This 1.5mm T-bar is a tuning component for the Tamiya F104 chassis that defines the front cross-member thickness to modify front-end stiffness. As a structural element it affects how loads move through the front during cornering and throttle changes, giving a direct way to adjust steering characteristics without changing suspension geometry.
Compatibility is focused on the F104 family as stated in the product name; verify your front bulkhead and mounting points before fitting. Installation replaces the factory T-bar at the same mounting locations on the F104 front assembly to achieve the targeted flex behaviour.
Tuning note: using a different T-bar thickness alters transient steering response and the initial bite in corners. Use this part in concert with shock, anti-roll bar and tyre adjustments and change one item at a time for clear comparison.
