Up until 2003, NHRA and IHRA had the same 16 FWD classes (AF to HF, stick and auto). IHRA still uses this format. In 2004, NHRA decided to go to four FWD classes. AF to DF, with sticks and auto's run together (sticks carry a 100 pound weight penalty). A few years ago, they added a new A class, and what was A through D is now B through E. It totally obsoleted my old car that I drove for Billy Nees. What was an HF/SA, 18.60 Index, 2,510 pound minimum weight in the 27.5 pound class, became a DF/S (now EF/S), 17.75 Index (that is now 17.45), 2,295 pound min wt, in a 25 pound class.
But yes, 18.49 makes your car a DF/SA in IHRA on a 15.60 Index, and it's an NHRA CF/S on a 15.15 Index.
