Erm.......right, in order from road to full race: EBC Greenstuf = "fast road" but I hate them, don't work until you get them hot then they suddenly get some bite, I kept locking one or other front wheel early! They also "feel soft" so you can't stand of the pedal as hard, might be an illusion due to them being lame when cold. EBC Redstuff = "very fast road / trackday", these are better from cold than the greens, withstand more abuse than the greens and are more predictable than the greens. For like 10% more, so don't bother with greens. We have a full race V8 TVR guy who runs Reds with slicks and has never overheated them. 99% of kits I sell to all sorts of people have Reds. EBC Yellowstuff = "full race", I havn't used them but lots and lots of my more serious trackday / silly BHP customers have, and they are better than Reds but take a bit more warming up. EBC Bluestuff = "full race endurance", long distance stuff, not applicable at all. Mintex = More expensive, like Ferodo but not as good value as EBC for the same spec. My suggestion is EBC Reds, not sure about the rear though as EBC don't seem to offer Reds for the back...?
