Greenstuff are not good, unless you drive slower than your granny!!
Redstuff are ace as is yellowstuff, used both reds dusty yellows not, I take the anti squeal pads off the rear of my yellows and have not heard a peep from them in over 15 years using ebc.
I've also used the "no feel" ds range, hate them with a passion personally, but that's the point brakes are a personal thing.
Anyone who believes ebc compounds are all the same should actually try USING them to see the difference not just listening to people with vested interests in selling other makes.
Police use them extensively(yellows) on thier traffic cars, as they are police approved, unlike ferrodo.
