Description

Our Steeda Mustang Rear Sway Bar for 2015+ Mustang GT, EcoBoost, or V6 are track-proven sway bars that will give you reduced body roll, adjustability, and the best handling of any sway bar out on the market.

Our press-fit welded billet ends on our Steeda Mustang Rear Sway Bar for S550 Mustang GT, EcoBoost, or V6 are far stronger than stamping the end of the bar. Billet machining construction of the sway bar ends makes for far greater strength for a bulletproof sway bar.

Don't settle for sway bars that are not track-tested and made by companies who do not specialize in Mustangs. Steeda engineers, races, and wins with what it sells, order the best package for your daily-driven or track-driven Mustang today!

Our sway bars have machined steel billet sway bar ends, whereas others on the market have coined ends. What does this mean? Our sway bar ends are machined out of billet steel round stock, in-house, on our multi-axis CNC lathes and go through hundreds of computer simulations to ensure the ultimate in strength and performance - this provides greater resistance to bending stresses, and has three major advantages:
  1. These parts are less prone to cracking/fatigue failure on the ends themselves.
  2. It also reduces unwanted deflection in the sway bar end. Excess deflection creates unwanted geometry changes, which physically changes your sway bar stiffness to a non-ideal rate.
  3. With less unwanted deflection, our bars will 'wear out' slower - any spring will eventually become softer over time as it is cycled through its life, our bars will maintain their designed rate for longer with less unwanted deflection.

Our bar rates are developed and optimized through advanced vehicle dynamic simulation and through extensive real-world testing. We engineered these bars to control the vehicles' roll stiffness properly while still allowing you to run softer springs. This optimizes your overall grip and balance of the vehicle while still allowing you to maintain exceptional ride quality.

Hi everybody Brian from Steeda.com. Here today to show you our adjustable rear sway bar for the S550 Mustang. The rear sway bar functions just like the front sway bar and posted a video about the front sway bar just a few weeks ago. You can check it out here if you haven't already. So you're going down the road the nice thing about the sway bars is they don't affect the ride quality. When you go into a corner and the car wants to lean or roll toward one side or the other side, the sway bar works against the opposite spring. This is what helps keep the car flatter. Now one of the nice things about choosing between the front and the rear sway bar is setting up the balance of the car the way that you want it. Whether you're an enthusiast and autocross racer a track-day junkie or a full-on competitive racer, this is a great way to set up the back of the car. Now with regards to the balance just like the front bar, the rear bar is adjustable. So you're able to do is if the cars inhibiting understeer and you want a little bit more rotation you can come to the stiffer position now the stiffer position is a 138 percent stiffer than the performance pack rear sway bar. Likewise, if the car is too tail-happy and you need to tone it down you're going to go to the softer setting or the furthest out setting and that's 54 percent stiffer than the performance pack sway bar. Our rear sway bar is an inch and an eighth in diameter and it's tubular larger diameter so we could have more effective rate out of it and stiffer versus the factory bar and also have it be lighter weight. Now of course we always take things a step further if not a few steps further. We have centering collars to make sure that under any types of hard loads, cornering, autocross sessions, track days or how whatever you throw out the car that the sway bar is going to stay centered underneath it and do what it needs to do. Now to go even further with this we cnc cut billet steel ends and then radius weld them to the sway bar. This is going to be the strongest connection on any sway bar you're going to find anywhere and we finish off the sway bar by powder coating for corrosion resistance. Also all the hardware needed to mount the sway bar is included for simple installation. The sway bar is covered by our lifetime warranty and we proudly manufacture this in the USA at our Valdosta, Georgia facility. If you're looking to improve the handling capabilities and/or balance of your Mustang this is a must-have. If you have any questions or comments please post them below.

car should drive like this out of the factory!
I spend Sunday installing Steeda's front and rear sway bars (with billet aluminum sway bar bushings) on my 2015 GT PP. This is in addition to the progressive springs and sub frame bushing supports that are already installed. The installation of the rear parts were easy while the front was more tedious but not impossible for the average mechanically inclined person. I opted for maximum stiffness on the sway bars for the best handling performance. visibly there is a huge difference in the side and quality of the sway bars. Steeda's are much more stout and the bushing are significantly stiffer, the mounts are lighter (based on the standard mounts that come with the sway bars) but a much better design. The sub frame braces look like the perfect way to tie the IRS sub frame into the vehicle and "tighten things up". The brace connects near the jack points on each side to two points on the sub frame and one point in between creating a triangle for some serious stability. This is a tight fit so make sure you follow the instructions from Steeda and keep the bolts loose until things are set. I haven't had the car on the track yet, but there is a huge difference in just daily driving. I've hit a couple of curves hard and the car seems to dive into them and there is much more confidence in the car. I hit a pretty sharp curve the last 2 days on my way to work and I don't feel any understeer at all (at least I can't tell) I was doing between 60-70 mph through the turn it just felt nice! All in all I made a great choice. Steeda should have sold these to ford during manufacturing and the car should drive like this out of the factory!

The car feels very nimble and netural
Ok so after a couple days of driving and finally getting some spirited driving in today I think the sway bars made a significant improvement in handling. The car feels very nimble and neutral compared to before. I went with the middle hole in the rear and the 2nd stiffest setting up front. Would recommend this to anyone looking to feel more contacted to the car in the corners.

One of the biggest improvements to the handling of the car
One of the biggest improvements to the handling of the car is definitely the Steeda goodies all thanks to David here on the forum. He helped me so much picking out everything I should upgrade for all of the suspension parts to make this a great daily driver but also be able to take turns comfortably at high speeds and put the power to the ground. One of the first Steeda upgrades Slammered threw on for me was the Front/Rear Sway Bars and the IRS Support Brace and damn did it make a pretty damn noticeable difference in turning. No I don't track this car as of right now but the closest I get to taking turns and curves is off ramps from the highways and I've done decent speeds coming through those turns. The sway bars help keep the car planted and definitely boost the handling capability that the IRS already provides. I also installed the billet mounts and they look damn good with the blue sway bars and definitely are top notch quality over the stock mounts from Ford. Wheel hop has been one of the most notorious things the S550 platform has encountered with the new IRS system. Wheel hop is a "No no" and Steeda's IRS bushings are definitely the first step to knock out way more than 50% of the notorious wheel hop. When taking the bushing out of the box and taking a peek at my new goodies, I was amazed of the quality that is put into the manufacturing of the parts Steeda offers. IRS Bushing from Steeda is a must if you're looking to eliminate more the 50% of the wheel hop. It's great quality and definitely helps put the power to ground. When hitting it and shifting from 2nd to 3rd it's a whole new feel and it just takes off.

It's a HUGE differnce from the relatively vague/floaty stock PP setup
The G-Trac brace made a big difference in ability to turn in with exactitude on my PP-equipped GT, albeit modified with Steeda springs and sways. The back end of my car got where I needed it with Steeda springs, sways, bushing mounts and vertical links. The car now steers beautifully, doesn't roll, doesn't pitch on acceleration or dive under braking, and the front-to-rear grip is matched, yielding great confidence to place the car right where you want it on corner entry, mid turn, and exit. The G-Trac brace's effect on steering was both noticeable and transformative. It's a HUGE difference from the relatively vague/floaty stock PP setup. I'd say it even rides better without those stock PP undulations. I did not feel the need for the rear brace after the bushing mounts and vertical links (put on after everything else), but that's not to say that the chassis wouldn't improve yet more from it; I'm still considering doing it. It's just that the car feels perfect right now for hard-ass canyon carving and everyday use.

The ride is amazing, to be honest
The car sits perfect with these springs. The ride is amazing, to be honest. The nose dive on braking has been reduced great,y. The car is very flat when cornering and just begs to be pushed more and more. One thing that seems to have greatly improved is the response of the initial turn in. It is very, very responsive. I assume it's a combo of the springs and sway bars but not sure which contributes more to it? I set the front sway bar on the 3rd setting, one away from the firmest and the rear one is set on 2, one away from the firmest.

I'm officially a believer!
Ok. So I know everyone has already made threads about their Steeda stuff, but I'm officially a believer! Springs Sway bars Sway bar Billet Brackets Vertical Links Toe Arms Bump steer kit G-Track Brace IRS bushings MMR Camber Plates Performance wheel alignment The car is a go kart. Set the front sway bars to the center and rear to the lower settings, entry high speed turn is predictible, so much so I haven't learned the limits yet. The ass can be easily manuvered with throttle (Race mode/traction off). The body roll seems like it's gone (once the track wheels/tires come in I'll know for sure), it's unreal, I am in LOVE with the car now. This is the way it should've come from the factory for the PP cars. Really a learning curve, since now everything is souch more compossed. The IRS bushings and arms drastically changed the feel of the car on take off, the power actually goes to the tires (which I spin even easier now, even with camber still within factory specs.) There's not that feeling like the IRS wasn't properly fastened, it feels like it's built in to the body. Such a great mod. I'm ordering the IRS brackets as well, but I don't see how it can really improve further. It that good!! Steeda has my vote!

What a major difference
Added the rear Steeda sway bar and iRS support brace. Also ordered the Steeda rear billet mounts for the sway bar. What a major difference these two made to the ride and stiffness. Feels like a new car (for the better). Feels a lot more solid.
