When air goes underneath the car and there are gaps it creates turbulence from the air getting trapped in those gaps which affects top speed and cornering (in road cars fuel economy). When the floor is flat the air gets pushed straight to the rear eliminating that turbulence.
Also when air gets pushed underneath the car it gets pressurized; the lower the front the more pressure created, more downforce generated. So in racing terms a flat floor is more valuable than a huge rear wing.
I cant wait to drive a car at 180 on HSR to see if it pulls... hmm whats an M3 look like underneath. O.o
