Tamiya F104 Competition Graphite Main - F104-13/WO by 3Racing  [F104-13/WO]

Competition-focused graphite main for F104

The F104-13/WO graphite main is a drop-in hop-up for the Tamiya F104 chassis range, engineered to alter torsional stiffness while maintaining factory mounting geometry. It replaces the standard main plate and is intended for drivers refining balance at race pace.

Manufactured for consistent flex characteristics, the graphite main shifts load transfer between the front and rear to influence mid-corner stability and transient behaviour. Use its stiffness change in combination with spring rates and anti-roll bar settings to dial handling for qualifying and race runs.

Fitting is a standard operation for experienced builders: remove the stock main plate, install the graphite unit in the existing mounts and confirm clearances around servos and wiring. After installation, validate screw torque and re-check suspension geometry to ensure setup targets are met.

Setup notes: evaluate the graphite main as part of an overall race setup. Its primary effect is on mid-corner support and response to throttle inputs, so adjust other chassis elements incrementally and record changes for consistent tuning.
