evening chaps

didnt really know where to post this as the car is several vehicles in one

the orange mk2 vr6 is running the Ibiza sport 16v 280mm brake setup with greenstuff pads and grooved discs, and a G60 master cylinder. It stops very well except when slowing down from speed, i.e. the pads fade oh so quickly!

I did a search but 'greenstuff' comes up several times... Have you guys got any other brake pad suggestions?
Car is only being used on the road, i.e. no track days
