Product Details
ISR Performance Rear Differential Mount Support Brace for the 2013-2016 Scion FR-S (ZN6) are built to add rigidity to a known flex point on the chassis so the suspension mounts can work with the geometry they were designed around. 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 differential mount support brace 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
- Adds chassis rigidity at a high-flex stress point
- CNC-machined or laser-cut steel construction
- Bolt-in — no drilling, no welding
- Reduces chassis deflection for sharper turn-in
