Description
Improve rear-end rigidity and harness mounting safety with the Cusco Rear Trunk Plus Harness Power Brace for the Subaru BRZ ZD8 and Toyota GR86 ZN8. Developed from Cusco’s motorsport chassis data, this brace reduces body flex under cornering loads so the suspension can work in its ideal geometric range. The result is a more predictable rear end, sharper response and improved stability, whether the car is stock or highly modified. Constructed from lightweight steel and designed using advanced chassis stress simulation, this Power Brace is a bolt-on solution that can also function as a safety harness bar. Some minor trimming of interior or under-cover panels may be required for installation.
