Tamiya 84394 FF-04 Evo Precision FWD Touring Kit  [84394]

Fine-Tuned Handling with the Tamiya 84394 FF-04 Evo

The Tamiya 84394 FF-04 Evo Chassis Kit refines front-wheel-drive performance for on-road competition. Based on proven FF architecture, the Evo adds chassis and suspension upgrades that let experienced drivers dial in stability and steering feel. The kit focuses on a stiff yet light carbon fiber structure and race-capable suspension components.

Stiff Double-Deck Carbon Structure

The chassis uses a 2.5mm lower carbon deck and a 2.0mm upper deck to hold rigidity while keeping mass down. The suspension borrows geometry from the TRF418 series to provide fully independent double wishbones for stable tyre contact. A sealed oil-filled gear differential in an XV-01 inspired gearbox smooths power delivery and helps maintain traction in corners.

Component Quality and Drive Efficiency

Included parts are selected to improve reliability and setup accuracy. The TRF dampers with a hard black coating help control body roll, aluminum turnbuckle shafts offer durable alignment control, and fluorine-sealed ball bearings cut drivetrain resistance. Double cardan driveshafts reduce slip and sharpen throttle response.

The Tamiya 84394 FF-04 Evo is aimed at seasoned RC racers who want a light, stiff FWD base that responds well to setup tweaks and upgrades.
