What this part does

This graphite rear upper deck plate fits the Tamiya F103GT chassis and is supplied as part number F103GT-21/SG. It is an RC hop-up intended to alter rear chassis torsion to affect handling and balance for 1/10 GT-style driving.

The upgrade replaces the original rear upper deck and bolts in using the F103GT's existing mounting points, keeping the swap quick and simple. Graphite gives higher stiffness than many stock plastics, limiting unwanted flex during lateral manoeuvres while remaining light enough for racing use.

Choose this plate when you want chassis-level tuning rather than suspension-only tweaks. The stiffer deck will change rear traction behaviour and transient response, so run controlled tests to find the best setup.

Do I need new screws or hardware to fit this plate?

In most cases the stock hardware is usable since the plate mounts to the same points, but inspect screws for wear and replace if they are damaged.

Will the deck affect lap times?

A stiffer rear deck can improve corner consistency and help lap time by stabilising the chassis, but gains depend on track, tyres, and driver setup.

How should I evaluate changes after installation?

Run baseline laps before and after fitting, keep tyre pressures and battery state consistent, and make small setup adjustments to springs or roll bars to compensate for the deck change.
