Improve TRF419XR chassis behaviour with Tamiya carbon lower deck

For drivers who want crisper cornering and better stability on the track, the Tamiya 3404072 CFRP Lower Deck fits the TRF419XR chassis and offers a strong, lightweight alternative to stock plates. Made from Carbon Fiber Reinforced Polymer, it raises chassis rigidity while trimming unnecessary mass.

Track-focused advantages of CFRP

CFRP delivers an excellent strength-to-weight ratio, helping the car respond quicker to steering inputs and hold lines more consistently. These traits are useful for club racing and lap time improvements where precision matters.

Fitment notes and installation tips

This lower deck is designed specifically for the TRF419XR, so alignment and hole positions match the chassis. When fitting, tighten screws evenly and avoid over-torquing carbon fasteners. Check clearances and recheck hardware after a few runs.
