R12 Graphite Main Chassis for R12 - R12-02 by Yokomo  [R12-02]

Key features and purpose

This Yokomo R12-02 graphite main chassis is a replacement part made for the R12 platform. As the principal torsional member it defines chassis stiffness and therefore changes how the car responds to steering inputs, weight transfer, and suspension setup. The text emphasises compatibility and installation notes rather than making specific performance claims.

During installation the component replaces the factory main chassis and locates on the original mounting points for motor, suspension and electronics. Inspect motor mount and bulkhead alignment during fitment and confirm clearances for the servo, ESC and battery before first running. When used with an unmodified R12 kit only minimal trimming should be necessary.

From a setup viewpoint the graphite main chassis alters flex characteristics compared with composite alternatives. Drivers often use chassis selection to tune mid-corner stability versus turn-in by matching chassis stiffness with shock damping, anti-roll bars and ride height. Small adjustments to mounting orientation and stack height can change overall balance.

Fit this chassis as a direct replacement when refreshing or reconfiguring an R12 kit, and treat it as a tunable variable during track testing.
