Why crossed drilled rotors are not the best option

[ephesiangts]

happens even if its not cross drilled.

Those must have been coping a heap of abuse!? Either that, or they were sh!t quality to begin with.

[smythie]

my guess going by the surface cracks is that it copped similar abuse to the first one posted.

I had a similar thing happen years ago in my old VL turbo. I had a set od DBA discs with the holes and cracked them both at 180kph!! Never bought them again. When I had my rex I bought a set of slotted only DBA 4000 and they worked great. Never had a problem with those discs. I think with the ones on the VL I had were purely to look good but were utter shit.

Even when the discs go on my Liberty I would replace them with the DBA 4000 slotted again.

Factory brembo drilled rotors are fine.

The hint is where the cross drilling happens (along the vanes) not in open ventilation voidspace.

Full face discs are the best bet and are quietest, unless you specifically need slotted rotors (hardcore abuse in the rain, massive pad gassing at the track with full face rotors, or you like to look in the mirror a lot).
