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

Performance graphite lower deck for F103RM

This F103RM-05 graphite lower deck is a direct hop-up intended for the Tamiya F103RM racing chassis. Fitted as a replacement lower deck, it concentrates on increasing chassis stiffness and delivering repeatable feedback while setting up on the track. It is supplied as a tuning component, not a full chassis assembly.

The design mates to the F103RM mounting locations and acts as the main structural base for the chassis stack. By altering torsional stiffness the deck lets racers fine-tune balance and corner response through suspension geometry and weight placement changes.

Installation notes: the deck replaces the original lower deck without major changes to other components, and stock hardware is commonly reused. Always inspect mount alignment and clearance during initial assembly.

For racers aiming for a firmer handling baseline on the Tamiya F103RM, this graphite lower deck is an effective tuning upgrade; adjust setups in small steps to find the right balance.
