I did a 2 day tracquest event at Laguna...Sergio's right about the single and double apex...most of the students were single apexing that turn, but you can see why that's not done in a race, because the inside would be wide open for a pass. From what I remember you need to go very deep before starting your turn...so I agree with Sergio that he began the turn too early and early apexed, also with too much steering input...he needed to straighten out the wheel sooner than he did at the end of the turn. I think his high entry speed scared him and that caused him to turn in too early. He could have bled off more speed by waiting to begin the turn in and staying on the brakes, thus giving him a better angle for the apex. That's an excellent and safe corner to practice throttle steering as well. I really had a lot of fun using the throttle to get the car turned so I could be hard on the throttle right at the apex.
