Tamiya 42311 TRF419X WS High-Performance Touring Chassis  [42311]

Tamiya 42311 TRF419X WS: Kit Overview

The Tamiya 42311 TRF419X WS chassis kit updates the TRF419X platform with targeted upgrades for on-road competition. Enhanced upper and lower deck components focus the chassis behaviour for sticky surfaces like carpet and grippy tarmac. Offering both a 2mm aluminium chassis plate and the carbon decks, this kit gives racers a practical way to tune stiffness and feel.

Engineering Highlights

By lowering the front and rear shock towers, the TRF419X WS reduces the centre of gravity to help with stability and responsiveness, especially when fitted with low-nose sports car shells. This setup improves aerodynamic interaction at speed.

The modular bulkhead includes detachable inner camber link mounts to allow precise camber link length selection. Sway bar mounting now uses stabiliser stoppers to curb excess motion and refine handling balance.

Flex Control and Shock Tower Design

Switching to a two-screw mount for carbon shock towers increases chassis flex compared with the older four-screw arrangement. Racers can use this characteristic to tune entry grip and mid-corner behaviour without altering major suspension geometry.

The Tamiya 42311 TRF419X WS is a flexible platform aimed at competitive hobbyists who want multiple setup paths and material options to suit varied track conditions.
