Yokomo YX-02A Aluminum Main Chassis for YR-X12  [YX-02A]

Aluminum main chassis for YR-X12

This aluminum main chassis is an aftermarket replacement plate designed for the YR-X12 1/12 competition racing platform. Machined from the supplied material specification, the plate aims to alter rigidity and the vehicle's centre of gravity to affect handling characteristics without changing suspension layout or electronics.

The chassis is a 2.0mm thick duralumin plate produced to the 70-75 specification noted in the source description. The thinner profile makes the chassis compatible with small-diameter tires and shifts weight lower in the chassis assembly, which helps reduce rolling tendencies and resist high-sides on carpeted surfaces.

Machining has been applied to preserve structural strength while balancing roll and pitch response. The outcome is a chassis that reduces excessive steering sensitivity on very high-grip tracks and provides a more predictable platform for fine-tuning suspension and tyre choices.

Installation is direct fit to YR-X12 mounting points; confirm fastener positions and clearances before final tightening. Use the chassis as part of an incremental setup change rather than a single dramatic adjustment to preserve drivability while seeking lap-time gains.

As a focused tuning part, this chassis is intended to refine balance and reduce sudden steering reactions on high-grip surfaces while supporting small-diameter tyre setups; use it alongside suspension and tyre adjustments to achieve the desired handling.
