Flat cornering
This rear sway bar (coupled with the end links) made a huge difference with cornering. I’m running a few suspension upgrades but the benefits were seriously noticeable once this sway bar was installed. I’m a lot more confident going into corners aggressively and the car’s body roll is seriously reduced. Cheap upgrade with a great payoff. Probably one of my favorite mods for the price. Install was easy. Straight forward. Just remember to install the right way. Pay attention to how the stock bar comes out and compare it to the Steeda bar. Then install the same way. No flippy around. Flippy bad.

I am using Option Lab R716 18x8.5 wheels and the shop had to cut the end hole off to prevent contact.This part combined with Steeda's billet aluminum sway bar mounts has stiifened up the rear-end quite nicely.

Great performance - odd fitment?
As always, Steeda shipped fast with no payment drama or weirdness. Product was packaged appropriately. On the stiffest setting, I find it's much harder to induce understeer with assists off while taking a turn at high speed with no foot on the gas. Instead, when the car is about to break traction not under power, the outside wheels lose traction in very tiny amounts well before fully breaking. The car is more communicative about impending traction loss without sliding off the line you've chosen. In other words, the range of speeds in which you have less than 100% traction, but more than understeer, is larger than on the stock bar.It's also noticeably harder to induce understeer mid-turn by applying the gas. In addition, when it does understeer under power, it's predictably easy to induce lift-off oversteer that points the car in the direction the wheels are aiming. This is good if you make a mistake when applying the gas coming out of a turn.Per usual, Steeda's instructions were...not optimal. They only have instructions for installing their non-adjustable sway bar, which is fine except that nowhere in the box or on this site does it say which hole is stiffest. I know enough physics to guess it's the one farthest from the ends, but c'mon.Took it to a suspension shop. I have Motegi MR140s 18x8.5 on my Focus. At least with those wheels, the bar wouldn't fit. The shop had to cut off the bar ends around the middle hole (another reviewer noted the same problem). In that sense, this bar is NOT adjustable. I know that the stock Focus wheels are 18x8, so I guess that additional half inch could have caused this problem, but the sway bar product description only specifies wheel diameter, not wheel width.

Stiffness With Some Adjustment
This sway bar has definitely helped in the corners. I can take sharper turns harder and faster. The only issue that I ran into was fitment. The product description says you must have an 18 in wheel and the stock wheels at 18s so I didn't think anything of it. Come install my buddy and I got the bar on and were ready to put the wheels back on and the end of the bar was touching the inside wall of the wheel without the wheel being fully bolted back on. Our solution was taking a hack saw through the center of the furthest link point which created more than enough space between the bar and the wheel wall. Not sure it that is just a thing with the way the stock wheels are but definitely something to be aware of.

Great upgrade from stock
The ST is a great handling car from the factory, but this sway bar makes it even better. Great upgrade at a good price, and love the fact that it is adjustable...Love the color also.

Great piece with adjustability
I initially installed this with the endlinks in the outside position. That was very much like the stock bar. This past weekend I moved the endlinks to the middle position (after close to 500 miles) and I'm totally happy with how much more responsive the car feels. One thing to mention is it will not fit with 17 inch wheels(as said in description of part).
