Tamiya F104 Steering T-Bar 1.8mm Fine-Tune (F104-07/18/FG) by 3Racing  [F104-07/18/FG]

How the F104 T-bar alters steering and setup notes

This T-bar is an RC-scale hop-up for the Tamiya F104 chassis, offered as model F104-07/18/FG by 3Racing. It is a direct replacement that modifies lateral stiffness at the front to change steering feel and the initial turn-in characteristic while keeping suspension geometry intact.

In practice, selecting the 1.8mm bar increases front stiffness relative to thinner options, helping to remove flex and deliver a more immediate steering response. Expect modest tuning effects: this component is intended to be combined with other small setup changes to tune the balance for carpet or asphalt club racing.

Installation follows standard kit procedures: remove the factory T-bar, locate this unit on the original mount points and check servo and steering clearance before final assembly. Because some F104 kit variants and previous mods alter fitment, confirm alignment and test steering movement gently on the bench to avoid binding.
