Tamiya 54278 Separate-Type Upper Deck Set for F104/F104W - Chassis Flex Kit  [54278]

Refine F104 handling with the separate upper deck

The Tamiya 54278 Separate-Type Upper Deck Set is a practical two-piece option that reduces overall chassis stiffness to help the car maintain better tyre contact through corners. By softening the upper structure, drivers can achieve improved traction and a more forgiving balance when tuning for different tracks.

How the split design affects handling

Reducing rigidity allows the chassis to flex more naturally, which can stabilise cornering and make weight transfer easier to manage. This kit is useful for fine-tuning balance without extensive component swaps.

Best for mixed surface tracks

The separate upper deck suits a range of surfaces from smooth asphalt to rougher club circuits. Adjusting chassis compliance with this set helps tyres stay planted, giving more consistent feedback lap after lap.
