Whiteline Sway Bar Mount Support Brace Subaru WRX / STI 2008-2021 | KBR15

Shipped fast, and product quality is fantastic

Removed 4 bolts total (2 per side). Does not affect alignment.

Had to add these with my sway bar kit from Whiteline to complete the package. Great quality product!

It looks good on and its sturdy. With the swaybars done too, it completed the suspension feel.

These braces added a lot of rigidity and stiffness to the rear and helped with the Perrin 25 mm sway bar I installed. There are some very minor popping sounds intermittently but overall I’m very happy after my past weekend spirited drive through the Georgia mountains. I did paint them red to match my Perrin rear sway bar and slapped some Perrin. Stickers on them also just to keep theme. Great braces so far!

First, I would like to say you notice a difference more with a bigger sway bar, as the torsion increases as the bars stiffness increases, thus showing the weakness in the mounts, however, even on a factory sway bar, it’s still a noticeable difference. It really helps ensure there is little to no movement in the sway bar, increasing the effectiveness of the sway bar. For the money, it’s a solid mod that will help the rear end rigidity and help the car rotate through the corners more effectively.
