NHRA rule change for T-top cars in 2004

[Nick Micale]

NHRA has published the following rule change:

"On T-top-design vehicles with an unaltered firewall, floor, and body and running between 10.00 and 10.99, a roll bar is permitted in place of a roll cage."

That's good to hear! That's a big change considering what it was going to be.

What exactly is the difference between a roll bar and a roll cage as the NHRA describes it?
