Review & Install Video

Hey, guys, Stephanie with americanmuscle.com here with an install and review of the Ford Performance Track Lowering Springs for 2015 and up S550 GT and EcoBoost 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 the 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 Ford Performance Track Lowering Springs are gonna be a good option for those of you out there that are looking for a lowering spring, that's gonna provide aggressive handling. These springs are specifically designed for track use and track-like handling, and they're made to be used with the Ford Performance shocks and struts, not your factory shocks and struts. These springs offer a drop of 1 inch all the way around the car and as far as lowering, this is one I consider more in 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 1-inch drop, and that's because this chassis doesn't need a big drop in order to see some improvements. Even though that is the case, these springs are 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 of lowering is it even create a functional low. So, 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 roll in corners, and eliminating nosedive under hard braking. Just keep in mind that the drop that these springs offer will look a touch different depending on your exact wheel and tire setup. The other thing to consider when you're shopping for springs besides the drop is ride quality. These springs do have a performance design and they're made for track use only. They're also made to be used with the Ford Performance aftermarket shocks and struts, so you can bet that these are gonna give you a much different ride quality. You can expect a much firmer ride with the shocks and struts in these springs. I wouldn't describe it as a bad ride quality, but you will notice a big difference. 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, so be sure to check out all of your options so you can make sure that you're choosing the right spring for you. So, the install here is gonna take about four hours and I'm gonna call it a solid two out of three wrenches on the scale, because you will need some knowledge to complete this install. So, I'd recommend having a knowledgeable helping hand or taking the car 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. 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 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 the spring and strut assemblies, 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 in the same way they came out, and the install's the same for both sides. The rear is nearly the same, you need to dissemble some items to get to the springs. But ultimately, you'll be able to lower the rear axle to the point where the springs will be free. Just like the front, the rear springs install the same way that they were uninstalled, there's no surprises there. Your rubber insulators can be transferred over, a new bump stops are installed. And after the new springs are in, you can begin reinstalling the shocks and everything else that you uninstalled. 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 Ford Performance Track Lowering Springs offer a 1-inch drop, and they're performance-based spring designed to be used with aftermarket Ford shocks and struts to give track-like handling performance. As always, I suggest you check these out more online for yourself. And for all things Mustang, keep it right here at americanmuscle.com.

Track Handling. Installing a set of Ford Racing Y-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. Ford Racing Y-Springs are intended for track use only.

Aggressive Stance. The Ford Racing Y-Springs not only improve the handling of your S550 Mustang on the track, but they also improve the overall appearance by lowering the ride height approximately 1.0" to eliminate that nasty raised 4x4 truck look for a more aggressive muscle car stance.

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.

Required Upgrade. These Ford Racing Track Lowering Springs were specifically designed to work with Ford Racing Shocks & Struts (M-18000-F) and Sway Bars (M-5490-E), it is not recommended to use these Y-Springs with the stock shocks and struts.

Application. This set of four Ford Racing Track Lowering Y-Springs are designed specifically for use on the 2015-2017 GT and EcoBoost Fastback Mustang models. Does not fit convertible models.

  • The Ford Performance Track Lowering Y-Springs - Fastback do not include the Jounce Bumpers. The Ford Performance Jounce Bumper Kit (15-17 All), item # 388772, can we found at this link: http://www.americanmuscle.com/frpp-jounce-stops-2015.html.

    Impressed

    I've had these installed for about two weeks now and I like them a lot. I paired them with the Ford Racing Shocks/struts. The result is a very firm riding car. Definitely firmer than stock base suspension but not overly harsh. On normal roads the car absorbs most of the minor bumps and the ride quality is pretty good. I think the progressive spring aids the ride quality as well. Handling is much better than stock and the car feels more glued to the road. May be a good way to improve handling and maintain some of the reasonable ride quality.

    Y-springs

    Took a little bit to get the springs in the car but once it was done I could tell a difference. It looked like it sat better with a more muscle stance do to it being lower in the front. Handling you can tell a little difference. It's a little tighter in the corners. Overall. I would say that this is a good bang for your buck under 300. No it's time to get some wheels!!!

    ford performance track springs

    Just got these installed finally. I didn't really know what to expect from these, but I am extremely happy with the purchase. The lower ride height is fairly discreet which I like. The ride quality is not horrible, definitely more stiff but I suppose ride quality just isn't a huge priority to me. The biggest difference is the tight cornering/turning. I wasn't expecting much of an improvement from lowering springs but I was pleasantly surprised.
