Yokomo Y2-008FSRA Aluminum front short lower A arm (Right) for YD-2/4 series  [Y2-008FSRA]

That is an aluminum front side part component reduced a supply (right component just) you need to use for the YD-2/YD-4 show. By making the supply size also smaller versus resin brief supply and eliminating disruption combined with wheel, the switching angle is further increased, to operate at a deeper drift angle. Additionally, the increased fat improves the impression of front ground contact, and increased rigidity improves steering reaction. Made from aluminum with bevel part treatment, it's a lavish finish.
*when using with YD-4 show, another front component A-arm modification (Y4-AAC ●4, 200) is essential.
