I have now been on 2 different Porsche UK training days, and have had chance to ask three different people the question.

In my time of driving PCCB I felt very little difference. The pedal felt harder but performance seemed pretty much unchanged (fade was not relevant in what we were doing).

Each and every one of the three had the same opinion that PCCB's make very little difference in normal driving. And short of pedal feel you would find it hard to spot the difference. They all agreed that (excluding fade) in stopping terms there is really nothing in it.

As for the weight. Not one of them could really notice the difference that the weight saving made.

Seems a lot of money to save a bit of brake dust. And note .. these people are Porsche trained, employed and very experienced in 911's. Most of them with motorsport backgrounds.

If they can't feel it. What chance do I have!

Cheers,
