    Review & Installation Video

    Review & Install Video

    Hey, guys. Stephanie with americanmuscle.com here with a review and install of the BMR Lowering Springs fitting 2015 and newer S550 GT Mustangs. We're going to be talking about a few different things with these springs but mostly we'll talk about what you can expect from these springs in both the performance and looks categories and we're also gonna talk about the install as well. We'll talk more about the install later but you're looking at one out of three wrenches on the difficulty meter. The BMR Springs are going to be a good option for the GT owners out there who are looking for a linear spring that'll give an aggressive drop and more aggressive handling. This spring is perfect for those owners out there that are looking to have more of a muscle car stance and still maintain ride quality. Lowering springs have a big impact on both the looks and handling of the S550 and these offer a pretty big drop in the front and slightly less of a drop in the rear. These springs will drop the GT about 1.2 inches in the front and a half an inch in the rear of the car. And like I said, it doesn't get much lower than this for the front of the S550 from the spring and it may not sound like it, but this is a pretty big drop. Depending on your wheel and tire setup, this drop is going to eliminate a lot of the wheel gap that the car has from the factory and it's going to leave the car sitting a little above the tires. But of course, that can change depending on what size wheel and tires you're running. Now, a one-inch drop or just under a one-inch drop is pretty standard across the board for this year range. The car sits pretty high on a factory setup so the 1.2-inch drop that these springs offer for the front of the car and even a half inch drop in the rear is still aggressive. I mean aggressive in both looks and performance changes. This drop will lower the car's center of gravity enough to create more track like handling capabilities. These springs are really gonna reduce squat during acceleration and reduce wheel hop as well. You're also looking at much less body roll during cornering and less nose dive on your braking. Lowering the center of gravity this much means that these springs are really gonna change and tighten up the handling of these cars. Now, if you think these springs have too much of a drop for you or you want to hang on to some of those softer ride quality characteristics, there are a ton of other spring offerings you guys can always check out. Now, these springs do offer a good amount of drop but this doesn't mean that the springs won't work on a daily driven car. They'll work just fine. It really all comes down to your personal preference and what you want out of the springs. These springs were specifically designed for the street performance crowd so you can expect to stay away from the rough ride quality features that you can sometimes see with other options that are geared more towards drag racing use. Now, with that being said, I want to mention that these are linear springs. These are not the progressive rate springs that we tend to see that are going to change as you drive. Linear springs have a constant rate of force per inch. So they tend to have one defined spring rate and that's it. So basically, as the load on the springs increase, the spring compresses an amount directly proportional to that load and this makes a linear spring more performance oriented than a progressive rate spring. Progressive rate springs are variable rate springs. They have low initial spring rates that increase as the spring is compressed which makes for a softer and smoother ride quality. But keeping the drop of these particular springs offer in mind, they are still going to work with both the factory wheels and the preconfigured wheel and tire kits that are on the site. These kits aren't going to make the car difficult to drive places but you will need to be a little bit more careful. They are going to be stiffer than the factory springs as well so you will notice some more road noise. But I wouldn't say that these give a bad ride quality at all. They're just not as soft as factory. I do want to say that a lot of times when you're shopping for lowering springs, you're also shopping for things like adjustable caster camber plates and a new set of both shocks and struts. In this case, I wouldn't say that caster camber plates are necessarily required. A 1.5-inch drop is about the limit of where you need a set of adjustable CC plates in order to get the alignment back within spec and these springs won't drop the car that much. but a set of caster camber plates wouldn't be a bad idea at all. At the end of the day, it never hurts to have caster camber plates so if you've got the extra cash, I'd say go ahead. But in all reality, you will be able to get away without picking up a set. As far as shocks and struts, this goes back to the drop too. I'd say that you can get away with the factory shocks and struts in this case due to the fact that you aren't really slamming the car here. But I would still keep in mind that these are a linear spring. They're not the more forgiving progressive springs, so shocks and struts are something that you might want to consider. I'd say that you can get away with running your stock components if you have some components with a relatively low mileage. If your shocks and struts have a ton of miles on them, I would replace them. But in this case, since we're talking about relatively new cars here, you can probably get away without it as long as you don't have a ton of miles. When it comes to price, it all depends on how you buy these springs. BMR offers a full set for just over $200 or you could purchase just the front or just the rear springs. The front springs alone will cost a $100 and the rears will cost just over a $100. So you do have some options there. Now, as far as price for the set of springs goes, these springs are going to be one of the middle of the road options. They're not the most expensive but they aren't the least expensive either. If you're just looking to get your car low and you aren't concerned with ride quality, there are some other options on the site that'll cost a little less and will get you where you need to be. So the install here is gonna take about four hours and I'm going to call it a solid one out of three wrenches on the scale because you will need some knowledge to complete the install. So I'd recommend having a knowledgeable helping hand or taking this to a shop for the install if you haven't done this before, especially since it's always a good idea to get an alignment after the install anyway. This install can be done on jack stands if you don't have access to a lift. But as usual, a lift would be your best bet here. You're gonna need a few tools including a spring compressor so make sure you have that before you start the install. You're gonna need to get down to spring and strut assembly. So everything like the wheels, the brakes, the ABS lines will need to be moved out of the way so you can pull the assemblies out of the car. The spring compressor will help you remove the spring from the strut and install the new front springs which are compressed and installed the same way. The strut assemblies go back the same way they came out and the install is the same for both sides. The rear is where things are a little different but nothing crazy here. Essentially, the IRS subframe will be dropped along with the rear shock mounts so you can slide the rear springs out. Just like the front, the rear springs install the same way that they were uninstalled so there's no surprises there. New bomb stops are slid onto the shocks followed by the factory dust boots. And the new springs can be installed and the IRS subframe can be bolted back up and that's about all it's gonna take. Like I mentioned earlier, a fresh alignment after the install isn't a bad idea. Wrapping things up here, the BMR Lowering Springs are a linear spring with an aggressive drop, an improvement in handling that will make for a street car that feels track ready. They'll drop the car 1.2 inches in the front and a half inch in the rear giving a muscle car stance. The springs are not difficult to install, they're in the middle of the pack as far as pricing goes, and you can check them out more online right here at americanmuscle.com.

    Performance Handling. BMR Suspension designed their Performance Lowering Springs with the street performance crowd in mind. Featuring a linear spring rate these BMR Performance Lowering Springs will lower your S550 Mustang's center of gravity, reduce squat during acceleration, body roll in the corners and excessive nose-dive under hard braking. BMR Performance Springs provide great handling and a smooth ride making them ideal for a variety of street applications.

    Sleek Muscle Car Stance. Not only does a set of BMR Springs improve the handling performance of your Mustang, but they also improve its overall appearance. By lowering the ride height approximately 1.2" up front and 0.5" in the rear these BMR Performance springs will eliminate that huge tire to fender gap, for a sleek muscle car stance.

    Superior Construction. Designed and manufactured in the USA, these BMR Lowering Springs are CNC cold wound from chrome silicon high-tensile spring wire. To guarantee that their springs will not sag over time, BMR fully compresses every spring twice to permanently set the spring. To eliminate the stresses induced during the winding process BMR springs are stress-relieved at 750 degrees F. Shot-peening is then used to eliminate any residual surface stresses. As the final step every spring is compressed and tested allowing BMR to offer a Lifetime Warranty against spring sag.

    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.

    Choice of Options. BMR Performance Lowering Springs are available as a pair of two Front Springs, a pair of Two rear Springs or as a complete set of four. BMR even offers a pair of Minimum Drop Front Springs that are ideal for use with aftermarket supercharger or turbo systems that require a little more ground clearance. Please select from the options listed above.

    Application. These BMR Performance Lowering Springs are specifically designed for use on 2015 to 2019 GT Mustang Coupes or Convertibles equipped with independent rear suspension (IRS). Not intended for use on V6 or EcoBoost models.

    Technical Note. The Springs are not compatible on vehicles equipped with the MagneRide Suspension.

    5 Top Rated Questions

    Do I need a set of caster camber plates with the minimum drop front springs, or will they align within spec without them?

    • For these BMR Lowering Springs you would want at the very least to have camber bolts though caster camber plates would be better and recommended for these springs.

      Definitely a must buy , if you live in a city with terrible roads where you can’t be to low. 20s in the rear and 19s up front. I have no wheel gap. The car doesn’t dive on hard braking and it stays stable as you drive down the road. Amazing feel, very close to stock.

      Just put these on and man does it make the car look so much better. Not too low, but enough to enhance the look and feel. And under acceleration and braking theres no more nose dive or lifting. Rides as close to stock as you can get with aftermarket springs.

      Nice stance.

      Great springs which give the car an aggressive stance. The nice thing about BMRs Performance springs is that they are designed to work with your stock shocks. Installing these was very straight forward. If install them yourself, and you use the basic spring compressor rental from Autozone, then I suggest tapping up the metal parts that contact the springs. If you don't your springs will get scratched up.
