burning brakes smell, brake fade.. NO BRAKES.. need advise

they also cast the holes in rotor so the material isnt weakened by the x-drilling

Porsche's holes are drilled also - there isnt a longevity benefit over cast in holes over the drilled holes, provided they are both properly chamfered to relieve stress I dont think.

if you drill into something, its gonna be weaker where the material has been worn away as opposed to forming them during the casting process. now this may be negligible in the rotor application, but the nature of drilling is making the material fail in a very localized spot.
