Will I need a driveshaft loop when I go to MATS? I expect to run mid to low 12s and have the M/T Street E/T Drag radials which I think are DOT approved. What to do?

NHRA track with DOTs (aka radials) I don't believe you need a driveshaft loop until 11.49 and quicker.
Still a good idea to have one.
Some tracks have rules that supersede NHRA though, so I would check with host facility also.

I think you need to check the NHRA rule bood to be sure but I was thinking it was way before 11.49. My friends car runs in the 13's and he had to have one. I was thinking it was 13.99

Straight from the rulebook:
"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."
It'll probably be up to the tech on whether or not your DOT drag radials qualify as a slick in this regard. Personally, I would run one...it could get ugly real fast if the front U joint breaks at half track.

Put one on. It's worth it. I broke a front joint at the strip a few years
back. Very glad I had it.

It's silly not to be running one in a car that quick.
They are inexpensive.
