Cool vids man!
3 things come to mind right off the bat. 1, on street tires, all you need is a really short hop to clean the tires off, any more than that and they get squirmy, especially 555's. 2, on that first run, you staged about a foot and a half to the right of the groove. And 3, mounting your go-pro facing the rear of the car brings a whole new world of wind noise!
But those were some damn good runs, and not terrible 60' for street tires. A good set of DR's and you're mid to low 12's all day long.
