Review & Install Video
Hey, guys. Alex from americanmuscle.com, and today I'm bringing you my detailed review and breakdown of the BMR Lowering Spring Kit, fitting your 2015 through current Mustang GT. So in this video, I'm gonna talk about who this kit's going to appeal to, what you should be expecting in terms of the look as well as the handling and performance that you're gonna be getting out of this kit, the construction and materials that went into this, what you should expect to be spending. And then, lastly, we're gonna take a quick look at what's entailed to get these installed on your car. Probably be giving this a light to a moderate one out of three wrenches on the difficulty meter and about three to four hours' worth of wrenching, and I'll have a little bit more for you on that later.
So if you're the owner of a 2015 through current Mustang GT and, first and foremost, you are just not too thrilled with how it sits and you're looking to drastically improve your handling, acceleration, and braking by means of lowering your center of gravity, I would definitely suggest checking out this kit for your car. Chances are you're probably more interested in the look that this is gonna give your 2015 through current Mustang. You're gonna be looking at 1.2 inches up front and a 0.5-inch drop out back. Now, don't get me wrong. It might sound like it's a little, if not a minimal, drop. Check out some of the pictures on the product page. You're gonna see that this is definitely gonna drop the car very nicely, and depending on whatever type of wheel and tire package you're running, no matter if you've got a 305 out back or a 275 or a 285, it's just gonna shrink that gap really nicely and give it a very aggressive stance.
So getting into the thick of things here, while the S550 Mustang is a great performer right off of the dealer lot, Ford left a ton off the table here, as this car's gonna be comfortable from anyone to the age of 16 all the way up to their 70s. But if you're pretty in tune with how your car drives, you like to drive pretty spiritedly or aggressively, you probably noticed that the S550 does have a tendency to exhibit a fair amount of diving, squats a little bit. The handling can be a little bit all over the place as well. The great thing about springs, not only are they gonna clean up that wheel gap and make it look that much more aggressive, but by lowering that center of gravity, it's just gonna make the car planted that much better, which in turn is gonna help your handling as well as the acceleration and braking.
One thing that I definitely don't like about the S550 GT is, despite the fact that you've got a really heavy motor up front, the front end does not feel that connected. That's just something I don't like, and, once I drove a car equipped with a set of lowering springs, especially this kit right here, it was feeling that much more direct and in tune and connected. Which, at the end of the day, not only is it gonna make you that much of a happier driver, but it's gonna make you that much more confident when running your car through its paces.
I wanna call it out right now that these are gonna be a standard or a linear style spring, as opposed to a progressive spring, which essentially means that these are going to ride a little bit stiffer. But at the end of the day, if you're gonna be lowering your car, the ride quality will suffer slightly, and it's really something you're not gonna be able to get away from. So looking into this further, I actually think that a linear spring, or a standard spring, is gonna be that much more competent on the roads in comparison to a progressive spring because it's gonna be that much more predictable, as it's not gonna be pitching as you would find with a progressive rate spring, which essentially is gonna adjust itself, based on the amount of load that you're putting it to. So the flip side, if you're wondering how a progressive spring is gonna act or operate in comparison to a linear, it's gonna be that much more softer. But once you're running the car through its paces, it's gonna get that much more stiffer, due to the amount of load that you're putting it towards.
So if you're new to the S550 Mustang or if you've been running around in your car for a couple of years now, you may or may not have heard of BMR. This team is a bunch of drag racing lunatics. Their parts are made, tested, and abused consistently here, right here in the U.S. These guys ultimately wanna bring you one of the best driving experiences possible, not only just looking to help your car look better, but to make you that much more competent of a driver behind the wheel.
So down to brass tacks here, guys, we're gonna see that BMR's gonna have these manufactured out of a CNC cold form high-tensile spring wire, which is typically what you're gonna find most, if not all, suspension companies using. So to eliminate some of the stresses that springs go through during the manufacturing process, once these are out, BMR's gonna put these in a very high-temperature oven, have these baked at around 750 degrees, to ensure that you're not gonna have any issues down the road with these failing. Now, one thing that I really like about BMR is that they're gonna guarantee that these springs are not gonna sag over time, something like you might find with an inferior spring.
So in terms of the pricing here, you should expect to be shelling out about 260 bucks for this kit. My opinion, is gonna be right damn near in the middle of the road for most, if not all, spring kits for the 2015 through current Mustang. But what you're gonna be getting here is gonna be a quality-built, U.S.-manufactured and designed part that's gonna drop your car very subtly. But again, take a look at the pictures on the website just to get a better idea of what I'm talking about. Not only is it gonna make it look that much better, but it's actually gonna help you handle, accelerate, and brake that much more effectively.
So switching gears to the installation portion of the video, just like I had said up top, you're gonna be looking at a pretty involved one out of three wrenches on the difficulty meter and easily three to four hours' worth of wrenching before you get these onto your car. So looking ahead, some things that I make sure to have on site here, full socket set, maybe a couple of race ramps or jack stands, a case of beer, and a little bit of patience.
So to start, you're gonna wanna get the car on a set of jack stands, pull your wheels and tires, and then start with your sway bar end links. And then you're gonna wanna move over to your calipers and brakes and start pulling out as much as you can. Once that's done, you're gonna need to get under the hood and then pull the three bolts that are gonna be attaching the top of your strut mounts and the assembly, and then pull those out of the car. Moving towards the back of your Mustang, assuming your wheels are already off, you're gonna need to remove the lower shock bolts, followed by the bottom bolt on the vertical link, and then remove the lower sway bar end link.
So while I know it's much easier said than done, this is gonna be a quick glance of what's entailed to get these onto your car, and, once your factory components are out, it's gonna be as simple as swapping back your BMR Springs into the car, buttoning everything back up, and then taking it down to get a good alignment.
So just to wrap things up here, some final thoughts. I definitely like this option for the 2015 through current Mustang GT, based on a couple of different facts here. First and foremost, BMR is dedicated to giving you some of the best driving dynamics and an overall great experience out there. These guys love to drag race. They test and beat their parts repeatedly. Not only that, lowering spring kit's gonna make your Mustang look that much more aggressive as well as reducing some of that side-to-side slop as well as giving you better acceleration and braking by means of lowering that center of gravity.
