This is an RC-scale replacement hop-up part for the Tamiya F104 chassis supplied by 3Racing, listed under part number F104-08/18/FG. The one-piece T-bar with 1.8mm thickness is intended for use where riders need a straightforward method to alter front-end stiffness and steering response without changing other suspension geometry.
Compatibility is specific to the Tamiya F104 series chassis; confirm fitment against your chassis layout before installation. The part installs at the same mounting points as the factory T-bar and functions as a direct swap to influence how the front of the car transfers load during cornering and direction changes.
Installation notes: remove the original T-bar and fit this one-piece unit using the existing hardware and standard hex drivers. After fitting, perform incremental tests on track to evaluate changes in steering feel and balance, and combine with incremental adjustments to toe, camber, or roll center if needed for finer tuning.
