Have just had the opportunity for an extended DS3000 test at the Nurburgring, covering cca 700 km on track plus about 3000 km on the road.
The pads are surprisingly streetable, being quite responsive from cold and they are quite easy to modulate too. I was expecting a lot of noise, but it just did not materialise on my car (although there was another car in our group on DS 3000 where they proved very noisy).
Braking power is very good, but obviously the increased stopping power generates more heat, which in my case resulted in cracked front discs. I did do three consecutive hotlaps (75km) including the grand prix circuit for this to happen though, so perhaps more judicious use with more cooling time would have avoided this issue.
Wear rate is higher than with DS 2500, mine are now at 3-4 mm from 9mm at new, but this is again a function of the greater friction coefficient and not unexpected.
Final oft cited drawback of hot embers marking wheels was not a big issue for me, as my wheels are graphite coloured. For those who care a wash at the end of each track day should take care of it.
In summary, a great track day pad, which is far more streetable than you would expect. I have already ordered another set
