Tamiya F103RM Track Graphite Lower Deck F103RM-05 by 3Racing  [F103RM-05]

Chassis graphite lower deck for F103RM tuning

This F103RM-05 graphite lower deck is a straightforward hop-up for the Tamiya F103RM race chassis. As a replacement lower deck it focuses on raising chassis rigidity and producing predictable feedback during setup work, intended solely as a tuning upgrade rather than a full chassis replacement.

The component aligns with the F103RM factory mounting points and forms the structural base for the chassis stack. By changing torsional stiffness the deck helps drivers refine balance and corner response through suspension and weight distribution adjustments.

Installation notes: fitted to replace the OEM lower deck without modifying major components; reuse stock fasteners where possible and confirm clearances on first assembly before competitive use.

For competitors seeking a firmer handling baseline on the Tamiya F103RM, this graphite lower deck offers a targeted way to tune chassis behaviour; implement setup changes gradually to evaluate their effect.
