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

Track-focused graphite lower deck for F103RM

This F103RM-05 graphite lower deck is a direct hop-up designed for the Tamiya F103RM racing chassis. As a replacement lower deck it prioritizes chassis stiffness and more predictable feedback during track setup, acting as a tuning component rather than a complete assembly.

In practice the part bolts into the F103RM mounting points and serves as the structural base for the chassis stack. Its primary role is to change torsional characteristics so drivers can refine balance and cornering feel through suspension and weight distribution tuning.

Installation notes: the deck is made to replace the stock lower deck on F103RM chassis without modifying other major parts, and hardware from the original lower deck is usually transferred during fitment. Check alignment and clearances on first assembly before taking the car to the track.

For racers wanting a firmer baseline on the Tamiya F103RM, this graphite lower deck gives a precise way to tune chassis feel; make incremental setup changes to match your handling goals.
