When Pontiac chose this style of spoiler for their Trans AM Firebird they knew it didn't work as well for drag reduction as a simple 'flip-up' spoiler as on the Camaro.
But you do get better visibility when backing and they'll clear off snow better.
Without a wind tunnel it's going to be tough to outguess Toyota.
