Question:

I have a 1995 Mustang GT that I think will run in the mid 12 second range.  If I run DOT street tires will I need a drive shaft loop?

 Answer:

  In the 2019 NHRA Rulebook section 4A page 4 of E. T. DRIVELINE it reads “Driveshaft loop required on all cars running 13.99 (*8.59) or quicker and utilizing slicks, except vehicles running 11.49 (*7.35) seconds or slower equipped with street tires.”
