Well, i'm wondering if the directional vanes are mostly found on the really high end rotors. The 'performance' rotors I ordered that were constructed by R1Concepts (zinc plated, cross drilled and slotted) in fact use radial/straight vanes and NOT directional. Don't get me wrong, with the PosiQuiet Ceramic pads, this setup works SUPER. Drilled and slotted rotors: This type of brake disc is the combination of both the drilled and the slotted rotors. This type of rotors is designed to offer the benefits of both the drilled brake rotors and the slotted brake rotors. And these braking rotors design will combine both slots and holes on the rotor’s surface.

Brake rotors come in a number of flavors. You often see them vented, drilled, or slotted. Sometimes there's a combination of the three, and it's best to know which works most efficiently for the driving you plan to do. We know one of the biggest enemies of brake performance is heat, so the goal for any of these choices should be cooling your brakes to keep them from fading.
Jason Fenske from Engineering Explained is here to help you decide what kind of brake rotors you should choose.

Most brakes are of the vented variety. These vents help move heat along and keep your brakes in the proper temperature range they prefer to mitigate fading.
Alternatively, you might see drilled rotors on some high-end sports cars. You won't see these rotors on race cars though, as the drilled rotors can become stressed and damaged during the high-stress environment of racing. The reason you see drilled rotors on some sports cars? Honestly, it's because people think they look cool.

Slotted rotors are better for actual heavy-duty performance applications. They're stronger than drilled rotors, and they provide some other advantages as well, such as additional biting surfaces.

The number one question we are asked at DBA USA is, “Can your rotors be turned or machined?”
The easy answer is yes, they can. Somewhere along the way, someone started saying that slotted rotors couldn’t be turned. This incorrect statement has become fact, or at least urban legend, so we wanted to try to clear up this misconception. If done properly, and with care, slotted and drilled rotors can be machined. Not all warped, worn or damaged rotors can be brought back from the dead, but more often than not, a proper machining job can breathe new life to your rotors and should be considered a viable alternative to replacement rotors in some cases.
