This front lower A-arm serves as a direct replacement for the standard plastic arm used on RC-scale Yokomo R12 platforms. Manufactured from a carbon-containing resin, it offers a firmer, more consistent response than the stock item.
In real-world running the tougher material improves impact resistance during typical on-track contacts while delivering better steering linearity and on-centre feel on high-grip surfaces. The arm helps to stabilise the lower suspension geometry so small setup changes to camber, toe, or damper settings produce more repeatable handling responses.
To install, follow normal R12 front lower arm replacement steps: remove the wheel and steering linkages, unbolt the original arm at the upright and chassis mount, then fit the R12-10LFC using the existing hardware and ball studs. Always confirm hinge-pin security and free suspension travel before use.
