I was wondering this when I was at a track last weekend, do you want to be on the "shiny" part or the dull, bare looking part in the center that appears to be where everyone else is (including this car)? Is that the groove? Seems like the shiny part might be still-sticky VHT? Help this drag racing amateur out!
