All .. Super Classes 8.90 9.90 10.90 and Top Dragster/ Top Sportsman classes do need a SFI diaper, and on top of that any advanced ET cars running faster then 7.49 1/4 & 4.49 1/8th does need a SFI diaper also...
David,
That is not correct. They only require an NHRA APPROVED diaper. The SFI is not rquired until you for TA/D or better. The only place that I know requires the SFI approved diaper for 9.99 and faster is Norwalk for Super Pro and Comp.
