:icon_neut i dont get what your saying...all you see on the track and race cars are drilled/slotted rotors? Are you saying they work better but wear quicker?
Have you EVER seen a professional racecar (F1, Champ, Rally, Nascar, LeMans, etc.) with drilled rotors? I haven't. A lot of them come with slotted rotors, which works really well for high temp racing applications.
If the holes are casted in, such as Porsche or some Brembos, then it MIGHT stand up to a couple hot laps on a track. But drill-press drilled rotors like the R1s will crack.
Go to a performance car forum, such as Z06 or BMW forums, you'll see that no one run drilled rotors on the track.
