Drilled rotors on ws6 store
anybody have any experience with these?
Chances are also is that they are actually drilled rotors as opposed to as-cast. As-cast "drilled" rotors are cast with the holes in the mold, making the rotor MUCH stronger and less prone to warpage. Cheaper brands of rotors will take a blank and drill the holes after the metal has been poured. This invites stress-fractures and increases the chance of warping.

Cast in holes are a MYTH, one of the aftermarket brake companies has a bounty out on cast in holes, nobody has collected yet.
Drilled is much more prone to cracking. Leave it to applications where rotors are disposable or where rotating weight is a concern. In this application removing mass from the rotor would be a bad thing. Rotors have to store heat during braking and then dissapaite after, remove material and the same amount of heat has less mass to absorb it meaning it gets hotter.
The outgassing excuse given for why this is supposed to be a good idea is a long outdates issue, not a current concern.
