Review & Installation Video

Review & Install Video

Hey, guys. Stephanie with americanmuscle.com here with my review and an install of the Pedders Extreme XA Coilover Kit available for all 2015 and newer S550 Mustangs. In this video we're gonna go over a few different topics for this coilover kit, but mostly we're gonna talk about the performance abilities of this 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 out of three wrenches on the difficulty meter. Pedders Extreme coilovers are going to 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 height adjustability benefits and a kit that's gonna totally transform the handling of the S550 instead. Typically, a lowering spring is gonna be best for someone that's looking to simply lower their car and that doesn't really mind a stiffer ride. The spring rate and the lowering spring is not going to be as aggressive as in a coilover because they're mostly designed to be used with stock shocks. Coilovers like these on the other hand come with shocks that are set to take the abuse of a lowered car, and these are gonna be designed to work with the coilover spring rates. If we wanna just get right into this right away, we're going to be talking about the height adjustability that this kit offers, which I think is one of the biggest pluses when choosing a coilover setup as opposed to a traditional aftermarket static spring setup. We're gonna see that this kit offers anywhere from the stock ride height to a two and a half inch drop. This means it can go anywhere from just below stock height to tucking wheel height and anywhere in between depending on what you're looking for here. And we know from lowering springs for the S550 that a 2.5 inch drop on an S550 is significant. So you have a lot of room here to get your ride height how you'd like it. This kit is going to include two front strut assemblies, two rear shocks, two rear springs, and your spanner wrenches. You don't get new dust boots because you can see that the dust boot is integrated into the body here. And the spanner wrenches are gonna be your way to adjust the coilover height which you can seat your threads right here in the actual strut body. Now, this is superior to the other type of coilover where you literally need to turn a spring perch to compress the spring against the top hat in order to change ride height. The problem with this is that it puts pre-load on the springs and you're already setting yourself up to lose some handling performance. So this right here is a better design because you're actually expanding or compressing the length of the coilover itself. This isn't gonna change the compression of the spring and it's a better way to adjust height. Getting into some more of the specifics about the construction here. Other than the fully integrated monotube body and integrated dust boot, you're also looking at alloy steel Motorsport springs which are designed for the abuse of the coilover, aluminum spring seats and lower mounts, and of course, a factory style bracket which makes this a direct bolt-on replacement. Another big feature of these coilovers is that they are 30-way adjustable which means that you have 30 positions of adjustment between bump and rebound dampening, which is the compression rebound of the shock and strut. This is going to allow you to stiffen or soften the shocks and strut which means that you have a whole other level of adjustment and customization here. You're really gonna be able to set your car up for the performance that you want out of it. These having such a large range of height adjustment and dampening adjustment puts this kit towards the top of the line when you look at your other options that are out there right now. This kit gives you more performance than a kit with height adjustment only. 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, a few hours or so. So I'll call this a two out of three wrenches on our scale when we look at overall difficulty. The work is straightforward, and ultimately you're going to need a decent socket set, a jack and stands or a lift to get the job done. And again, it's nothing too hard but just a little time consuming. You have to break down everything like your calipers and rotors and get your old shock and strut and spring setup out. Then, you've got to get your new setup in, and then don't forget you might need a little extra time to get the ride height dialed in to your looking 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're 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 drag strip, a cornering beast, or just a low rider 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 looks good and still in spec. All right, so overall the Pedders Extreme Coilover Kit is a high-quality kit that's gonna offer a lot of room to adjust ride height and dampening as well. Its design means adjustment on the strut tubes themselves which is superior to other methods, and it offers a wide range of adjustment from stock height all the way to two and a half inches lower. But as always, don't just take my word for it especially when it comes to something of this nature. I'll always encourage you guys to check it out more online for yourself and look at your other options that are out there. I'm Stephanie and for all things Mustang keep it right here at americanmuscle.com.

Track Inspired Handling. Are you looking to add the handling performance of a track car to your S550 Mustang? If you answered yes, you should replace your original factory shocks and struts with a Pedders Extreme XA Coil Over Kit. Designed to lower your Mustangs center of gravity, these Extreme XA Coil Overs will reduce body roll for flatter cornering and superior control.

Height Adjustable. Pedders Extreme XA Coil Overs were designed to be height adjustable. Featuring a high grade steel lower mount these Coil Overs can be adjusted independently of one another to suite your personal taste. You can lower all four corners for a flat level appearance or raise the rear slightly for a classic raked look, the choice is entirely up to you.

Adjustable Bump and Rebound. Pedders engineered their Coil Overs to be 30 position adjustable, which allows for adjustment of both bump and rebound. You can increase the stiffness of your Coil Overs for a punishing day at the track, then soften them for a comfortable ride home. Pedders Extreme XA Coil Overs are perfect for Mustangs that pull double duty as a daily commuter and a weekend warrior.

Quality Construction. Pedders Extreme XA Coil Overs are manufactured using a gas pressurized mono-tube design with alloy steel motorsport coil springs and high grade aluminum spring seats for enduring strength and durability. To prevent contaminants from entering the shafts and seals, these Coil Overs feature integrated dust boots. Factory style mounting brackets ensure that these Coil Overs will be a direct OEM style fit.

Application. This Pedders Extreme XA Coil Over Kit is specifically designed for use on 2015 to 2017 Fastback and Convertible Mustangs, including the V6, EcoBoost, GT and Shelby GT350 models.

Hi, Im planning to lower my car about 1.5 inch on the front and rear. Would front and rear camber plates/brackets needed to get proper alignment with this kit? If so which product would you recommend?

JohnA

  • Yes, with this kit here going that low would require the use of caster camber plates to get a proper alignment. Any of the caster camber plates we have on the website can be good options with this, however, I usually recommend going with the maximum motorsports caster camber plates with coil overs item number 389059. https://www.americanmuscle.com/mm-caster-camber-plates-2015.html

Are front and rear camber plates/brackets needed to get proper alignment with it set at a lower height?

Andy

  • Since the height is adjustable with these Pedders Extreme XA Coilover Kit, it would be difficult to say if caster/camber plates would be needed. Depending on how much the vehicle is lowered, and if there are any additional suspension modifications, the use of those plates may or may not be necessary. If the vehicle is stock, caster/camber plates are typically only needed for drops in ride height which are greater than 1.5 inch drops in order to retain factory alignment specifications.

Where do you adjust the dampening on these coil overs?

Silentmodz

  • There should be a dampening adjustment knob on top of the front struts which you can turn clockwise to Stiffen the ride or counter clockwise to loosen the ride.

So no spring compressor needed to install this kit?

AndrewE

  • Hello! With a coilover kit, a spring compressor is not needed. This is because you are removing the whole suspension assembly as one, and installing the coilovers in its place

    Big Improvement

    I've been driving with the Pedders Extreme XA for 2 months now and I'm pleased with how the kit is performing. I dropped the car just under an inch front and rear and I think it looks good. The install took me 4 hours by myself in the driveway on jack stands. I spent 2 of those hours getting the ride height correct, and adjusting the rear shock length to match. It rides much more firm than stock (non-performance pack anyway) the way I have it set up (10 from full firm). It's never jarring though and while the smaller road imperfections are more noticeable, the large impacts are much better controlled especially at higher speeds. I dinged it a star for fit because I wasn't able to get the front camber in spec, and one for bang for your buck because I haven't figured out if any of the camber/caster plates are compatible.

    Best Value for Quality!

    These are amazingly easy to install and completely change the feel of the car! With all of the adjustment capabilities, your options are endless. These perform just as good if not better than my last coilovers that were over $2,500. Get them, you won’t be disappointed.
