YR-X12 2.0mm Duralumin Chassis Plate - YX-02A by Yokomo  [YX-02A]

Low-profile duralumin chassis for YR-X12

This aftermarket aluminum main chassis is built as a replacement plate for the YR-X12 1/12 competition platform. It is machined to the quoted material standard and intended to modify torsional behaviour while keeping suspension and electronics unchanged.

The component is a 2.0mm plate produced to the 70-75 duralumin grade. The slimmer profile suits small-diameter tyre packages and moves mass lower in the car, helping to limit roll and curb high-side incidents on carpeted surfaces.

Strategic machining maintains necessary strength where it is critical and balances roll versus pitch reaction. Drivers will notice reduced twitchiness at the limit and a steadier handling baseline for detailed setup work.

Fitment is a direct replacement to YR-X12 mounting points; confirm alignments and clearances before final assembly. Introduce this change alongside iterative adjustments to suspension and tyres for controlled progress toward quicker lap times.

As a precision tuning part, this chassis helps harmonise handling and cut down abrupt steering inputs on high-grip carpet; use it in concert with tyre and damper changes to fine-tune lap performance.
