Hey, guys, Stephanie with americanmuscle.com, here with an overview and an install of this Ford Performance Street Handling Pack for the 2015 and newer S550 GT and EcoBoost Mustang. In this video, we're gonna cover a few topics with this handling pack. We're gonna talk about the different components, the performance you can expect, and go over the install as well. I'll get into more detail later, but I could tell you right now that the install for this kit isn't hard but there are quite a few pieces, so it's gonna be a little time-consuming and a little bit of work. That being said, I'm gonna call this install a two out of three wrenches in the difficulty meter.The Ford Performance Street Handling Pack is gonna be a good option for the S550 owners out there that are looking to do some handling upgrades to get their car to perform like a performance packed Mustang. If you're looking for the handling characteristics of that performance packed car but you missed out on getting that package when you purchased your Mustang, this kit is gonna get you there. This kit includes all the same components that come with a performance pack and it's a complete suspension upgrade kit. What's more is that you have the peace of mind to know that all of the components are gonna work well together and that all of the most important areas of the suspension are taken care of.This kit has some of the most important suspension upgrades that are really gonna change the handling performance of the car. It has a performance pack front and rear shocks and struts, a set of Ford performance street lowering springs, performance pack front and rear sway bars with bushings, performance pack rear tow links, all the required hardware, and front and rear jounce bumpers. So, if you didn't get a performance packed car, then the factory suspension is set up more for having a comfortable ride quality and being easy to drive in anything else, which is why there's so much room for improvement. [inaudible 00:01:37] wants something more than comfortable, they want effective, and this handling pack is gonna help get you there.Usually, in order to get better suspension performance, you need to take away some ride quality since a lot of the ride quality comes from soft rubber bushings and components that allow for twisting. Taking away too much comfort, however, leads to an uncomfortable ride, notice all the little bumps in the road. Overall, this kit does give a stiffer than factory ride quality when you compare it to the non-performance packed cars, but it's still a factory suspension, so you know it isn't gonna be rough at all.We're gonna talk a little bit about each component, and the first thing we're looking at is the Ford racing street lowering X-springs. These springs are gonna have an even one-inch drop all the way around the car, which doesn't sound like much, but that's a pretty decent drop for the S550 chassis. The S550s respond a lot more to a little bit of a drop from the lowering spring, so it doesn't take much to get these cars looking and driving better. The springs are enough to make a noticeable difference in both handling and [inaudible 00:02:32]. The street springs do have a progressive spring rate, which means that they're a good option for a streetcar. They don't have a harsh ride quality, but they will firm up as you start pushing the car, which works to give you the best of both worlds between comfortable and functional.Moving on to the shocks and struts, you're looking at pre-assembled front struts with the new upper strut mount, which is nice because Ford racing is taking a little bit of the work out of the install for you. You won't need a spring compressor now since these things are ready to just go right into place. Then you have your rear shocks as well, and I'll say that these shocks and struts are better designed for lowered cars and they're also made to complement the Ford racing springs and sway bars. So, we all know that all of these parts work very closely together, so when you start upgrading things like lowering springs and sway bars, you have to keep in mind things like spring rate and sway bar thickness and setup. With an assembled kit like this, you have the comfort in knowing that all of these components are gonna work well together.Moving on to the front and rear sway bars, the performance pack sway bars are thicker in diameter than the non-performance pack sway bars. These are solid steel construction bars, which are a big upgrade over the factory bars, but the downside here is that they do have some weight to them. Like I said before, these bars are designed to work with the progressive springs that are included in the kit. They're not adjustable, so if you're looking for an adjustable sway bar, Ford performance does have a track pack handling kit that'll come with adjustable sway bars. It is different than this kit, but you can always check it out anyways.The last thing we're looking at here are those tow links, and these are gonna help you a little bit with wheel hop and even in the corners. They give some stability to the IRS and help produce some of the unwanted handling characteristics. Now, keep in mind that while all of these components are the major suspension upgrades and they're designed to work together to improve handling, they're not the only components that you can upgrade. There are always other ways to improve upon the S550 platform based off how you like your car to perform, but this is still a good step towards making some changes.Even though these aren't a huge upgrade, we're just upgrading to performance pack specs here, you're gonna expect to eliminate some wheel hop, have less nose dive during hard braking, better cornering ability, and a lower center of gravity for an overall more planted car and having a more stable rear, which allow for harder launches and keeping the suspension more consistent and planted no matter what you're doing with your car.As far as price, this kit is gonna be just south of a thousand dollars. Now, I will say that picking up an assembled kit will save you a few dollars over purchasing each component of the kit individually. You probably could mix brands and piece together your own kit, but you do run the risk of missing out on some ride quality and performance, just from the fact that these pieces are all made to work together. But piecing your own kit is always an option if you don't have the budget for a kit like this. You also have to keep in mind that this exact kit will get you the performance pack upgrade, and this suspension does come from the factory on some cars, so you can expect a perfect fit and highly functional components.So, the install here is a lot of work, but I wouldn't say that it's a difficult install. Like I said earlier, I'm gonna call this one a two out of three wrenches just because you are doing a bit of an overhaul. It's all straightforward and you won't need any tools out of the ordinary, especially since the front springs are already installed on the struts. You just need to get your stock springs out. You'll need an assortment of different sockets and wrenches. And if you decide to tackle this yourself, you can expect to spend about six hours. Having a lift is gonna make things a lot easier here, but you can complete the install with a jack and stands. You'll also have to keep in mind that you'll want to go for an alignment after the install is all completed. You're tweaking pretty much of the suspension here, so it's necessary to get that alignment.So, ultimately, you're going to need to get down to the spring and strut assembly, so everything like the wheels, the brakes, ABS lines will need to be moved out of the way so you can pull the assemblies out of the car. The front spring and strut install is very straightforward. The rear is a little bit different because the IRS sub frame will be dropped, along with the rear shock mount, so you can slide the rear springs out and get your new shocks in. And getting the sway bars and tow links out is really only a few bolts. You might need to pop out your air box to get to some of the bolts for the front sway bar, and the majority of the bolts can be removed from reaching down through the engine bay, except for the unlink [SP] bolts, of course. And the rear is even easier to get to. You can get to all your bolts from below the car. All these parts are reinstalled the same way that the factory ones came out. And like I said, this is a good amount of work to get done but it's not difficult.Wrapping things up here, the Ford Performance Street Handling Pack comes with lowering springs, front and rear shocks and struts, front and rear sway bars, and rear tow links. This kit is gonna upgrade your non-performance pack Mustang and give it the same handling abilities that the performance pack cars have. And as always, I suggest you check this out more online for yourself. For all things Mustang, keep it right here at americanmuscle.com.

Hands over fist, better than factory suspenion
The Front Anti-roll bar, was a huge PITA to install. After that, the rest was a breeze. The ride is day and night better than the factory suspension. No more float braking at highway speeds. And the almost "1 drop, looks quite aggressive.Helpful (1)

Nice stance; improved handling
Enjoy the more aggressive stance, and it definitely tightened things up a bit - even for strict street use.Helpful (2)

Street Handling Pack
Perfect stance but the sway bars are identical to factory. My 2018 GT 301A base model had identical sway bars as what cane in the street handling pack. The dampeners and Springs were an upgrade but had I known I didn't need new sway bars I could have gone in a different direction or selected a different kit. It also cost me probably $200 in labor at my install shop as they completely took out the front sway bar before realizing they were identical. I am giving it a 3 for the stance and ride. The only reason i am not giving it a 2 is that it is reasonably priced so the loss from the redundant parts and poor advertising was mitigated some what.Helpful (19)

So Much Better!
I have a 2017 Mustang GT Premium. I installed the Ford Performance Street Handling Pack. It lowered everything by 1 inch which makes a huge difference in the way it looks and the handling is greatly improved. Previously, the car felt disconnected from the road (like it was floating) at highway speeds. The new suspension feels firm and planted through the corners and under hard acceleration. I was really surprised that the ride does NOT feel harsh at all. The ride is comfortable and controlled. I could not be happier with the suspension upgrade.Helpful (10)

Worth every penny buy it! Here are all my mods: Roush x-pipe: Sounds great and no drone on the highway! Hit the gas, sounds louder than a Shelby GT 350r! I had this installed with the Roush Axel Back, the Street Performance Suspension, and the Ford Performance Pack 1. 6 hour for all and $800 to install all. My Wife raced a GT 350 neck and neck from light to light, gave my wife the thumbs up!Helpful (13)

This is a great bolt on performance product for the daily driver enthusiast that likes to go on weekend drives around those curvy mountain or lake roads, and really enjoy true cornering, and control performance. Good enough to use at any track in my opinion also. Almost zero body roll, reduced squatingdurimg launch, nose dive when braking, fast recovery and hardly any floating feel. Obviously you loose some ride quality but that's the price for enhanced performance. Along with 20 inch weeks and a 30 side wall so no complaints from me just making sure you know if you alter a vehicle period you will no longer be enjoying the factory luxury ride. WE WANT MORE PERFORMANCE. Me and my friend Dan took a proximately 4 hours on a lift to install this kit. I have not had my 5.0 realigned yet. Mainly because I marked both front and back cam dials in two places per cam (there's four) with a grease pen. Lined back up during installation and the car drives perfectly. I recommend any and everyone to install this kit if you like drivin' 50 mph or faster around a corner marked 25 mph with ease an confidence. And don't forget the 275 to 305's for rubber on the rear.Helpful (9)

2017 GT suspension
Great product perfect for those who don't track there car, but want to get rid of the floating feeling the base model GT hasHelpful (9)

After install the car felt great!!!! definitely got rid of a lot of the body roll and floating over bumps but there is a but. After buying and installing I realized the following this is basically just the performance pack you buy from the factory the only difference being -Sway bars front and rear are same size but PP has stiffer bushings you could just buy the bushings -Struts/shocks appear to be the the same except PP has upgraded mounts and lower/stiffer springs and stiffer shocks Rear Toe link - PP has upgraded bushings over stock but you can buy the toe links separate for a little less money you could buy bigger sway bars w/bushings , lowering springs , strut mounts and rear toe links the big benefit of this pack is the struts being already assembled with the springs and mounts something to consider wish I would have known that but I would buy againHelpful (13)

Now it feels like a sports car.
Full disclosure: I also added the Ford Performance Strut Tower Brace and the Steeda Vertical Links at the same time. So, my experience is with the combination of these upgrades. No more body roll. Stays level through launches, stops, and turns. I can feel some bumps in the road a little more than usual, but it's not what I would call harsh. The 2018 GT is no slouch when it comes to acceleration and cornering, but I feel that both are significantly improved now. And some bumpy curves that I normally travel on actually feel better in a way, as though the wheels aren't bouncing all over the place and I have more control. Also, I had a highly rated local shop do the install. It took them 5 hours plus the alignment.Helpful (10)

Better on mountain roads
After driving for one month now with this setup the car handles so much better. It goes where I want it to go and it doesn't hop any more in the curves. It sticks to the road better without compromising the driving comfort.Helpful (9)
Does my 15' GT with PP already have the ford racing springs on it? This video confused me just a little bit when saying " for your non PP mustang... Just wondering if I need springs or this entire setup
This Ford Performance Street Handling Pack are the items that came stock on the pp mustangs, so if you have a pp mustang you already have this kit stock.
Will this package work on GT convertible? It mentions fastback, but the components seem to be interchangeable. If they do not fit, what is the reason?
The reason that these will not fit is that the springs that come with this street pack are rated for the weight of the fastback models. Since the convertibles have a different weight distribution, these will not work correctly if used on a convertible.
What are the specs on these sway bars? So if I have the performance package on my 2017 GT I already have these parts on my car?
The Sway bar's included with the Ford Performance Street Handling Pack has a diameter of 37.00mm for the Front Sway Bar and a diameter of 25.40mm for the Rear Sway Bar.
Will there be any problems with ground clearance over speed bumps and driveways?
Since this has an estimated drop of 1.0", there will not be clearance issues with speed bumps and driveways unless they are an extreme change in the speed bump or driveway.
I have been looking at this suspension kit on several different sites. one thing that other sites offer is the hardware kit (bolt, nuts, etc.). does this suspension kit require the replacement of the hardware or can the original hardware be reused to mount this suspension kit?
The Ford Performance Street Handling Pack would come with all the required hardware that you will need to install this kit on your car.
With it's 1" drop, typically the Ford Performance Street Handling Pack can fit 275/35R20s up front and 315/35R20s out back, however depending on wheel offset, you may experience rubbing. We recommend measuring for clearance due to the large tire sizes you are using.
The Ford Performance Street Handling Pack - Fastback will be able to fit non-performance package Mustang.
All of our model/year appropriate wheel/tire packages will work with this kit, as they are guaranteed to fit up to 2" of lowering.
These sway bars would be slightly better than the 18 base model sway bars.
We generally do recommend a set of caster camber plates to help with alignment after lowering the vehicle.
Unfortunately we do not currently offer a similar kit for the 15-18 GT/EcoBoost convertible models.
Although the kit may physically fit the car we have not tested it on a V-6 application. We can not tell you what to expect on ride height or ride quality.
