I do think even with stock rotors .8g's under braking still leaves you room to brake harder as long as it's not downhill. I have the same setup stock rotors/calipers w/Ferodo pads and Motul fluid I can hit 1g under braking while going straight or uphill. Downhill depending on the speed is in that .8 -.9 range.

How much negative camber do you run? And how does the sound on your video not sound like wind? Do you have a mic on the back bumper?
I am maxed out at -3.2 camber. your guessed right, I have a separate mic taped to my bumper. lived with the wind noise for too long

On the back bumper or around the license plate somewhere?

Also, I'd recommend something like an AIM Solo for better data acquisition.

I tape it up on the middle of the bumper and a little towards the middle. one time I melted the gopro plastic when it was too close. that sh7t is hot! yeah would like to upgrade my data gear. adding the 5hz gps iphone thingy is a big improvement. forgot what's it called but aim solo is nice. you were saying because of my confusion with the seemingly contradictory results?

. the lap starts at 8:20

here's another video from the last session. I have edited down to the passes plus the last 7-8 min where I was chasing a turbo s for several laps. the guy didn't have brass balls to open it up. my car dies near the end with a limp mode
