case 1: roof off and windows down, the spoilers still work pretty much as usual but total drag goes way up, this is the worst case scenario
case 2: roof off w/ windows up drag goes way down, not as low as all closed up but not too bad either, spoilers function as usual
case3: roof on w/ windows down drag is higher than all closed up, somewhere in between case 1 & 2. A similar thing happens w/ coupes w/ windows down, drag goes up and spoilers work as usual
