Cobb 08-21 Subaru WRX/STI Rear Sway Bar Mount Reinforcement Kit - CB-1005

This powder coated brace mounts between the lower tab of the rear sway bar bushing mount and the rear inner lower control arm bolts. This provides added rigidity to the factory sway bar mount which is prone to cracking, especially with an upgraded sway bar.

Why?

As the saying goes, you're only as good as your weakest link. Upgrading the rear sway bar and end links on your Subaru can create added stress on the factory sway bar mount. This bracing helps to triangulate and add strength to the lower mounting point of the sway bar mount.
