Replace the original resin upper arm with the Yokomo Y2-P08FUIA Aluminium Front Upper I-Arm to gain a stronger, longer lasting component. The aluminium part is crafted to minimise weight while increasing strength where it counts.
The spacer-based adjustment lets you alter caster by about 7mm, so you can tune steering feel for different track conditions and tyre choices.
Despite being made from aluminium, the arm is designed to stay light so your suspension response remains crisp while front-end stiffness improves.
When fitting this arm in place of the stock resin piece, use the D-155 series upper I arm rod end adapter to achieve a correct fit. It is intended to match YD-2 mounting patterns for an easy swap.
