Review & Install Video
Hey everybody. I'm Justin with americanmuscle.com and this is my detailed overview of the SR Performance Adjustable Front Sway Bar available for your 2015 and newer Mustang. You should be checking out the SR Performance Adjustable option for your Mustang if you're looking to upgrade your factory front bar with a solid 35 millimeter option preferred to be adjustable so you can dial in the stiffness of the bar itself and finally, you'd like to save a few bucks by going with a value brand or option like SR.
Now the sway bar is just one piece of the suspension puzzle, and honestly they can be a bit confusing if you don't know what you're getting into. Now in a nutshell guys, a sway bar is essentially a spring, and it is going to control the side-to-side or lateral movement of your Mustang, becoming very important in your car's cornering and capabilities. This means it's going to help reduce body role and actually the car rotate through the turn.
Now the school of thought with these newer Mustangs is that they tend to be a little under-barred from the factory, just to maintain more of a neutral feel without a ton of oversteer in factory form. Now, a quick rule of thumb tells us that a larger rear sway bar will help promote oversteer, which is the feeling of the back end coming around or rotating through the turn, while a larger front bar will help promote understeer, basically the car plowing through a turn. The challenge is finding s good balance between the front and rear sway bar and using the adjustment to really fine-tune the understeer or oversteering characteristics or help achieve a neutral balance overall.
So what can you expect when installing the SR Performance Front Sway Bar? Well for starters, it's going to reduce a ton of body roll with your Mustang and that's why you often hear sway bars referred to as anti-roll bars. In addition to that, by adding a bar this large compared to your factory bar, you can expect things to really stiffen up while cornering with your ride.
Adding a bar this big can really help you in initial turn-in during quick steering situations, such as slalom-style courses or even a quick lane change. However, by over-barring the front here, you do run the risk of understeering mid-corner and even corner exit, like I talked about a little earlier. That's why i really suggest when doing a bar like this for the front, you match it with an aftermarket rear bar of your choice, because installing this thing with a stock rear sway bar might result in some understeering characteristics.
With that said, you do have some adjustability here with the SR Performance options, so you can soften or stiffen the bar depending on your driving style, and this is definitely something to keep in mind here, guys. Everybody has their own personal preference when it comes to their driving style. Everybody prefers their car to feel a little differently, so this is one of those things you're going to have to experiment with before landing on your ideal settings. Personally, I would start with your end link in the middle hole and just start experimenting from there. If you wanted to soften the spring rate of the bar, simply move it one notch closest to the rear of the car. But if you wanted to stiffen the rate of the bar, simply move it one notch closer to the front of the car.
The SR Performance Sway Bar is going to offer a pretty sizable upgrade in overall diameter, coming in at 35 mm, and this seems to be the most popular size for the aftermarket front sway bar options, at least here on the site; BMR, Steeda, Eibach, they all seem to share the same 35 mm diameter. The SR Performance Front Sway Bar is made in the USA, from solid cold-formed high strength, aircraft grade steel. It is finished off in a black powder coat just to help reduce any corrosion. They do throw in brand new bushings and brackets. Those bushings are greasable by the way. However, they do not include brand new front end links. It wouldn't be a bad idea to pick up a set of adjustables, especially if your S550 is a little lowered.
On the topic of price, guys, the SR Performance option is living up to its value name. It's going to be the most affordable in the category, falling right in the mid-$200 range.
Moving on to the install, now I will say their front bar is definitely the more difficult of the two, compared to the rear, but overall, still really not all that bad. You will need to attach some bolts from the engine base, so just get your extensions ready, along with being prepared to remove your air box to access those driver's side bracket bolts. Really not too bad here guys, I'll give it a one out of three wrenches on my overall difficulty meter, maybe an hour or two from start to finish, and that's pushing it. I will say the few times I've done a front sway bar on the S550, having a buddy on hand to help you fish the bar through the engine bay has made life a whole lot easier for me personally but overall really isn't that big of a deal.
As for my final thoughts on the SR Performance option, here you go guys: this is going to be a great and affordable way to get most of the performance benefits of a big front sway bar, an adjustable one at that, but it's still going to cost you a little bit less than some of the other options on the site.
