What exactly do you mean that the bike lifted a little when they scraped? The pegs should move up as they hit the pavement to not let that happen, unless maybe as a reaction to feeling it scraping you lifted a little, I know I've done that before I took the feelers off. The first few times I felt them scrape it startled me a bit and as a reaction I lifted off my line and ended up running wider like you described. As I got better at taking turns I took the feelers off my pegs and I use my boots as my "feelers" now.
But +1 on what everyone else is saying about body position, as you get better you will find yourself taking turns faster at less angle.
Maybe it was the center stand???
