Exploding discs kill,simple as that.
Have a look above the bar in the Piston Klause for a segment of 993 disc!!
I recently inspected a disc,which was close to the outside of the disc,and advised marginal/ready to bin.After next 20 min session,the disc had split all the way to to the edge,and produced a 1mm step in the disc surface.
Saying this it was on a race porsche with aggresive braking.
Porsche always used to advise to replace the discs when any one hole had split to another hole,sounds like they are on the side of caution now also.
