I am a huge Ferodo fan. Not just of the DS2500 but also the DS1.11 and the DSUNO. Those are the 2 other compounds I have tried on the GT350. If you want to go a bit more aggressive on the compound, the DS1.11 are great. Better wear on the track and way less brake dust. No free lunches though. They are a bit harder on the rotors and require just a bit more temp to work well on the street. And they cost more. If you are doing serious track time, I would run the DS1.11 over the DS2500.
I have not run the new DS3.12 but they sound great as well.
