Hey, guys. Stephanie with americanmuscle.com, here with a review and install of these BMR Lowering Springs for 2005 to 2014 GT Mustangs. We're gonna 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. I'll talk more about the install later, but you're looking at a two out of three wrenches on the difficulty meter. The BMR Performance Lowering Springs are gonna be a good option for the GT owners out there who are looking for a spring that'll perform for both the daily driver and the drag car. These are a crossover spring that are made to function in both worlds. So they're soft enough for the track, but they give enough support to keep the body of the car flat and level through corners. Lowering springs have a big impact on both the looks and handling of the S197 chassis and these springs are a linear spring that are gonna offer a pretty big drop to these cars. These springs will drop the GT about one and a half inches all the way around the car, and like I said, it doesn't get much lower than this for the S197 from a lowering 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 gonna eliminate a lot of the wheel gap that the car has from the factory that's gonna leave the car sitting nice and even a little bit above the tires. But of course, that can change, depending on what size wheels you're running. So a one-inch drop or just under a one-inch drop is pretty standard across the board for this year range. This car sits pretty high from the factory, so the one and a half inch drop is pretty 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 during braking. Now, these springs do offer a good amount of drop, but it doesn't mean that they're not gonna work for a daily-driven car. They'll work just fine. It really all comes down to your personal preference and what you want out of these springs. These springs were specifically designed to be that crossover spring between both drag racing and daily driving, so you don't have to worry too much about a rough ride quality. Now, with that being said, I wanna mention that these are linear springs. These are not progressive rate springs that we tend to see that are gonna change as you drive. Linear springs have a constant rate of force per inch, so they have one defined spring rate and that's it. And these springs have a 220-pound spring rate, 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, or variable rate springs, have a low initial spring rate that'll increase as the spring is compressed, which makes for a softer and smoother ride quality. But keeping the drop that these particular springs offer in mind, they're still gonna work with both the factory wheels and tires and the pre-configured wheel and tire kits that are on the site. These springs aren't gonna make the car difficult to drive places, but you will need to be a little bit more careful. They are gonna 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. It's just not as soft as factory. I do wanna 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, but I will say that a one and a half inch drop is about the limit of where you'd need a set of adjustable CC plates in order to get the alignment within spec. It's gonna be close, so a set of CC 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 go, this goes back to both the drop and the fact that these are linear springs. I will say that, in this case, if you have some components with relatively low mileage, you're probably gonna be okay. If your shocks and struts have a ton of miles on them, then I would replace them, but in this case, since we're talking about relatively new cars here, you can probably get away with 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 about $200, or you can purchase just the front or just the rear springs for $100 each. So you do have some options here. Now, as far as the price for the set of springs goes, these springs are gonna be one of the middle-of-the-road options. They're not the most expensive, but they're not the least expensive, either. If you're just looking to get your car lower 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 gonna call it a two out of three wrenches on the scale. You'll need some knowledge to complete the install, so I'd recommend having a knowledgeable helping hand or taking to this to a shop for the install, especially since it's always a good idea to get an alignment after the install anyway. The 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. 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 the spring and strut assembly, so everything like the wheels, brakes, and 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's the same for both sides. The rear is nearly the same. You need to disassemble some items to get to the springs, but ultimately, you'll be able to lower the rear axle to the point there the springs will be free. Just like the front, the rear springs install the same way they were uninstalled. Rubber insulators are transferred over, and new bump stops can be installed. And after the new springs are in, you can begin reinstalling the shocks and everything else you want installed, and that's about all it's gonna take. And like I mentioned earlier, a fresh alignment after the install isn't a bad idea. Wrapping things up here, the BMR Performance Lowering Springs are a linear spring with an aggressive drop and improvements in handling to make for a car that feels track-ready. They'll drop the car one and a half inches all the way around and will leave the car sitting just above the wheels and tires. These 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.

Can someone give me a yes or no answer on whether or not I will need a camber plates or panhard bar when I am installing these on my 2013 California Special convertible? I don't understand why someone can't give a straight yes-or-no answer why is it a maybe?
You may need the caster camber plates when installing the BMR Lowering Springs. It all depends on how out of alignment the suspension is after the install. After installing, we highly suggest getting an alignment. If the shop cannot get the suspension back to factory alignment, then you will need to get caster camber plates or camber bolts.
Are these rear springs progressive ?
These would be a linear spring.
Okay, so should i get pan hard? Or it will work with stock?
When lowering your vehicle, we highly recommend a panhard bar as this will help keep the rear axle centered.
Will a 295/35/20 rear 255/35/20 front tire rub at all with these springs??
Tire fitment will depend on wheel offset/backspace and wheel width, however with typical aftermarket Mustang wheels, you should not experience rubbing.
Will 305/30/20 be ok with these springs. 2013 Mustang GT
Tire fitment will depend on your wheel width and backspacing, however with 1.5" typically this size will be pretty tight for clearance.
The BMR Lowering Springs will increase handling and reduce body roll due to their stiffer spring rate. Because of this you will find that ride quality will slightly suffer.
The BMR Lowering Springs will work on a track pack car, however as the track pack car is already lowered, the total drop with these springs will be less. Track pack cars will see approximately 0.75" of lowering with these springs.
These BMR Lowering Springs will re-use your factory bumpstops. These will not require the use of any aftermarket bumpstops for proper installation.
20x10 wheels would be fine with these springs on your car.
The BMR Lowering Springs will have no problems working with your stock 19" wheels.
The BMR Lowering Springs will work well with all of the shocks and struts we sell, however we recommend the KONI STR.T Shock and Struts.
Yes, these BMR Performance Lowering Springs will fit on your 2006 GT convertible.
The BMR Performance Lowering Springs can be used with your 2013 Mustang GT Convertible.
You will be able to use a fixed panhard bar with the use of these lowering springs.
Hello! The higher spring rate of the SR Performance Lowering Springs means it will be a little stiffer of a ride, with less spring travel compared to the BMR Lowering Springs - Performance springs.

Best springs for all mustangs
I live in the bay area California. I tried two progressive spring brands before this and these is by far the best springs. frpp and Roush was super uncomfortable on bad roads, the spring rate sky rocketed like crazy all the time. These standard springs feels like stock. And don't forget there's a lot that goes into lowering your s197: Camber plate Bump steer tie rod end Extended ball joint LCA relocation bracket Shorter bumpstops (FRONT and rear) Adjustable pan hard bar Adjustable UCA (if one piece driveshaft is equipped). Consult AM or Your suspension shop for more info.

Perfection!
Although there isn't much that goes in to replacing your Springs these were the perfect product to make my car sink down and give it that handling I needed the inch and a half drop was the perfect amount to still give myself space between the tires and the wheel wells she looks beautiful and I couldn't be happier.

BMR Rear only Lowering Springs
Easy to install, one extra step due to convertible structure supports. Ride was not compromised, actually it was vastly improved (less nose dive on decel, less rear squat on accel, less oversteer on corners). AND it looks far better with the elimination of the rear 4x4 look and factory rake. One of the best mods I have done in some time to my Stang.

Amazing!!!
This should have been the first mod I made. With these springs and some spacers my Stang handles great and looks great!

These worked great to lower my 05 GT
Installed these with a set of Ford Performance Dynamic Shock and Struts. They did a great job of lowering my 05 Mustang GT. Much better handling with the lowered center of gravity.

Much better!
Car rides smooth, not harsh at all. Was looking for something comfortable that gave the car a good look with the drop and these delivered. If your looking for springs that will lower your car, improve handling and ride smooth, these are the springs.

Easy install
Was an easy install as I also replaced the struts. Since mine is a convertible, I had some under car braces to remove first. Took me about four hours to install the springs and Panhard bar. The car sit right in my mind. Ride has firmed up some, but that was expected. Glad to not look like a 4x4 anymore. Installed the BMR Panhard bar as well. Love the BMR products.
