Cayenne Turbo Powerkit Brake - Experience (High Speed-Heat)
Over the past few days, I had the chance to drive my CT with PK for a few couple of hundreds of kilometers on the Auotobahn. We have pretty high temperatures right now over here in Bavaria, up to 35*C and very sunny.
The powerkit brake works incredibly good, no sign of heat fatigue, rubbing or whatever, even at very hard braking attempts from 270 kph to 120 kph for example.
I even don't have to fully apply the brake, usually around 70% of braking power is needed to achieve excellent braking results.
My brake discs are already "blue" now (you can imagine the "stress") but they keep up very good.
Overall, I'm very satisfied and impressed. My "old" brake started to rub badly at those speeds and braking performance was getting worse and worse, resulting in almost no braking power at all after some hard high speed Autobahn driving on very hot days.
For safety reasons, I wish Porsche would stand up to their history and their reputation and offer the brake on ALL Cayenne Turbo. It is pretty surprising that the original CT brake is THAT weak in my opinion, maybe the engineers responsible for development should really get a few kicks in the...
But maybe it isn't their fault, maybe it is a question of money. Very disappointing.

Never got technical details about testing results, etc., nothing. 
I'm afraid 90% of the Cayenne customers don't even drive a little bit close to the limit. So there are no complaints about brakes, throttle hesitation or weird shifting behavior.
Dadgummit, we need one of those fancy highways over here.
