Not sure yrs truly needs to refer to the rule book to clarify louvers in hood side panels.
Have a personal experience with one St Roadster who had set several records with small (3-4") louvers & made new panels with 6' ones and picked up 4MPH . Nobody protested the car before or after.
DECK lid louvers in STR? NoNONONONONO!
We witnessed that AMERICAN AUSTIN'S (Not a Bantam!) run Sunday and for all you TECHNOCRITICS methinks there should be allowances for COOL, QUIRKY, stuff!
And I'm not a Lattin fan!
