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

Graphite lower deck upgrade for F103RM handling

This F103RM-05 graphite lower deck is a direct hop-up built for the Tamiya F103RM racing platform. It replaces the standard lower deck to give a firmer chassis foundation and clearer feedback during setup, intended as a tuning item rather than a stand-alone assembly.

When installed the deck lines up with existing F103RM mounting points and becomes the structural base of the chassis stack. It modifies torsional characteristics so tuners can dial in balance and front-to-rear response through suspension and ballast adjustments.

Installation notes: designed for drop-in replacement of the original lower deck on F103RM chassis; retain stock fasteners when possible and verify fitment and clearance before track running.

For drivers looking to sharpen chassis behaviour on the Tamiya F103RM, this graphite lower deck is a focused upgrade for setup work; tune progressively to reach the handling you want.
