The 3Racing F104-07/15/FG 1.5mm T-Bar is produced to support controlled chassis flex characteristics on the Tamiya F104 layout. Its section and thickness provide a defined compliance point that interacts predictably with toe, camber and roll stiffness adjustments. For setup changes, log baseline telemetry or lap splits before and after fitting to quantify the effect. The part is manufactured to withstand repeated race use while maintaining dimensional stability for consistent tuning sessions.
