Good bar, but...
I installed this bar a few hours ago and it seems like it’s been doing very well. The size of it really doesn’t look much bigger than the stock one but it is a little thicker. My only complaint really, is about the grease they give you for the bushings. It is EXTREMELY sticky so be VERY careful where you get it. I used my fingers to kind of spread the grease in the bushings thinking it would be like normal grease. I quickly found out it is the closest thing to tree sap than I have ever seen and I have been scrubbing my hands with a sponge, rubbing alcohol, dish soap, and anything else I can think of for the past hour. My hands are still sticky and grippy from it so we shall see. Good bar though.

Fantastic sway bar for the ST
This bar both stiffens up the rear of the car and adds further balance and predictability to a great platform. I regularly autocross my 15 ST and with this bar have taken top 5 PAX (with 1 1st place) in every event I have entered. Makes the car extremely predictable with the lift off oversteer we love on these cars. I also added the Steeda rear endlinks at the same time so I'm sure they also helped to eliminate bind in the upper mounts and the adjustability is great.

This should be your first mod!
Installing this rear sway bar completely changed the way this car handles. Install was easy and the instructions were well written. I took the ST to Tail of the Dragon after installing the rear sway bar and WOW! I loved the way the car handled. Just coupled this rear sway bar with Steeda's lowering springs and now the car really handles amazing. Make it happen!

Love it!
I purchased and installed this the first week in July. Probably the best money you can spend to improve handling. The car now corners like it is on rails. The suspension and tires are stock and the improvement is very noticeable and predictable. The install took a casual 30 minutes. Thanks Steeda

Must buy!!!
I installed mine yesterday morning in the parking lot of the Oskaloosa Municipal Airport right before an autocross event. Easy install! Have a retap kit handy just incase. Ford uses red bolt lock to secure the bolts and they do not come out easy and they leave a mess behind when they finally do come out. Everything took around 1.5 hours to install (removal of stock sway bar and installation of Steeda bar). One mistake I made: I did not put enough grease in the bushings. Sounds like the rear suspension is falling apart. That's my own mistake though. The product quality is amazing and the performance difference is very noticeable. It doesn't necessarily over steer more than it did before but the over steer is much more controlled and easier to feel when it is going to do so. Body roll seems to be reduced quite a bit as well! AMAZING PRODUCT! Well worth the money!!!!

Highly recommend!
The car handled great stock but with this bar installed it is literally glued to the road. This is the wife's car so all mods have to be done on the gentle side. Took her for a test drive and told her to hang on as I wast cutting on the vacuum and taking some curves. The car stuck like it was being sucked to the road. After about 2 minutes she stopped screaming and I slowed down as she said she was going to be sick. If you want a thrill ride this is the car for it and this bar will add new meaning to going to the amusement park. Install was straight forward and just as the directions stated. I had access to a lift so it made it a non event. This is one screaming machine!

Coming from my 2005 Saleen Focus the only thing lacking with the ST was the suspension. Don't get me wrong, its nice and all but just didnt handle like the saleen did. First was a set of lowering springs, that helped immensely but didnt solve the body roll in the corners. I am happy to say that this swaybar fixed the corner slop!! Great fit and finish, fairly easy install, and fantastic performance! So much more planted in the corners and it helps inspire more confidence taking corners at speed. Great job Steeda

BLUF: Handling improved tremendously. Don't think about it, do it! Changing out the OEM SB with Steeda's SB was like adding giant magnets to the rear of the car. Very easy install in less than 40 minutes. The PU bushings are a nice added plus. Packaging, item quality, instructions, and fitment are all outstanding as usual.

This is a perfect fit and great quality. I didn't think my focus could handle much better, but this is a big difference!

Huge improvement!
Much tighter into turns. Huge improvement, but highly recommend coupling it with the lowering about night and day improvement!

2013 Focus ST rear Swaybar = Awesome!
It's amazing how well my ST corners now. I thought it was on rails before, but WOW! If you're into a better overall driving experience and want to virtually eliminate the body roll, this modification is perfect. The install was super easy and I was driving within 1/2 hour. I removed the wheels for a little easier access, but it's not necessary.

What a difference in handling!
I just received my rear swaybar for my 2013 Focus ST and when I took it for a test drive, I immediately noticed much less body roll going around curves. I will be testing this out during my next autocross and I'm sure that it's going to make a very nice difference. Great product!

A Must Have!!
The Mountain Run Testing. Once getting on it in the turns, I could instantly feel a difference. The body roll in the rear was all but gone and the car had a more stable feel. The biggest change was that the amount of understeer and oversteer seemed to be perfectly balanced, neutral if you will. While accelerating in larger swooping turns, the understeer that I experienced before was jsut about gone. Instead, the car would slowly float outward in a very easy to control manner. The rate of outward slide was very predictable and eventually I was able to adjust my driving for it in a very short period of time. In the areas where the steering wheel was turned left to right and left right, I thought that the suspension would eventually give and the back would slide out a bit behind me... NOPE :-) If anything, now it feels like the front end is having to do a lot more work and can sometimes be on the line of being overtasked with the accelerating, the braking, and the turning, and the push from the rear, but that's where Ford shined in my opinion. The front end while feeling over tasked did everything I wanted it to and probably could have done more. In the real technical areas, I was able to pull away from the ST behind me, but that could just be a difference in driving skill. Final Opinion: Ford gets 10 thumbs up from me for hitting it out of the park with the ST, I couldn't be happier with it. Steeda gets another two thumbs up for creating a high quality product that doesn't change day-to-day drive-ability, but noticeably increases the handling capabilities in aggressive driving situations. Incredibly easy install, a great price, I recommend it to anyone that plans on driving it at any point beyond the normal daily commute.
