I think it was COramprat that said:
"I work at a major airport and I see huge planes every day. If drilled and slotted was so good, then why aren't airplanes using the technology?"
How often do airplanes have to stop? I dont see many Jets hitting the brakes every 30 seconds before they enter a corner! They hardly have to worry about brake fade!!
Ask yourself why supercars use drilled or slotted rotors...? Thats a little more relevant.
Porsche Carrera GT or Ferrari 599 for example.
