Features & Product Details
RallySport Direct carries a great selection of Whiteline Suspension Products to improve the handling and ride quality of your vehicle.
These are the Whiteline Rear Swaybar Mount Support Braces. These have been designed to increase the overall stiffness of the rear swaybar mounting brackets to reduce the likelihood of bending or cracking of the OEM mounts due to the increase of the loads. The stock mounts are known to bend under hard driving conditions which will reduce the ability of your rear sway bar which will have an effect on your handling in general.

I put these on my 2016 WRX (They fit as the suspension dimensions are the same) with another swaybar that I purchased second hand and it helped brace the swaybar incredibly well. No issues whatsoever and it was a very easy and straightforward install
I purchased these when I upgraded my rear control arms with adjustable ones. I knew I had to remove the bolts anyways so I figured I might as well add these. To my surprise it feels like I installed a thicker sway bar. These are a great upgrade at a good price.
After looking at the stock sway bar mounts you cannsee their inefficiency. The stock mounts are on a piece of steel coming off the rear crossmember and kind of float in midair. With the whitelines it ties them into the lca bolts to give them the support they need. Install was perfect with no fitment issues at all. 4 bolts/nuts to loosen and retighten to install. The lca bolts dl require some real strength to loosen but beside that its a simple install
As several others have commented - passenger side support brace is a few millimeters short and will not sit flush against the subframe. Another reviewer mentioned using spacers... I just removed some material to allow better fitment against the subframe (bench grinder) and widened the bolt hole (rotary grinder) to reduce any pre-tension. Driver side bolted up perfectly! The finish on this item sucks. Paint will chip during installation - just expect it to, because it will, it probably already has, just sayin. Do you need this? Nope.
it doesn't fit. it s short on the passenger side. I also purchased the KSB723 front lower control arm brace with poor fitment. the brace was 1/4 short from lining up. I do not recommend.

A: It looks like it may work. Although it may require some modification. We can't confirm the fitment 100% unfortunately.
