This graphite lower A arm plate mounts to the front lower arm area of the Yokomo R12-series chassis. It offers a removable reinforcement that changes local stiffness so drivers can tune handling without swapping the whole arm.
Installation is simple: secure the plate to the chassis' existing lower-arm mounting points. It installs and removes easily so you can compare setups; no alteration to the primary arm is needed when paired with compatible R12 front lower arm arrangements.
The plate is intended as a tuning tool. Fitting the graphite plate raises stiffness at the lower arm joint, sharpening front response and modifying weight transfer; removing the part returns the setup to its baseline feel. Use it for small-step adjustments to match track grip or driving preference.
