I don't have exact numbers about how long they last, but I've heard positive things in this matter. It depends if you track them and how you drive. From what I read till now, they would last almost as long as a normal sport tire. I am not yet sure if they have so much profile depth when new.
Corsa sys has 8/32" tread depth
PS2 9,5/32" and 8,5/32"

That would be great!
