Product Details
This ISR Performance rear differential mount support brace fits the 2013-2020 Subaru BRZ RWD (ZC6).
ISR Rear Differential Mount Support Brace for the ZC6 BRZ 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. On a car lowered on coilovers or springs, the factory hardware in this location no longer holds alignment. These parts correct it.
Every ISR rear differential mount support brace set uses CNC-machined billet construction with performance-grade spherical bearings or poly bushings where appropriate. They bolt in at the OEM mounting points with no welding or cutting and bring the car back into alignment spec.
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
