Tracked it tonight.
These brakes stop. And they stop. And they stop. No brake fade, and they are just the supplied pads from Brembo, which if I remember correctly they are similar, but not the same, to the Ferrodo DS2500. I wasn't doing any 100 - 20 stopping, but a lot of aggressive 60-30ish braking, constantly.
Every time I pressed the pedal it felt like the harder / further I mashed on it, the more the car would stop. No ABS pulsating, not stiff pedal, it just stopped.
I did turn off traction control through the button, and did see the light come on a few times, but when I was really on the car I got it sideways for a bit, didn't really feel like the computers were taking control, I had enough time to react to it.
The suspension feels great, car stays flat, and just goes. Really looking forward to an performance Haldex controller, and rsb. Just need to sort out the stage 2+ first
For any socal people, I ran it at Adams Motorsports Park in Riverside, fastest time of the night was a 50.13... (Which is not too bad for not being there for a year, and not tracking this car yet) All of my runs were pretty consistent with a passenger, I am sure with a little more time and just going solo I could break the 49s, without changing anything else on the car.
