When you get to where it is required for your situation (9.99, 135MPH) then it needs a tag.


Thanks guys! What if the car is say, a high 10 sec car, but the cage is required because the floor has been modified, or maybe the firewall has been modified? Would the cage need a tag then?

Also, what does the NHRA consider a "modified floor?" If subframe connectors are installed through the stock floor w/ 2x2 outriggers to the rockers (also through the floor) for the main hoop to land on, does that mean the floor is now modified, thus requiring a cage w/ sill bars?


Frame ties do not constitute a modified floor, Typically you are allowed a 6 square foot area of removable transmission tunnel before anyone says anything.

Convertibles also need a full cage at 10.99.


Thanks for the clarification. I was worried that my subframe connectors and outriggers would require me to install rocker bars since they protrude into the otherwise factory stock floor. Unfortunately, the rulebook allows for multiple interpretations. Thanks again.
