I'm about to take a 1500 mile trip... mostly freeway miles at speeds between 70 & 80 mph. Gas mileage is an issue and i'm wondering if closing the rear spoiler, say at 80 mph, is possible and if possible does it significantly affect handling and will it improve gas mileage by reducing drag.Thanks,Bill Johnston, Baltimore
