Sway Bar

Carmen_SanDiego · 2026-03-08T23:54:12-0500

Hi, I own a 2014 FiST with the ST suspension coilovers and am not sure if I should get any sway bars. From what I know, the stock 2014 has a front sway bar and a torsion beam rear axle. Would it be worth buying a sway bar for front and back, just back, or leave it stock? Any brand recommendations would also me appreciated, thanks.

What is it you are trying to change about the cars handling? This will help people in making suggestions (if any).

For example, I wanted more/easier rotation on the track (I have BC coilovers with Swift springs, but should be fairly similar) so I have a Pierce Motorsports rear beam brace (mounts inside the rear axle beam) and a Whiteline 22mm rear sway bar, left the front stock but threw in some poly bushings.

Just the cornering ability

Any brace or sway bar added to the rear will make it more "tail happy" (oversteer), I haven't changed the front bar, so I cannot speak to if that will increase understeer or not, but it stands to reason that it may. So, if you want the rear to be a little more loose add a rear bar and/or brace, but if it's predominantly for street driving, it's not likely needed.

Also note that to swap the front bar, you need to drop the subframe, so it's quite a bit more involved than the rear. Installing the Whiteline rear bar I have was super easy, the bar, some spacers, and 4 bolts and nuts.

Thanks, I've been looking at the Whiteline rear bar as its used in the M2 Motoring's Fiesta SMEA build. I'll probably end up waiting to get a bar installed for a bit since as of now I mostly street drive.
