Utenigma,
That is not the line through 7-8. I know many people teach it, but it just is not the line. Look at the rubber marks on track out of 7 and entry braking into 8. They tell the story. Start right at entry to 7, turn in to clip the apex of 7 at full throttle. If done right, it will push you out to the tire marks at track out. Ride the right side into 8 and brake hard to hug the inside edge over the apex. 8 is a throw away. Carry the speed thru 6-7. Then back on full gas thru 9 until 11. All that arcing for 8 is not the quickest line unless you are a miata.
