I need to keep some sort of rear seat in my car for my kids since it will see lots of street action. I would also like the cage to certify for 8.50. Is it acceptable to make the back brace off of the main hoop removable just like the side door bars?
Kind of here nor there as the NHRA rulebook states the bar must be welded in place. "All required rear seat braces must be installed at a minimum angle of 30 degrees from vertical and must be welded in. Page 266, 2009 rule book.
