[s-cars] Brake Rotor with Big Reds

[Theodore Chen]

posrche's rotors are more accurately described as "holey" than drilled.
those holes are cast into the rotor, not drilled, and the rotor is
designed with extra reinforcing structure to make up for the weakening
of the rotor caused by putting holes in it.

in a street application, it's for looks.  on race cars, it's more
functional but most of the 911 GT3s i saw running in ALMS at laguna seca
recently had slotted rotors with no holes in them.

also, race teams replace the rotors after every race (or every few races if
they don't have the budget).  are you prepared to do that?
