I only get aggravated when people post bad tech for people who are generally curious.
I'd be interested in reading the paper if it wasn't paid. Though knowing some of GM's interactions with suppliers, I question their engineering from the ground up. I'd take nothing but an independent test without a grain of salt.
A healthy dose of skepticism is a good thing and I too don't like seeing bad tech posted.
I agree that other than the drag strip or autocross course non-drilled rotors are the way to go, and in other cases any benefit from drilling isn't monumental.
If anyone is in doubt you really can't go bad with the blanks. If you like the looks of drilled and aren't going to be repeatedly hitting the brakes hard then quality drilled rotors are fine - in my opinion of course!
The illusion of speed is a helluva thing, isn't it?
Gotta justify that $75,000 price tag somehow. Might as well make them look the part.
Except it's those cars that will see hard brake use. Autobahns work cars a lot harder than interstates. And in spite of generally excellent driving by the Germans, you will need to make hard brake applications from north of 3 figures when some tourist, totally unused to the speed, decides to suddenly go into the left lane. Heck, even carbon brake discs get drilled, but not slotted.
BTW, your argument against drilling could just as well be used against slots - both are there to get rid of the gasses that get generated under extreme conditions.
