The 3Racing Tamiya FF-03 Rear Upper Deck, model number FF03-13/WO, is aimed at racers who need clearer rear-end feedback and improved chassis stiffness. The component integrates with the FF-03 chassis architecture to provide a reliable mounting platform for setup adjustments.
Increasing rear stiffness reduces unwanted chassis flex, yielding a more predictable tail response during corner entry and mid corner tuning. This deck helps drivers extract consistent lap times by tightening the rear behaviour under lateral load.
Specifically manufactured for the Tamiya FF-03 series, the deck fits the original mounting points and requires standard RC tools for installation. Expect to adjust rear roll and damping to exploit the added stiffness when refining a race setup.
