Upgrade the handling performance and adjustability of your Subaru BRZ (ZN6) with the CUSCO Adjustable Rear Upper Arms — engineered for precision, strength, and race-ready durability.
-
High-Strength Steel Construction:
Constructed from reinforced steel piping, these arms are built to withstand the high lateral loads and impacts generated by racing compound tires and aggressive driving.
-
Turnbuckle Camber Adjustability:
Features an upper-side turnbuckle design offering ±15mm of camber adjustment, allowing for fine-tuned rear wheel alignment tailored to your specific driving style, tire setup, and ride height.
-
Hard Rubber Bushings:
Equipped with hardened rubber bushings to minimize unwanted alignment changes and deliver a more direct and predictable steering response under load.
-
Direct OEM Replacement:
Designed as a bolt-on replacement for the factory rear upper arms. Installation time is approximately 1.0 hour (does not include alignment time).
-
Improved Tire Contact & Cornering Performance:
Additional negative camber enhances tire contact patch during cornering, improving grip and stability on both track and touge applications.
-
Precision Fitment & Clearance Control:
Allows for accurate adjustment of tire-to-fender clearance — ideal for lowered vehicles and wide wheel setups.
CAMBER ADJUSTMENT RANGE (Approximate Values):
- Rear Camber with OEM Arm: -2.5°
- Rear Camber with CUSCO Arm (adjusted to -15mm): -7.5°
