This aftermarket hop-up is specified for the Tamiya F104 chassis under part number F104-08/18/FG. The 1.8mm single-piece T-bar is intended to give racers a repeatable method to increase front torsional stiffness and refine steering response without changing suspension geometry.
Compatibility is targeted at standard Tamiya F104 layouts; confirm mount alignment before fitting. The component replaces the factory T-bar at the original mounting points and alters front load transfer characteristics during cornering and quick direction changes.
Assembly notes: remove the stock T-bar and install this unit with the original hardware and hex drivers. For setup, use incremental on-track tests to quantify steering changes and pair the T-bar selection with small damper or toe adjustments to reach the desired handling balance.
