I didn't say it in my youtube comment, because I was only interested in the message to you and who am I to tell Sam what to do..... But

.... I felt if he used more trail braking or some left foot braking to get the rear to help a bit more then he would have found the rotation he was seeking. Just my opinion but I have seen that play out with our car.
As you said, a bit of fine tuning of suspension and mapping to suit that track and he would find some big time gains.
STI fans can be so precious because STI's aren't the car they once were, it's sad but they need to face facts. I'll be the same in 2 generations of i20Ns if they're still around I think.
