Swap out brittle resin arms for the Yokomo Y2-P08FUIA Aluminium Front Upper I-Arm to boost reliability. The part is machined to give a solid front end without adding unnecessary heft to your car.
This I-arm lets you shift the spacer to change caster over a 7mm span, so you can tune understeer and turn-in balance across different track surfaces.
The aluminium construction reduces flex while keeping mass low, helping maintain sharp steering inputs and predictable corner behaviour.
When replacing the stock resin arm, fit the D-155 series upper I arm rod end adapter to ensure proper geometry. The design integrates with YD-2 mounting points for a straightforward installation.
