went to the track and failed tech!

As long as you don't have any cord showing, or belts slipped, they should pass. Now, I wouldn't run one that way if it was really low on tread. Roll bars are now supposed to be in anything 11.49 and quicker, or 13.99 or quicker in convertibles.
Long studs on DR's? I can understand if the car is fast enough. At that point, they would also have to have after market axles.
 
Whats tech?

I just drop it off the trailer, sign the waiver card, drop it at the tower, and race.

Sometimes they make ATV racers wear long sleeves, though!

That's test and tune night.

I got sent back for running my ac in the staging lanes one time, and dripping condensate on the ground! Different track.

At a new track, you gotta ask around before you go to tech! I have all the stuff that I know I need for NHRA Sportsman racing, based on a 12 sec and slower ET, so I can race at FFW's.

But it takes some asking, etc to get it all the way some want it.
