The 3Racing BDY-F113 is developed for competitive use on the F109 chassis and identified as the JLB03 Type A variant. The profile concentrates on airflow management to reduce turbulent wake and enhance high speed stability. Polycarbonate construction keeps mass low while providing impact tolerance suited to racing environments.
Contours and cut lines are located to influence pressure distribution and minimise aerodynamic disturbance. On-track this can translate to improved top speed and more stable behaviour in high speed sections, supporting setup changes aimed at reducing understeer or oversteer.
Mounting points are factory-drilled to align with the F109 chassis datum, enabling repeatable installation and consistent body position across sessions. This consistency helps reduce variables when fine tuning suspension and aero balance.
