ELECTRONICS

AERODYNAMICS

System concept: high downforce at max. efficiency, easiest disassembly and assembly of each wing, curve-optimized
Front wing: adjustability of the overall wing in height, finest aerodynamic balance adjustment via flaps
Rear wing: adjustability via CFK rods, drag reduction system for minimal air resistance on the straight
Side wing: Optimized flow around the tires, downforce via integrated wings
Thermal Management: Two sidepods with both external and internal airflow
