"I believe" what might be met by "Karting Track" is the standard normal pit area for drag racing (having done it myself) is the semi paved crisscrossed area inside of turn 8
Yes they used to run karts there that is what that pavement was put down for back in the day. Yes I know this shows my age, but then I competed in the High School Drags from 1974-1976.
The "new" cart track as Lance stated in the pit is only partly paved and too far away to be of any use for pitting for drag racing.
Then again I could be wrong, your mileage may vary, my opinion my not be yours, do not attempt this at home, for trained professionals only, no return without prior approval, not responsible for damage.
