Improve Precision on the F104 with an Upper Deck

Competitive drivers and devoted hobbyists will find the Tamiya 4005142 RC Upper Deck a useful upgrade for the F104 chassis. It reduces chassis flex to give steadier handling and a more predictable steering response on track.

Main Benefits of the Upper Deck

Engineered for the F104 series, this upper deck fits the original mounting points and is straightforward to install. By firming up the chassis it enhances corner entry stability and reduces mid corner flex, allowing finer suspension adjustments for lap time improvements.

Will the Tamiya 4005142 change how I set camber and toe?

Because the deck reduces chassis flex, you might need to revisit camber and toe to optimise tyre contact and avoid unexpected understeer or oversteer.

Is the upper deck compatible with carbon and alloy variants?

The part is intended for standard F104 chassis. It will fit most carbon or alloy top decks that retain original mounting geometry, but check alignment before final assembly.

How often should I inspect the deck after racing?

Inspect mounting screws and contact surfaces after each meeting or heavy session. Tighten hardware and check for signs of wear to keep handling consistent.

Can upgrades complement this deck?

Yes. Pairing the upper deck with tuned dampers, stiffer anti-roll bars or adjusted spring rates lets you exploit the increased chassis stiffness for better lap times.
