Tamiya 42311 TRF419X WS Competition Touring Chassis Kit  [42311]

Inspecting the Tamiya 42311 TRF419X WS Kit

The Tamiya 42311 TRF419X WS chassis kit is a competition-focused touring car base engineered for responsive handling on high-traction layouts. It upgrades the TRF419X with revised upper and lower decks to sharpen behaviour on surfaces such as carpet and high-grip asphalt. The kit includes a 2mm aluminium chassis option in addition to the carbon decks so racers can pick the stiffness profile that suits their track.

Notable Engineering Changes

Lowering the front and rear shock towers reduces overall centre of gravity, which benefits stability when fitted with low-nose sports car bodies. The change improves aerodynamic performance and helps keep the chassis settled through fast turns.

The modular bulkhead design features removable inner camber link mounts for flexible camber link length settings. Stabiliser stoppers on the sway bar mounts provide a more controlled roll response and tighter handling feel.

Fine Tuning Chassis Behaviour

Adopting a two-screw attachment for the carbon shock towers increases the chassis flex range compared with the prior four-screw method. This gives racers an additional tuning variable to influence traction and turn-in without altering core suspension geometry.

The Tamiya 42311 TRF419X WS is intended for competitive modellers seeking a configurable touring car chassis with multiple tuning options for different track surfaces.
