Tamiya 84394 FF-04 Evo Carbon Fiber FWD Touring Kit  [84394]

Race-Ready Engineering in the Tamiya 84394 FF-04 Evo

The Tamiya 84394 FF-04 Evo Chassis Kit marks a clear step forward for front-motor, front-wheel-drive RC platforms. Building on earlier FF-series designs, this kit brings targeted refinements for racers who value predictable handling and chassis balance. Its carbon fiber double-deck layout and quality components are aimed at improving cornering stability and response on the track.

Chassis Design and Dynamics

The heart of the FF-04 Evo is its carbon fiber double-deck construction, with a 2.5mm lower deck and a 2.0mm upper deck to maintain stiffness while keeping weight low. Suspension takeaways from the TRF418 deliver a fully independent double wishbone setup for consistent wheel control. Power is managed via a sealed oil gear differential housed in an XV-01 style gearbox to reduce traction loss during turning maneuvers.

High-End Parts and Hardware

Key components supplied with the kit focus on precision and durability. TRF-style dampers with a hard black finish provide reliable shock absorption, aluminum turnbuckle shafts allow fine toe and camber adjustment, and fluorine-sealed ball bearings keep driveline friction low. Double cardan drive shafts improve drivetrain efficiency for crisper acceleration.

The Tamiya 84394 FF-04 Evo Chassis Kit suits experienced on-road drivers seeking a stiff, lightweight platform with precise handling and upgrade potential.
