This graphite reinforcement is an accessory for competition 1/12 racing, engineered to work with Yokomo YR-X12 series chassis. It provides a way to adjust chassis rigidity without swapping the main chassis plate.
Fitting is intended for those experienced with 1/12 touring car service: the brace secures to the factory mounting points on YR-X12 and YR-X1219 chassis and is used with the car's original hardware. No extra components are assumed to be supplied, so hold onto your existing screws and mounts when installing.
In tuning terms the brace reduces torsional flex and modifies how weight moves through corners; small, measured adjustments of chassis stiffness using parts like this can change front end bite, mid-corner balance and transient behaviour. Use progressive testing on the track to evaluate changes rather than broad simultaneous setup shifts.
