What I can't figure out is their reasoning. Why is there a gap between the sections? I mean, obviously they want to let some air between the tire and the engine cradle. But why? Again, this is a Impala, not a Corvette. I don't really get the brakes that hot (usually) that they need inboard cooling.
And while you are pondering that riddle, why on earth are they terminating the curved outboard sections 2/3rds. inboard from the outside of the tire??? If I was doing it (before I saw this) I would have extended those outboard sections so they flow the air around the outside of the steering tires. Not slam right into them at 1/3 from the inside. ???????

Also note the center portion is not below the aluminum cross member. I believe the reason for this is so that it will clear most parking stops. It is the same configuration used on my 06 Grand Prix.
Now.
