I think what it is, the vents are on all cars, all cars vent the brakes and radiator. But the Z51 adds the electronic limited slip diff, so to vent this on the passenger side they added a vent and then they probably added one on the driver's side to make it uniform. All cars still use vents, the Z51 pack just uses more. Either way the brake cooling and radiator cooling is the most important part, the rest is gravy.
