The COBB rear sway bar mount reinforcement kit for 2008–2021 Subaru WRX and WRX STI strengthens the rear sway bar attachment points to help prevent mounting wear or deformation. It’s a direct-fit reinforcement intended to support the rear stabilizer hardware under increased loads. The kit is a practical upgrade for owners looking to preserve factory sway bar function during spirited driving or modified setups.
