The Cusco OS rear strut bar ties the rear strut towers on Subaru BRZ and Toyota 86 to reduce chassis flex and improve rear-end stability. Installed across the rear shock mounts, it helps preserve suspension alignment during cornering and under load. This direct-fit rear brace adds torsional stiffness to maintain handling precision without changing stock components.
