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

Graphite lower deck for F103RM

This 3Racing F103RM-05 graphite lower deck is a direct hop-up intended for the Tamiya F103RM racing chassis. As a replacement lower deck it focuses on chassis stiffness and predictable feedback during on-track setup, serving as a tuning component rather than a standalone assembly.

In practical use the part integrates with the F103RM mounting points and works as the structural base for the chassis stack. Its role is to alter torsional characteristics so drivers can fine-tune balance and corner response through suspension and weight distribution adjustments.

Installation notes: the deck is designed to take the place of the original lower deck on F103RM chassis without modifying other major components, components and hardware from the stock lower deck are typically transferred during fitment. Verify alignment and clearances on first assembly before track use.

For racers seeking a firmer baseline on the Tamiya F103RM, this graphite lower deck is a targeted upgrade to refine chassis feel and assist in setup tuning; evaluate changes incrementally to match handling preferences.
