FYI, I had my track day 2 weeks ago. It was amazing. My car did suprise me.
My instructor was telling me to turn sharper. I felt like I was turning as sharp as possible at 60mph without spinning out or losing control. He grabbed my steering wheel and forcefully turned it. No tire screeching. No loss of control. It took that turn like a champ.
I shaved off at least 33 seconds off my laptime from my first ever lap to my last recorded lap about 5 or 6 laps later. My camera ran out of memory.
I had a few laps after my memory ran out so I assume I shaved off more time. Every lap was faster. Here is a video of the faster, last recorded laps if you have not seen it.
