By the NHRA rules I’m required to have SFI 16.1 seat belts in my full-bodied car that runs 11.20 in the 1/4-mile. Is the crotch strap belt still required if I have OEM seat?

Seat Belt Suzy,
Yes it is. In the 2012 NHRA Rulebook on page 40 of the General Regulations it states “A quick-release 3-inch drivers restraint system, with a 2-inch crotch strap, meeting SFI 16.1 is mandatory in all cars in competition required by the rules to have a roll bar or roll cage.” In the photo on page 40 it also states “Crotch strap to go through seat and anchor behind chest line. With OEM-type seat, crotch strap may route in front of seat.”
