For tuners and racers aiming for a firmer rear end, the Yokomo Y2-301D2A Machined Aluminum Rear Suspension Arm Mount replaces the stock resin bush. Its aluminium build is intended to provide a steadier pivot point and a more predictable rear feel during lap after lap running.
The Y2-301D2A is crafted to align with the short rear suspension arm layout used on YD-2 cars, enabling a clean installation. With improved material stiffness, the mount helps reduce flex under load and sharpens turn-in and mid-corner balance.
Aluminium delivers a strong but lightweight solution for suspension mounts, resisting wear better than resin and helping maintain setup settings under stress. Users focused on consistent lap times often upgrade to aluminium components for that reason.
