Cusco Rear Upper Arm for Toyota 86/Subaru BRZ/Scion FR-S (ZN6/ZC6)
also fits Subaru WRX (GVB, GRB, VAB)
Increasing the vehicle track width with low offset wheels can lead to a number of issues like off-center loading, and alignment swing arc.
To do this properly without losing suspension capability and effectively enhancing performance with wider track, Cusco has created a number of components.
For the rear, we have an adjustable upper and lower arm set which enable just that.
These not only allow proper loading of rear suspension, brakes, and hub components, it will allow a wider choice of wheel and tire widths to be properly set.
Suggested use with other Cusco suspension parts to allow maximum adjustment range and bushings/joint loading characters.
Wide Body Done Properly
With Street Wide-body applications the Cusco upper arm will allow for the same benefits as above, but in addition, enable perfect fender to tire fitment via adjustability without use of spacers for up to 15mm adjustment in inward and outward hub offsets.
This without having more ideal camber and caster settings when used with other Cusco rear suspension components to retain proper alignment settings for safety.
And durable, fracture resistant steel pipe materials help to ensure long-term use.
