This is an RC-scale front lower A-arm spring for the Yokomo R12/GT series designed for carpeted surfaces. The component replaces the front lower arm spring in the R12/GT front suspension, providing a specific spring profile intended for carpet track behaviour.
Compatibility is limited to the R12/GT series, and the spring follows the model designation R12-10S1 as a direct-fit replacement for the stock front lower A-arm spring. Installation involves removing the front lower arm assembly, swapping the spring element, and reassembling the suspension to factory geometry.
In tuning terms this spring is intended to influence front-end compliance and turn-in response on RC carpet layouts. Use it when adjusting front suspension balance for grip and steering feel, and evaluate changes incrementally to understand its effect on handling.
