Brake Deflector Guide : Brake Duct : R32 GT-R : R34 GT-R : Brake Cooling

The R32 GT-R N1, R32 GT-R Vspec, R33 GT-R, and R34 GT-R all had brake deflectors to direct airflow to the brake rotors.  They also sported Brembo brake calipers.   In an ideal world, the Skyline GT-R would have had a trailing caliper, so that air could easier get to the center of the rotor, to be pumped out through the vanes, cooling the rotor itself.    On the street, this part, probably isn't important for you .  The the track, very important.

You can set that air deflector is doing its best to direct some air at the center of the rotor. However we have a caliper, a axle all in the way.

Supertec Racing aluminum air guide for R32/R33

There are also some other aftermarket options, like the above from Supertec. These are made from 2.1mm aluminum sheet so not to deflect or warp at high speed. Optimizes air flow to the brake discs for improved cooling over the smaller factory air guides. These are based on the R33 GTR LM design.
