Hi there Nero.
A couple of months ago i've installed a full set of Yellowsuff pads at front & rear.
About dist i installed EBC 3GD disc on front and OEM Renault disc at rear.
Breaking seems good at cold and seemd to get better and better when they get warm & hot.
I have not yet drive on track, but i do a lot of mountain roads and the braking difference between standard brake setup and EBC Yellowstuff setup seems very good.
And at last but not less important... price!, Yellowstuff are not that expensive as DS2500 or Carbone Loraine and has a great performance.
Just another thing, yellowstuff pads dust like crazy! (i think this is a common thing on track oriented pads).
And the 65 pounds price is very good.
