Subaru BRZ Sway Bar - Rear - Perrin Performance - 25mm Adjustable - `13-`25 is a direct-fit rear anti-roll bar designed for drivers who want sharper handling from their 2013–2025 BRZ. This Perrin 25mm adjustable sway bar tightens rear-end response and gives you on-demand tuning for cornering balance.

Engineered to replace the factory rear bar, this adjustable unit lets you dial in rear roll stiffness to match street driving or more aggressive track settings. Its 25mm diameter provides a meaningful increase in roll control while remaining predictable for daily use. The adjustability helps reduce body roll and can aid in balancing understeer/oversteer characteristics when paired with other suspension upgrades.

• 25mm adjustable rear bar for tunable roll stiffness
• Direct-fit for 2013–2025 Subaru BRZ mounting locations
• Multiple adjustment positions to fine-tune handling balance
• Designed for improved cornering with predictable behavior for street and track
