I was very happy with my EBC Yellow on the fast road driving and it seemed good at my first track day at the very demanding Istanbul Park F1 Circuit. But after 2 x 20 mins, my pads cracked which had probably only in total 5k kms. As I blamed the discs which probably also caused no good bedding, I'm now again with EBC Yellow and did 2 track days, one being rainy so slower and cooler rounds and second with tyres almost gone (as Trofeo R did not make it on time) for 20 mins but was enough to kill my front tyre.
I did a search on youtube and found this which seems Yellow was not the right choice for him for heavy track and his car weight/power ratio:
Reading above youtube video explanation, I checked below link:

After entering weight/HP for Gransport, selecting Track Driving & Race, option is Blue (which they still say it's good for road) and Orange for even more demanding situations. You need to read below if you want to go with Blue at least because it could cause issue with your insurance:

Below is the summary from EBC:
"For those driving higher performance vehicles <hard> on the road and occasionally on the track, a set of EBC YellowStuff is the best option and these pads also DO have R 90 approval and are therefore perfectly road legal. That leaves EBC’s ultra-performance Blue and OrangeStuff grades for drivers who push their vehicles to the limit on road or on track. These materials don’t have R 90 approval (apart from a small range of BlueStuff pads which do) but the levels of performance offered by these materials is undeniable."
As my track needs very good brakes to slow from 210 to 65 kmh, I will reconsider yellows after seeing if they cracked or flaking:
EBC has also new stuff coming soon. Maybe 4 pistons is not an improvement but they claim differently saying large is not better. Interesting note for yellows noting "for moderate track use". Not sure of course if they come for the size of 4200. As far as I know, FD is also working on upgraded lighter front brake kit.

Regarding experiences mentioned above:
BennyD: was your experience also for track use to compare DS2500 vs Yellows?
Panicracing: what was the bedding procedure for you for Yellows? I assume you didn't take them right to track. They need 300 kms or so city driving stop & go before and then some bedding hard slow downs. Also were they bedded to new discs or used ones?
I hear very good things on Pagids, the version they use track oriented Porsches. More expensive for sure but anyone with experience on Pagids vs Yellows? How about experiences with Carbon pads like from FD?
One last thing which I knew wrongly. Even though DOT 5.1 should have higher boiling point then DOT 4, this also depends on the ingredients also in the fluid and some DOT4 are better then other DOT 5.1:
This note from EBC again: .....kits are supplied with 1 litre of BF307+ super DOT 4 brake fluid. This fluid has a 307 degrees C boiling point, a significantly higher boiling point than standard DOT 5.1
Standart DOT 5.1 has 270 degrees C:
