Review & Installation Video

I’m Justin from AmericanMuscle.com, 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.

SR Performance Lowering Springs. 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. These springs not only improve handling, but they also improve the appearance of your Pony by lowering the ride height approximately 1.5" to eliminate that ugly "4x4" tire to fender gap, for a more aggressive street stance.

SR Performance Caster Camber Plates. After installing a set of SR Performance Springs on your Mustang you will need a proper front end alignment. SR Performance caster camber plates will allow you to fine tune your Mustangs front end geometry to prevent premature tire wear while improving steering input and response, turning your Pony into a real corner carver.

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 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.

Why won't these springs fit the 2.3 na models?

AustinW

  • Hey Austin, The springs themselves technically will fit, but the spring rate wont drop the car like it would its 5.0 counter part. The weight difference plays a huge factor when it comes to springs and how much the car is lowered. With yours being lighter it may not even drop it at all.

Will the 1.5" drop affect the fit of 17" pony wheels? ('93 LX Notch)

PeteZ

  • Rim size increase with the correct tire does not increase the overall diameter of the wheel, so there will be no impact (no pun intended).

    SR Performance Springs and Caster plates

    I purchased this kit because of the positive reviews and I was not let down. The springs ride very nice and firm but not hard. These springs lowered my mustang 1.5" all the way around and the stance was perfect! Installation was a bit difficult because of the lack of installation but nothing to complicated. I would highly recommend you purchase the spring installation tool for this job. The caster plates didn't come with instruction but sent customer service a request and they quickly sent me instructions. I would highly recommend this kit to anyone looking for a good cheap alternative. I normally use Eibach spring and they are just as good.

    Awesome stance!

    The lowering springs and camber caster kit gave my mustang a killer stance, way more aggressive. I highly suggest finding a spring compressor, it made the job way easier. The car rides a lot firmer and handles noticeably better.

    Good bang for the buck, but thats about all

    I installed these on my 1991 LX Conv. The springs work but the ride was horrible on bump roads. I would bottom out on just about every bump especially if I had a passenger in the back seat. It does look good and gave it an aggressive stance but handling was not good. I ended up putting my stock springs back in. The drop was probably over an 1.5 inches in the front and almost 2 inches in the rear. The caster/camber plates are not real heavy duty. the hardware is also on the low end of the performance spectrum. The bushings are soft and will flex quite a bit. If I had to do all over I would have spent more money on a different type of plate. Fit was mediocre but finish was nice. Look at the BBK or better brand.
