Review & Installation Video

Review & Install Video

Hey guys, Stephanie with americanmuscle.com, here with my review and an install of the Roush Triple Adjustable Coil Over Kit, available for all 2015 and newer S550 Mustangs. In this video, we're gonna go over a few different topics with this coil over kit, but mostly we're gonna talk about the performance abilities of the kit and the install. Gonna cover the install in more detail later, but I'll tell you right now that this install is straightforward but it is a little bit of work, so I'm gonna call it a two outta three wrenches in the difficulty meter. The Roush Triple Adjustable Coil Overs are gonna be for the Mustang owners out there that are looking to get away from the fixed drop of a lowering spring, and for someone that's looking for a kit that's gonna give them the most adjustability. A set of coilers like this are gonna totally transform the handling of the S550. Typically, a lowering spring is gonna best for someone that's looking for someone to simply lower their car, and that doesn't really mind a stiffer ride. The spring rate in a lowering spring is not gonna be as aggressive as in a coil over because they're mostly designed to be used with stock shocks. Coil overs like these on the other hand, come with shocks and struts that are set to take the abuse of a lowered car, and these are gonna be designed to work with the coil over spring rates. So if we jump right into this, we're gonna be talking about the height adjustability that this kit offers, which I think is one of the biggest pluses when choosing a coil over setup as opposed to the traditional aftermarket static spring setup. You're gonna see that these coil overs offer a fully customizable range of height adjustment. This kit offers a drop in the front of the car that ranges from .8 to one and a half inches, and one to two inches in the rear. This means that you can set your ride height anywhere in this range, depending on what you're looking for. I will say that this isn't the lowest that you can get on an S550 with a set of coil overs, but these coil overs also offer some other features that others don't offer. Roush calls this kit triple-adjustable because they give you three points of adjustment. Not only can you adjust the right height, but you can also adjust rebound and compression on the shocks and struts. Roush has another coil over kit that they call single-adjustable because you can only adjust ride [SP] height on that kit. The compression and rebound are already pre-set for you. And having these three points of adjustability in this kit isn't something that all coil overs have, just the more advanced offerings. Having these points of adjustment means that you're gonna be able to really fine tune your handling. So the kit is gonna include two front strut assemblies, two rear shocks, two rear springs, and your spanner wrenches. Your spanner wrenches are gonna be your way to adjust your coil over height, which you can see your threads right here on the actual strut body. Now, this is superior to your other type of coil over where you literally need a turn spring perch in order to compress the spring against the top hat, in order to change the ride height. The problem with this is that it puts preload on the springs and then you're already setting yourself up to lose some handling performance. So this is a better design because you're actually expanding or compressing the coil over itself. This isn't gonna change the compression of the spring and it's a better way to adjust height. Getting into some more specifics about the construction here, other than the fully-threaded body, you're looking at stainless steel. The springs are progressive rate springs which'll be nice for the street, and the springs are designed for the abuse of coil over. Now of course, these do have that factory style bracket which makes these a direct bolt-on. When we start to look at price, you're gonna notice that this kit is one of the most expensive options when you look at coil overs. This is because of the extra adjustability that the kit offers, and of course, the branding as well. Has a price tag between $2,000 and $3,000, which is the second most expensive kit that's available. If you look at another kit that offers only height adjustment and not dampening adjustment, you're looking at spending closer to the $1,500 or $2,000 mark instead, just so you guys have an idea. This is a bolt-on kit, guys, and it'll work for both coupe and convertible models. There's no permanent modification necessary but there is a fair amount of work involved with the install, it's a few hours or so, so I'll call this a two outta three wrenches on our scale when we look at overall difficulty. The work is straightforward and ultimately you're gonna need a decent socket set, a jack and stands, or a lift to get the job done. You have to break down everything like your calipers and rotors, and get to your old shock, and strut, and spring setup, though. And you've gotta get your new setup in, and then don't forget you might need a little extra time to get the right height dialed into your liking, and the dampening adjustment as well. You may end up having to do a few adjustments to get your car to be where you want it to be, and then you have to make sure it's even on each side. You are gonna wanna make sure that you're setting it up for whatever you plan on doing with your car, or for the performance that you want out of it, whether it be the dragstrip, a cornering beast, or just a low car in general. And keep in mind that after tweaking this much of your car's suspension and ride height, you're probably gonna need a good alignment to make sure everything is in spec. So overall, the Roush Triple Adjustable Coil Over Kit is a high-quality kit that's gonna offer a lot of room to adjust ride height, and compression and dampening as well. Its design means adjustment on the strut tubes themselves, which is superior to other methods and offers a wide range of adjustment. But as always, don't just take my word for it, especially when it comes to something of this nature. I always encourage you to check it out more online for yourself and to look at your other options out there. I'm Stephanie, and for all things Mustang, keep it right here at americanmuscle.com.

Would these be helpful in eliminating wheel hop, or should I still look into getting other products as well to eliminate wheel hop? (Going supercharged next year, and don't feel like wheel hopping under boost)

Isaiah

  • The Roush Triple Adjustable Coil Over Kit will prevent some wheel hop, however the bigger reductions in wheel hop will come from stiffer bushings in the rear to prevent any axle windup.

If installing this kit, would it also be a good idea to install caster/camber plates to facilitate proper alignment? I would also like advise on the IRS. Particularly, should adjustable IRS components be installed as well and which pieces would give the best adjustability for road and track use?

    Roush Triple Adjustable Coil Over Kit

    I installed these on a 2015 Mustang GT that already had the Ford Performance Track Package on it. With the Roush triple adjustable components installed, a very noticeable improvement has occurred. The car feels more responsive, more nimble. It feels simpler feels lighter through turns. I knew that lowering unsprung would help, but I was not aware the improvement could be so significant. I am setting the car up for track-day use.
