Race grade graphite lower deck for setup and tuning

The 3Racing F103RM-05 graphite lower deck is manufactured to deliver consistent stiffness across the chassis, aiding precise setup work and predictable dynamic changes. Its geometry keeps the original mounting points so shock tower and bulkhead relationships remain unchanged while torsional compliance is reduced.

Technical highlights

  • Material: High modulus graphite chosen for low deflection under racing loads
  • Compatibility: CNC trimmed profile to fit the Tamiya F103RM chassis layout
  • Function: Improves chassis torsional rigidity to make suspension adjustments more effective
  • Application: Intended for racers tuning handling balance and seeking repeatable setup changes

What setup areas are most affected by increased deck stiffness?

Front/rear roll coupling and antiroll bar effectiveness change the most; expect to retune spring rates and droop to regain desired transient response.

Does this part require trim of other components during installation?

No component trimming should be needed. Verify fitment against the chassis reference points and check fastener torque to maintain consistent stiffness.

How should I validate performance after fitting the deck?

Run a control lap programme, log handling changes, and adjust one variable at a time so you can quantify the effect of the deck on understeer, oversteer and midcorner stability.
