Like everyone else, i'm going from what iv'e heard from others..
If you go with ECS tunnings Porsche brakes, (the ones you pictured), they say there made for just that... Porsches. Our master cylinder can't use push those calipers to there max. The'll work, but in time your master might blow out trying to push those calipers (iv'e never know anyone to acualy blow there's, but again, what iv'e been told by many people a psiblity of what can happen).
Companies like brembo, and Stop Tech took this into mind,and made there big brake upgrades especificaly for our MC. So from a perfomance stand point, they might be a better chioce, but if you want the ultamate "wow" factor, then the Porsche brakes are the chioce!!
