Toyota GR86 Rear Sway Bar — Perrin Performance 16mm Adjustable (2013–2025). A direct-fit rear anti-roll bar designed to reduce body roll and help you dial in rear-end balance for more confident cornering on street and track.

This PERRIN 16mm adjustable rear sway bar is engineered as a bolt-on upgrade for 2013–2025 BRZ/FR-S/86/GR86 platforms. The adjustable design lets you select stiffer or softer rear roll resistance to tune handling characteristics without altering springs or dampers. Ideal for enthusiasts who want improved rotation and better mid-corner control while retaining everyday drivability. The bar installs using existing mounting points for a straightforward swap.
