![Question](https://rennlist.com/forums/images/icons/icon5.gif)
The brakes on a 911 are mounted toward the "center" of the car, but the Panamera calipers are mounted toward the "ends" of the car.
Does anyone know why? Just curious about the different locations.

Probably has to do with the suspension and room.
Those wheels on that Panamara really make it look nice though.

perhaps weight distribution?

Weight distribution, lowering center of gravity, clearance, cooling, etc. are all things that need to be considered for caliper placement. My guess is that on the rear biased 911, getting weight toward the center of the car is more critical than on a heavier car like the Panamera that already has closer to 50/50 distribution. Suspension design is also different between the cars and might be a factor. Another item that needs to be considered; maybe airflow under/over the Panamera is such that the calipers get better cooling where they are positioned.
Wish we had a for-real Porsche/Weissach engineering/design insider who contributed to the forum and could answer these kind of questions authoritatively!

Mike, thanks for the comments and the extended reasoning about the comments. I was also thinking it might involve weight distribution, but wanted to hear what others thought about the different placement of the calipers.
I agree, it would be nice to hear the engineering/design reasons from someone at Porsche.

I know when I was getting the "old 996 4S", the center mounted brake calipers were said to be a function of cooling as the ducts channelling air from the front of the car into the wheel well were deliberately designed for this. Guess location also works for weight distribution. On the Panamera, firstly, I think one needs to ask where the Cayenne brakes are mounted as the system was I thought taken over from that. Then, the answer may have something to do with suspension and front drive shafts....

The Cayenne has a different caliper layout than either the Carrera or Panamera; both front and rear calipers are fixed at the leading edge of the disc.

I look at the calendar......nope its not April Fools Day.
I don't know the answer, but I do know the caliper location has nothing to do with weight distribution or "polar moment reasons".......
Somebody start a thread about why the seat belt buckles are located in the cabin beside the seats.

Next time I will post a question which is much easier to answer, like..... "What's the meaning of life?"
