Those are stock rotors drilled and slotted in that manner. I wouldn't go with rotors that are drilled like that so closely together because with heat and time they may crack along the thinned section. Why don't you check out the R1 concept ones on ebay.

The holes and slots are just for looks and nothing more. For added brake performance, you'd need that $5000 brembo big brake kit
Here's a pic of the cracking I was talking about. Now imagine 4 holes drilled in parallel...
