Tamiya F104 Graphite Main Plate - Track Tuning F104-13/WO by 3Racing  [F104-13/WO]

Graphite main plate for F104 track use

The F104-13/WO graphite main is an aftermarket hop-up that directly replaces the stock main on Tamiya F104 chassis. It uses the original mounting points so chassis layout remains unchanged while stiffness characteristics are altered.

Graphite provides a stiffer backbone and controlled flex. Swapping in a graphite main shifts how the chassis carries loads front to rear, which can be leveraged to influence understeer or oversteer on carpet or bitumen surfaces.

Installation is familiar to F104 owners: remove the existing main plate, fit the graphite unit into the same mounts and check servo and cable clearances. Confirm fastener tightness and re-check wheel alignment and ride height before track testing.

Setup advice: pair the graphite main with spring, anti-roll bar and ride height changes to find the desired balance. Its main impact is on mid-corner stability and short-term response, so make small changes and test each step.
