Summary

  • Diffuser
    • Diffuser End 20mm Higher
      • The front and rear downforces increase without increase of drag and these bring an Improve ment of L/D
    • Diffuser Vertical Fins
      • In these simulations these fins were not advantageous
  • Rr Bumper B
    • Slightly increases the front downforce and decreases the rear downforce without the drag change
  • Rr Bonnet Horizontal Vane
    • Slightly increases the front downforce and decreases the rear downforce without the drag change
  • Side Mirror
    • Side Mirrorless
      • ‘Side Mirror’ decreases the front downforce or increases the front lift force
      • ‘Side Mirror’ seems bending the flow downward and generating the lift force
    • Side Mirror 30mm Highter / 20mm Outer
      • Slightly decreases the front and rear downforces without the drag changes
  • Rr Wing
    • Main Plane 1pc Z+50mm
      • Increases the rear downforce and decreases the front downforce
      • Increases the drag slightly
    • Two Pieces - Main Plane 1.4 / Flap 1.3 32.7deg
      • Generates much larger rear downforce
      • Distribution of downforce is too far backward
      • At ‘Control’ angle it seems a flow separation appears on the main plane
    • Two Pieces - Main Plane 1.4 / Flap 1.3 27.7deg
      • Lower drag and lower downforces
    • Two Pieces and Lower Front Ride Height
      • Distribution of downforce is towards front
