Anyone drilled rotors for better braking?

At the track you will see nothing unless you have a very serious track car that can make use of them.

And sometimes then, the difference you see is a lot of cracking. As Xstream_1 noted, it's really just a weight saving measure, and not a good choice for a track car but can make sense for drag applications or motorcycles.
