I have spent probably around 2 hours in total discussing brake options with EBC's technical guys.
Their opinion is that is u have standard front discs, then go green all the way around. If u have grooved front discs, it depends how u drive.
As our car is a bit heavier than most, the case for red stuffs is a bit stronger.
If u drive at over 80% for a lot of the time, like me, Cruise, or Stuart, then they don't hesitate to recommend Reds all around.
That said, the local Ferrari garage that I've been visiting to plan my next secret mod
swear by Tarox discs. Haven't discussed pads yet, but they also make the point that 4-pot calipers are more than enough.
According to them, the only advantage to a big brake conversion is the basic physics that the disc is being gripped further away from the wheel centre, therefore a greater net stopping effect.
track days
EBC were quite apologetic that they don't make blue or yellow stuff pads for our car. They say that for a serious track day, take along three or four sets of red stuff pads, and be prepared for regular changes. They quoted Castle Combe as one of the most demanding tracks. That said, they will custom make a set of blue stuff, their recommended grade for our car on the track for around £85 a pair.
