What is the "perfect" 15x8?

Found these 15x8 ´Alpina reps for sale on another forum. Must be a new offering, because i´ve never run across them before.





I don´t like 15´s but these could sway me.

8x15 et 15 made by Performa, 600€ a set. That´s all i know.
I´ve looked for the manufacturer site but i can´t find it.

I´ve been humming and hawing over these since i first saw them, but wonder if ´15´s will look too small.
