      Video Review & Installation

      The SR Performance adjustable rear sway bar is available for any 2015 or newer Mustang owner who might be looking to pick up a noticeable change for their suspension in order to improve handling around corners. Especially, while being able to fine-tune the stiffness or looseness using the adjustable arms. This is a very durable construction at a very affordable price, at just south of the $200 mark. Now, the installation, very straightforward stuff, will be a direct bolt-on swap from your factory sway bar. I give it a one out of three wrenches on our difficulty meter, but we'll talk more about that later on. Now, if you're not too familiar with what exactly a sway bar is or does, let me break it down for you in a nutshell. So this will help with side-to-side movement of your Mustang, but especially come into play around tight corners. It's main function is to reduce body roll, which is why you might also hear it referred to as an "anti-roll bar." It'll also help maintain stability, rotating throughout the turn. The factory sway bar does stay pretty neutral. So if you pick up a larger rear option, such as this one, it'll help to promote over-steer, basically the rear end rotating through the turn. Whereas, the other hand, or the front sway bar, if you picked up a larger option, it'll help to promote under-steer, which is going to cause the car to kind of just plow through the turn. It obviously comes down to personal preference. But most people want to find a happy medium or a perfect balance between the two. So it's usually a good idea to pair up a front sway bar with a rear, if you go with aftermarket options. Keeping a flatter ride is going to happen no matter which one you pick. So this is even great for the guys doing a lot of daily driving, because it will make a noticeable difference, even with a quick lane change. Since this is adjustable, it will allow you to fine-tune exactly how you make it feel on your car. So with the three holes on each end of the bar you see on the arms here, it'll allow you to adjust between the stiffest position, the loosest, and then obviously a more neutral feel. Neutral is still going to make a difference over stock. Remember, the bigger the bar, the stiffer the suspension is going to be. This is a more budget-friendly option, so one of the more premiums like BMR will make an even bigger difference, but this will still make the difference nonetheless. Speaking of which, this is a 25-millimeter diameter, solid cold-formed, high-strength, aircraft-grade steel, very durable stuff, which is exactly what you want, because it will be under so much pressure on your suspension. It's completed with a black powder-coated finish, which gives a more stealthy appearance, but more importantly, it gives it a rust and corrosion resistance. It also includes what you don't see on the table with me today, a set of polyurethane bushings, which are going to be more rigid than the factory rubber options, which will just make sure even more that it stays in place and prevents as much movement as possible. Just about $200 gets you this sway bar here, which in my opinion is a very affordable price tag, since it is a very worthwhile part for your suspension. It makes a huge difference, even on the street, and you will immediately feel that difference. With that said, if you're not really interested in the adjustable option, maybe you just want a quick replacement and want to save a few bucks, the nonadjustable option of exactly this is available. But I do recommend adjustable for the guys looking to more personalize the experience, and kind of go through the stiffer and looser options for different ways of driving. Now, if you've never tackled a sway bar install job before, I want to point out, very direct bolt-on install. Not much really involved in the process. Expect one out of three wrenches on our difficulty meter here. You can have it done in probably about an hour at the most. I would say a ratchet and socket set will do the trick, as well as a set of jack and jack stands, or a lift if you have access to one. As you can see on our 2015 GT here, our guys in the shop started off by getting the Mustang in the air, and removing the 10-millimeter bolts holding the brake line bracket to the sway bar end link bracket. Next, the bolts holding the sway bar to the sway bar end link come off, and then the bolts holding the bracket to the frame. Install the poly bushings over the ends of the bar, and then of course the brackets over the bushings. From here, install the SR Performance bar into the factory locations and use the factory bolts. From here, you can actually make the adjustments. Remember, the hole closest to the rear of the car will soften the feel. Closest to the front of the car will tighten the feel. The middle is neutral. The middle is where I'd recommend starting off, again, just so you can obviously gauge exactly how the feel is, and then make your decision from there on how you want to set it. That just about does it for me. So if you're the owner of a 2015 or newer Mustang GT, you might want to check out the SR Performance adjustable rear sway bar, available right here at americanmuscle.com.
