My wife was at the track this weekend. She is ridiculously fast. I don't know what her trick is. She just keeps getting better and better.
Actually, I do know her trick. She learns the track, before worrying about going fast. I'm just not patient enough for that. I should learn from her.
This weekend, as she was passing everyone, a couple of instructors commented to their students about how fast she was. One of the students came and found her, to tell her about it. He also said "you were smoking your tires through those corners!"
I told her she needed a limited slip diff, and explained why.
"Nah" she said, "I can still see a lot more places where I can pick up more speed."
So, take that for whatever little it is worth. I think she might have liked hearing that she was putting on a show, as she left people behind. :-)
