Whiteline Rear Sway Bar Mount Support Brace - 2013-2020 BRZ / GT86 / FR-S

Reinforce Your Handling: Eliminate Sway Bar Mount Flex
The 1st Generation Subaru BRZ, Scion FR-S, and Toyota 86 are legendary for their handling, but their factory rear sway bar mounting brackets are a known weak point. Under heavy cornering loads—especially when upgraded with a larger aftermarket sway bar—these thin factory brackets can flex, bend, or even crack over time. The Whiteline KBR38 Rear Sway Bar Mount Support Brace provides the structural reinforcement needed to keep your suspension geometry consistent.

Structural Integrity for Performance Driving
Built from high-strength steel, the KBR38 acts as a bridge between the sway bar mount and the chassis. By adding this secondary mounting point, you ensure that the forces from the sway bar are transferred directly into the chassis rather than being lost to bracket deflection. This results in a more predictable rear end and ensures your sway bar is actually performing at its intended stiffness.

• Prevents Bracket Failure: Protects the OE mounting points from cracking or fatiguing under high loads.
• Maximizes Sway Bar Efficiency: Eliminates mount flex so your sway bar can react faster to cornering forces.
• Corrosion Resistant Finish: Finished in a durable coating to withstand the elements and maintain a professional look.
• Essential for Upgraded Bars: Highly recommended for any 1st Gen BRZ/86 using an upgraded, stiffer rear sway bar.
