Product Details
ISR Performance Rear Trailing Arms for the 2013-2016 Scion FR-S (ZN6) are built to control rear wheel squat and hop under hard acceleration, keeping the rear axle planted when you dump the clutch. If you've lowered the FR-S on coilovers or dropped springs, factory hardware in this location can no longer keep the alignment honest — these parts solve that problem and sharpen how the chassis feels under load.
Every ISR rear trailing arms set uses CNC-machined billet construction with performance-grade spherical bearings or poly bushings where appropriate. Bolt them in using OEM mounting points — no welding, no cutting — and get the ZN6 FR-S back into alignment spec with the adjustment range daily-driven, canyon-carved, and track-day FR-S owners actually need.
Features
- Adjustable to correct rear wheelbase and squat under launch
- CNC-machined body with oversized hardware for chassis bracing duty
- High-misalignment spherical bearings for articulation
- Direct bolt-in fit to OEM mounting points
