The real question is......how much would a driver detect in the difference of the aero at that point? At normal (speed limit) speeds, probably none at all. At high speeds, it may be much more detectable.
No expert here. Just stating what the engineers were attempting to accomplish with the car.
That said.....if you ever plan on autocrossing your i8 or any other type of racing where constant stopping and starting is required, DEFINITELY change the size of the wheels.
