x-drilled Vs. vented...or both???

[dgluyas]

I have got 944 discs at the rear that have been cross drilled and slotted.Some say it weakens the disc. I got mine done by a very reputable v8 racing car group and they heat treat the disc and do it properly. The disc they assured me would be fine. The gas slotting helps too in their opinion. Having driven the discs before and after the only comment I could make is that they look way cool!! I personally love the look of cross drilled slotted/ventillated discs. I have not had any problems with hard braking on this setup. Pad wear is fine.
