Brake pad fade
After a couple good sessions today noticed significant loss of bite when braking after about 10 minutes on track. The first ten minutes plenty of bite and then they went numb. 991 GT3 pads never seemed to suffer to this degree. I also noticed on Suncoasts site they list a new Performance Pad set, are these from Porsche? Has anyone used them yet?

I am guessing the pads used during the reviews are different than what comes on the car in the US. Shame on you Porsche!!!!!

Was this by any chance on basically new pads? If you haven't driven in anger or bedded the brakes yet, you may have experienced "green fade" or degassing of the pads. When you are bedding brakes, what you just described (along with a stinky smell) are a sign you got them heated up enough to degas. Let them cool by driving a few miles without using brakes, let them cool 24 hours, and they should be good to go. Otherwise, perhaps you boiled your fluid?

I had done 4-5 sessions previously over two days before this, albeit at slower speed. Yesterday was my first day pushing hard. I don't think it was fluid as the pedal wasn't mushy, it was hard, just no bite. Degassing is possible. Will be curious to hear what Disden says after next weekend.
I'm still surprised to see the "Porsche Performance Pads" available and only as a set. It does make me think they changed compounds from the 991 pads which were very good.

Interesting that they might have gone with a less aggressive, track ready compound this time around. Seems implied with that sport pad option.
Running fluid + RSL1 + Girodisc and I think the improvement on the stock 991.2 system is barely perceptible over the course of a session.
