From my experience... all EBC pads are useless for road use ! i had yellow stuff pads and black diamond discs in my first 600 turbo, great if you get um hot... put you through the windscreen good ! But i managed to get break fade with them coming down a mountain road in Scotland so not great... and for normal driveing they just were not very effective.
My latest 600 turbo has the ebay upgrade on it, grooved discs and redstuff pads, they are rubbish lol, i can honestly say my current car with unipart discs and delphi pads is by far the better setup for everyday driveing, depends what you are useing the car for really, cant go far wrong with OE stuff if you not upgradeing the size of the whole setup really.
Oh i had EBC Greenstuff pads in a Golf Vr6, they where fine actually 🙂
