What other subaru models rear sway bar fit brz/frs

Some of the OEM bars are the same as ours, like wrx for example. Possibly forester as well. Does anyone know what years and what models will fit?

Also does anyone know of those models, which have 17mm or 18mm rear bar?

2008-2014 STi has an oem 18mm bar that fits our cars.

Not sure what size the 2015-2022 has.

2013-20?? impreza has the same rear subframe as the twings, so all the bars can be swapped between the impreza, wrx, and sti


I'm currently running a 2014 impreza bar that is a tiny bit stiffer than the stock one.

Are there any stock bars that are smaller than the BRZ/FRS/86 that fits? (Mann Engineering alternative)

The closest I can think of is Cusco. It's the same size as 13-16 14mm sway bar except it's hollow so it'll be softer.

I believe that somehow (material, bends, etc) the Cusco 14mm is stiffer than the oem 14mm.

Unfortunately none. The 2004 legacy b12 has a 13mm bar but itís a different shape than ours.

I saw an outback sport the other day and it didnít have any endlinks where ours normally are. I thought that maybe it doesnít come with a rear bar (which would be the softest option), but turns out they put it in an insanely difficult place to see/access.

"The rear stabilizer is now attached directly to the body of the car. Removal of the rear stabilizer bar requires removal of the rear sub frame and all related components."

It's listed as 73% as stiff as the factory 14mm solid.

Well I stand corrected. That should make it the only option besides Mann Engineering that is softer than stock.
