Tamiya 54278 Upper Deck Set for F104/F104W - Adjustable Flex Kit  [54278]

Improve cornering by adjusting chassis compliance

The Tamiya 54278 Separate-Type Upper Deck Set is a two-piece upper deck that lowers chassis stiffness to help tyres maintain contact during cornering. This option is aimed at drivers who want more control when tuning handling for different track types.

Handling advantages of the split top plate

By separating the upper deck you gain more nuanced flex behaviour, which can make the car easier to place in mid corner. It is a straightforward way to alter balance without replacing major components.

Ideal for varied club and indoor tracks

From smooth indoor layouts to coarser outdoor circuits, altering the deck stiffness can improve traction and help reduce snap oversteer in tricky sections.
