I have had at least two sets delaminate on OG 9-5's - on road cars I have tended to use Pagid (Mintex)
On the NG 9-5's this car arrived with one delaminated, and to get me through the MOT just chucked in one of the spares from the petrol NG. The disc was a little damaged already, because of the failure, so perhaps it was more grabby than usual, but not enough to show on the rollers.
I one tried EBC Greenstuff as an alternative to Mintex M144 (yes, that long ago). They were not as good, suffered from fade and apparently caused terror in the EBC technical department when they got to hear the application I had tried them on....
