The 3Racing F104-12/WO upper deck is a precision component aimed at drivers tuning the Tamiya F104 chassis. Its graphite construction reduces chassis compliance and is laid out to accept typical LiPo pack formats, helping maintain consistent suspension geometry under race load.
Adopting this graphite deck improves torsional stiffness which aids predictable weight transfer and turn-in response. The change in flex characteristics may require small setup adjustments to differential and anti-roll settings to optimise balance.
The deck is machined to align with standard Tamiya F104 mounting points for a straightforward swap. When fitting, verify battery strap position and cable routing to ensure the pack sits secure and does not interfere with steering or suspension linkages.
