inside the boot

My thoughts are that it may be beneficial as the very low pressure at the rear could be 'fed' from the wheel arches.

Also a lot of race cars now use vents rear of the front wheels, this would be a vent at the rear of the rear wheels.
*The rear of the wheelhouse is almost to the back of the car,so the pressures would be very similar and might not induce any flow if you opened up a channel.
*Also,the turbulence behind the back of the rear tires is already part of the wake which would really frustrate any induced flow.
*Ducting air inside the body would itself induce surface friction.
*The Ferrari 599XX race car does use ducting,but uses dual,high -static- pressure blowers to induce pulsed flow out the taillight openings.They claim that they can detach the wake this way.
