Tamiya 4025067 F103R Upper Deck Upgrade  [4025067]

Stiffen Your F103R with the Tamiya Upper Deck

The Tamiya 4025067 RC upper deck is a direct-fit upgrade for the F103R chassis that adds meaningful torsional stiffness. By reinforcing the centre section, it helps reduce flex at speed so handling feels more predictable and controlled. Built to integrate cleanly with stock mounting points, it balances durability with precise fit.

Racing-Focused Chassis Enhancement

Made with competition use in mind, this upper deck increases chassis rigidity for sharper turn-in and steadier high-speed runs. Whether competing or refining lap times during practice, the 4025067 improves responsiveness without complicated installation. Its construction stands up to repeated track sessions and routine race demands.
