Tamiya F104 Graphite Main Plate - Handling Upgrade F104-13/WO by 3Racing  [F104-13/WO]

F104 graphite main for handling upgrades

The F104-13/WO graphite main is a purpose-made hop-up that replaces the standard main plate on Tamiya F104 chassis while retaining the original mounting configuration. It lets you alter chassis stiffness without changing the overall layout.

Produced in graphite, the plate emphasises rigidity and repeatable flex behaviour. Installing a graphite main alters how the chassis transmits forces between the front and rear, a useful result when tuning understeer or oversteer on carpet or asphalt circuits.

Fitting requires basic familiarity with the F104 platform: remove the original main, locate the graphite unit into the factory mounts and confirm servo lead and cable clearances. Verify screw tightness and re-check chassis geometry after installation.

Setup guidance: use the graphite main as one element in a broader setup plan with springs, anti-roll bars and ride height changes. Its main effect is on mid-corner stability and transient feel, so adjust progressively and test on your preferred surface.
