Yokomo R12-10LP Lower A arm Plate for YR-R12C3/GT, graphite lower A-arm reinforcement  [R12-10LP]

Lower A arm reinforcement for R12

This graphite lower A arm plate is designed to mount to the front lower arm area of the Yokomo R12-series chassis. It provides an interchangeable option to alter the effective stiffness of the front lower arm assembly, letting drivers adjust handling characteristics without replacing the entire arm.

Fitment and installation are straightforward: the plate attaches using the chassis' existing lower-arm mounting points and can be installed or removed to compare settings. No modification to the main arm is required when used with compatible R12 front lower arm layouts.

Functionally, the plate's role is tuning-focused. Adding the graphite plate increases local stiffness at the lower arm joint, which changes front-end response and weight transfer behavior; removing it returns the assembly to the baseline feel. Use the plate as part of small-step tuning when matching setup to track surface or driving style.
