost like a riding with no shocks bouncy. After they are settled the ride height looks good, but I would not call these a lowering spring by any means, I would compare to an overpriced ebay spring. I will be removing these and going with something else
