Should it be a problem,you can always do a small,vertical, 'step' backlight which is inset into the rear slope.It doesn't have to be very large and the recessed area around it will simply capture a vortex of which the outer flow will just skip over.Many supercars and competition race cars have used this when running proper K-Form rooflines.
Thanks for pointing that out! I'm going to take it one step further, and tell me if I'm off base here. What would happen if I ditch the Lexan entirely and leave the rear window and trunk lid uncovered, with the tail coming up the sides to the roof and then everything past the trunklid built up to the template? Essentially, a larger cutout inset in the slope? Is there a maximum size where that will start to impact the airflow?
