Code 171: With Speed F/X Package: Aerodynamic system consisting of a 'Wicker Bill' and 'Downforce Chime' that works in conjunction with Simpson's built-in BLD (Boundary Layer Design) and Gill vents to add helmet stability at high velocities in open cockpit cars.

  • Aerodynamic full 'Wicker Bill' follows the helmet's natural contour and projects into the airflow just behind the crown of the helmet. The result is increased downforce created as the airflow increases.
  • The 'Downforce Chime' is an extension at the base of the chinbar that captures the air that hits the front of the helmet (forehead down) as it flows downward toward the chin. This airflow hits the valence and 'pushes' the helmet down, counteracting lift.
  • Both aerodynamic 'Wicker Bill' and the 'Downforce Chime' work with the helmet's built-in 'Trip Strips' and 'Gill Vents' to stabilize the helmet ride in all conditions.
  • Build time for custom options: 7-10 days
  • For size see chart
