Product Details
ISR Performance Rear Trailing Arms for the 2022+ Subaru BRZ (ZD8) 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 BRZ 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 ZD8 BRZ back into alignment spec with the adjustment range daily-driven, canyon-carved, and track-day BRZ 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
