The DS 2500 is so I'm told by others a good pad, I think pads and brake feel are a very personal thing, you may love them, you may love another make.
I currently have a set of unused DS2500 pads for Tarox B32-6 calipers, I get ferodo free, but instead have bought EBC Yellowstuff.
Don't get me wrong the DS 2500 isn't a bad pad by any means, once up to temp, and if you like zero feel through the pedal, but there are better imo, ds is streets ahead of std pads though, except cold performance.
