Tamiya 84394 FF-04 Evo Double-Deck FWD Racing Kit  [84394]

Optimised On-Road Handling with the Tamiya 84394 FF-04 Evo

The Tamiya 84394 FF-04 Evo Chassis Kit advances the front-motor FWD concept with focused improvements for track use. Drawing on lessons from prior FF designs, the Evo balances stiffness and lightness to improve steering precision and lap-to-lap consistency. Its specification aims to give tuners a solid starting point for competition setup.

Carbon Double-Deck and Suspension Layout

The carbon double-deck arrangement uses a 2.5mm thick lower deck and a 2.0mm upper deck to maintain torsional rigidity while controlling overall weight. Suspension geometry influenced by the TRF418 provides fully independent double wishbones so tyres stay in better contact with the surface. A sealed oil-filled gear differential in an XV-01 inspired gearbox helps smooth drive during corner exits.

Durable Components for Accurate Setup

The kit is stocked with performance-focused parts. TRF dampers with a hard black coating offer precise damping, aluminum turnbuckle shafts allow accurate alignment checks, and fluorine-sealed ball bearings reduce friction across rotating parts. Double cardan drive shafts support efficient power transfer and tighter throttle control.

Designed for experienced model racers, the Tamiya 84394 FF-04 Evo delivers a refined FWD chassis that responds well to setup changes and performance upgrades.
