The bigger rotor is apparent enough.
Anyone know for sure?

They are NOT the same.
Boy, this thread sure degenerated pretty quickly. The need for bigger/larger brakes depends on the usage. A 3.4L has 50% more power than a 2.5L and will generate speed a lot faster. If you are over-heating the stock brakes, then you are perfectly justified in putting in bigger brakes. I presume the poster that put in a 3.4L did so because he drives "enthusiastically". The difference in weight between base and S is minor. Going to 350mm GT3 brakes is another story however which is why Porsche offers PCCB in that size.
Contrary to what most people think, IMHO, upgrading the fronts without the rears is a mistake. The problem is that by enlarging the fronts, you increase front brake bias. The cars already have heavy front brake bias. There are significant gains to be had with shifting brake bias to the rear.
