      Hey guys. Stephanie with americanmuscle.com here with Eibach Anti-Roll Sway Bar Kit for 2015 and up S550 Mustangs. The Eibach Anti-roll sway bar kit is gonna be a good option for someone that's looking to gain some handling performance for the S550 at a competitive price when compared to other brands. Sway bars in general tend to be on the most cost effective handling upgrades. They provide a lot of benefits such as less body roll for better all-round handling which is great news for the S550 chassis and they aren't as expensive as all the suspension mods. The easiest way for me to explain how a sway bar works is to imagine a car that's taking a corner. As a car is cornering, the weight of the car is pushed outwards towards the outer tires. This weight compresses the suspension on the outside of the car and decompresses the suspension on the inside. The sway bar counteracts the compression and the decompression. The weight transfer creates a twisting force in the sway bar so the sway bar creates a lifting force on the outside control arm. So the sway bar creates a flatter handling experience. There are a few things that affect how much force the sway bar has or how effective it's going to be. The thickness of the bar and its composition are gonna play a big role and these bars from Eibach are tubular which is nice because you get the strength like you would with a solid bar but without the weight. This is aircraft grade tubular steel and it has been cold formed. The front bar is 35 millimeters and the rear bar is 25 millimeters which are big upgrades over the factory bars. These are also powder coated rods, they're going to have corrosion resistance as well. Another factor that's going to affect how well a sway bar works is the geometry of the bar. So sway bar has bends in different angles but the key is gonna be the length of the lever arm. This is the lever arm right here. Both of these bars are three way adjustable. You can see your adjustment points right here. Having these bars three-way adjustable means that you have a longer lever arm. Depending on how you adjust the bar and install it, you're changing the geometry of the bar. The shorter the lever arm is, the greater torque and more force the bar will have. So this is what you're adjusting when you're moving between these holes here. The amount of force and torque that will be applied to that outside control arm in order to decompress the outside suspension. Bushings are also going to affect the sway bar. Now, these bars come with polyurethane bushings which is going to be a good option for a street car. Poly bushings are more rigid than the factory soft rubber bushings are but they aren't too rigid to stop all movement. The more rigid the bushings are, the more rigid the bars will be because they will not be allowed to move as much. The softer the bushings are, the more movement the bar will have and the less effective it will be.The last thing that I wanted to talk about when it comes to sway bar effectiveness is that suspension travel is going to affect the sway bar. And when I say suspension travel, I'm mostly referring to spring rates. The sway bars and the springs are gonna work very closely together like all suspension parts do. Spring rates are gonna change the amount of compression or decompression that occurs within the suspension, so of course these two components are gonna work hand in hand. So just remember that when you're shopping for springs or if you already have springs. The basic rule of thumb is that sway bar thickness should increase as static spring rates increase and vice versa. When it comes to fitment, these sway bars are gonna work on all 2015 and up Mustangs including coupes and convertibles, GTs, V6s and EcoBoost models as well. As far as price, you're looking at spending between $400 to $500 for this kit which is relatively close to other options on this site that include Ford Racine and BMR. The other options on the site do have different materials or different adjustability or different thicknesses. So just make sure you're shopping in the range of materials, thickness and adjustability that you need for your set up and how you want your car to perform. The install for this sway bar is not difficult at all but you're looking at two hours to get it all done and a one out of three wrenches on the difficulty meter. You need a handful of different tools but nothing crazy and as usual a lift would really help here but the job can be done on jack stands if you don't have access to one. Your old sway bars are gonna need to be removed but this is just a few bolts. And I would recommend greasing any new bushings really well prior to the install since waiting until after everything is installed will make that process much more difficult. And grease the bushings as much as possible since poly bushings can be a little noisy after a short period of time. Getting the factory sway bars out is really going to need 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 endling bolts of course. Then you just have to maneuver the old bar out, which can be a little tricky, but it just takes a little time. The rear bar is a little bit easier to get to. You can get to all the bolts from below the car. You just remove the endlings and the bolts and the brackets that hold the bar to the sub-frame and sneak the bar out from below the car. The new bars install the same way the old bars came out so there's no surprises there. You just need to figure out your adjustment points and how you want your car setup. Wrapping things up here, the SR performance sway bar kit includes a front adjustable bar and a rear adjustable bar that are tubular in design and thicker in diameter than the factory bars for more rigidity. This gets made to help with cornering handling by keeping the suspension flat and even. And you can check it out more online right here at americanmuscle.com
