Hot Rod Magazine (I think) did some wind tunnel testing on a second gen Camaro land speed racer and found that lowering the car in any way-front, back or all around- was beneficial (this may have been from Hucho, but both are useful sources). Your sloping roofline probably acts like a very mild kammback right now, recovering pressure built up by the front of the car, and as long as you have an air dam to deal with air aimed at the underbody, you should be fine.
