This graphite lower A arm plate is intended to fit the front lower arm region of Yokomo R12-series chassis. It serves as an interchangeable reinforcement to alter local stiffness, enabling handling tweaks without replacing the full arm assembly.
Installation uses existing lower-arm mounting points on the chassis and is straightforward. The plate can be fitted or removed for direct comparison of settings; when used with compatible R12 front lower arm arrangements no modification to the main arm is necessary.
Functionally the plate is a tuning accessory. Installing it increases stiffness at the lower arm joint, changing front-end response and the way weight transfers under load; removing it restores the baseline feel. Incorporate it into small-step setup changes to match track conditions or driving approach.
