Interesting breakdown. Most of it is what I do except for two spots: The uphill esses (T3 and T3A) and the downhill esses (8 and 8A) out of the hairpin coming off the drag strip.Sonoma Quickstart for those interested. Details of the lap during the 2nd half of the video.
I tend to do a minor trail brake going into 3 and then coast into 3A. This allows me to carry more speed over the crest and not have the urge to hit the throttle hard. I also use the curb on the inside of 3A to help rotate the rear of the car.
At 8 I will trail brake into it and then blip the throttle at the apex allowing me to coast into the apex at 8A. Again, I will use the curbs to rotate the rear of the car.
The 'V" on hairpins works great as long as the corner allows for it. At Mid-Ohio I found that if I tried it at the keyhole the camber would send me too far off-line and I would lose time.
Good video overall.
