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

Graphite main for F104 racers

This F104-13/WO graphite main is a direct-fit hop-up for the Tamiya F104 chassis family. As the dedicated main plate it replaces the standard item and uses the same mounting points to change chassis stiffness characteristics without altering the basic layout.

Made from graphite, the plate prioritises structural rigidity and consistent flex. Swapping the stock main for a graphite unit alters load transfer between front and rear, which you can use when trimming understeer or oversteer on carpet or asphalt surfaces.

Installation is straightforward for anyone familiar with the F104 platform: remove the original main plate, fit the graphite part into the existing mounts and confirm clearances for servo leads and nearby components. Re-check screw torque and vehicle geometry after fitting to ensure the handling changes are as expected.

Tuning notes: treat the graphite main as one tuning element alongside springs, anti-roll bars and ride height. Its primary influence is on mid-corner stability and transient response, so make incremental adjustments and test on your chosen track surface.
