Review & Install Video

Hey, guys, Stephanie with americanmuscle.com, here with these Whiteline Lowering Springs for 2015 and up S550 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 in the difficulty meter. The Whiteline Lowering Springs are gonna be a good option for those of you out there that are looking for a lowering spring for a daily driven car or a street car that's gonna give a good drop but that's designed to be used with the factory shocks and struts. These springs are made to provide balance with both OEM and aftermarket shock and strut setups. While a lot of other springs out there function better with aftermarket setups, these springs offer a drop of 1.3 inches in the front of the car and 1.1 inches in the rear. Now, this is what I consider more on the standard side in the world of lowering springs for the S550. Currently, you tend to see that the majority of springs offer a standard a one-inch drop, and the largest drop that you'll find in the spring for the S550 is just over one inch. These springs offer a touch more than that in the front and in the rear. But even though that is the case, these are still gonna be compatible with both the factory and aftermarket wheel and tire setups. The plus side of the S550 looking so good and responding so well to a little bit a lowering is it can create a functional low. And by that I mean it's low enough to look good but not low enough to cause issues either on the tire or under the car. It's gonna leave you with a very streetable car still. And, of course, a lowering spring is gonna lower the center of gravity to provide some handling improvements, like reducing squat and body rolling corners, and eliminating nosedive under hard braking. Just keep in mind that the drop of these springs will look a touch different and depending on your exact wheel and tire setup. The other thing to consider when you're shopping for springs besides the drop is the ride quality. These springs do have a performance design, so they're made for street and race applications, but they do it without compromising ride quality, which means that they're gonna be a good option for a street car. They don't have a harsh ride quality, but they are a firm spring. The ride is more stiff, and you do notice more road noise. Other than that, you'll just notice the other benefits that I mentioned earlier, the car having less body roll and being more planted overall. These are a progressive spring, which means that they'll be more forgiving on the street than say a linear spring would be. As far as price, these springs are gonna cost between $200 and $300, which is right where the majority of other springs are falling as well. Of course, there are some springs that are either less expensive or more expensive than that, and even springs that are all across this price range. So, the install here is gonna take about four hours. I'm gonna call it a solid two 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. 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 assemblies, so everything like the wheels, the brakes, and 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 in 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 it's nothing crazy. Essentially the IRS subframe will be dropped along with the rear shock mount so you can slide the rear springs out. Just like the front, the rear springs install the same way they're uninstalled, there's no surprises there. The bump stops are slid on to the shock, followed by the factory dust boot. 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 Whiteline Lowering Springs offer a 1.3 and 1.1-inch drop in the front and rear respectively, and they're a performance-based spring designed for street and occasional track use. As always, I suggest you check these out more online for yourself. And for all things Mustang, keep it right here at americanmuscle.com.

Exceptional Performance. Lower the center of gravity of your GT Mustang with a set of Whiteline Progressive Rate Lowering Springs. By lowering your Mustang's center of gravity, you will see a reduction in squat during acceleration, body roll in the corners, and excessive nose-dive under hard braking. Whiteline Springs bring optimal handling performance to your S550 Mustang while upgrading its overall appearance.

Lowered Stance. Not only does a set of Whiteline Lowering Springs improve the handling performance of your S550 Mustang, but they also improve its overall appearance. By lowering the ride height approximately 1.37" (35mm) in the front and 1.18" (30mm) rear, that massive tire to fender gap is eliminated, providing your Mustang with an aggressive muscular stance.

European Precision. WhiteLine Springs are developed and manufactured in Europe from the highest quality materials available. Engineered for optimal balance with either OEM or aftermarket shocks, these Whiteline Lowering Springs have been specced to the finest tolerances for a guaranteed exact fit. Whiteline completes their Springs in their signature silver powder coated finish for exciting good looks and long lasting corrosion resistance.

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.

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 Coil Springs, AmericanMuscle recommends professional installation. With the proper tools, installation can be completed in about three hours. Please note that an alignment is highly recommended after installation.

Application. This set of four Whiteline Lowering Springs are designed to fit the 2015-2017 GT Mustangs.

Do you have to purchase cambers for these to install or are they already ready for install

  • Hello! We do recommend getting Caster Camber plates for anything that will lower your car over an inch. With the Whiteline Lowering Springs you can expect a drop in the Front by 1.37" & Rear by 1.18" so we definitely recommend you get the plates to stay within factory alignment specs

Does it include new bump stops for the front and rear shocks? And new front dust boots?

    whiteline springs

    The springs are great quality, it was soppose to drop the car a little over 1 inch, but it gave the car about a 1 inch drop all the way around. The ride is fine, very similar to stock.
