JustinOlson Posted January 4, 2008 Share Posted January 4, 2008 I'm getting ready to build a 10pt NHRA cage in my 280z. I have a few rust issues that I have to take care of in the floor pan. Does cutting the rust out and replacing it with new sheetmetal count as a modification to the factory floor pan? If it does, it looks like I need to add a rocker bar to the cage on both sides. Thanks for the help.. Regards, Justin Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted January 4, 2008 Author Share Posted January 4, 2008 Here is part of the rules that has me worried: "Unless an OEM framerail is located below and outside of driver’s legs, a rocker or sill bar, minimum 1 5/8-inch x .083 CM or .118 MS or 2-inch x 2-inch x .058-inch CM or MS rectangular, is mandatory in any car with a modified floor or rocker box within the roll-cage uprights (excluding 6 square feet of transmission maintenance opening). Rocker bar must be installed below and outside of driver’s legs and must tie into the main hoop, the forward hoop, frame, frame extension, or side diagonal. Rocker bar may not tie into swing-out side bar support. If rocker bar ties into side diagonal more than 5 inches (edge to edge) from forward roll-cage support or main hoop, a 1 5/8-inch x .083 CM or .118 MS brace/gusset is mandatory between the diagonal and forward roll-cage support or main hoop."

johnc Posted January 4, 2008 Share Posted January 4, 2008 Rust repair does not count as a modification with NHRA or SCCA as long as the repair is an OEM type repair. Quote Link to comment Share on other sites More sharing options...

Well, I would be using new sheetmetal, but not really changing the design of things. I guess I'm safe then. I'll be using the bad dog rails, ect.
