Overview: front lower A-arm for R12 models

The R12-10LFC front lower A-arm is a replacement suspension arm intended for RC-scale Yokomo R12 platforms. It is molded from a carbon-containing resin so riders get a firmer, more consistent response than from the stock plastic arm.

Practically, the stronger material boosts impact resistance during everyday track contacts and improves steering linearity and on-centre feel on high-grip asphalt surfaces. The component stabilises lower suspension geometry so small tweaks to camber, toe, or damper position translate into reliable handling changes.

Installation is the standard R12 procedure: detach wheel and steering linkages, unbolt the stock arm from upright and chassis mounts, then install the R12-10LFC using the original hardware and ball studs. Always check hinge pins and ensure free suspension travel prior to running.

Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How should I adjust setup after fitting the R12-10LFC?

Start by checking static camber and toe, then run a brief on-track test. The increased front stiffness often calls for small toe or damper adjustments to restore the preferred turn-in balance.

Does this arm affect roll center or geometry noticeably?

The arm itself mainly stabilises lower geometry; while it does not change measured roll center, the firmer behaviour makes setup changes more predictable and can alter perceived roll and turn-in.

Will tyre wear be affected after installing this arm?

Improved steering linearity can lead to more consistent tyre loading and, in many cases, more even wear. Monitor tyre condition and adjust alignment if you notice uneven scrub.
