I was shooting in manual when I all of these photos -I couldn't even rely on the camera autofocus (since the objects were moving so quickly through the frame), so I manually focused everything as well.
My shutter speed was about 1/150-1/200, depending on the picture I was taken.
I did use strobes to help light the picture which in turn helped to freeze action and give the high key look
