Massive cardboard air dam on Geo Metro, A-B-A coastdown test

Did some CAD work today (Cardboard Aided Design).



For fun, vote on what you think will happen with this massive cardboard air dam in A-B-A testing....

1) Reduced drag vs. normal grille block
2) Increased drag vs. normal grille block
3) No significant change
4) AAAAAHHH! MY EYES!!

(Multiple answers permitted.)

Notes:

1) Same size openings for cooling air in the grille block vs. air dam.

2) There's just over 8 cm / 3 inches of clearance

3) I angled it slightly to lower the stagnation point

4) the floor of the car has about 15 cm / 6 inches of clearance

5) the lowest suspension points have approx 12 cm / 4.7 inches of clearance







Compared to stock height/angles:
