I’ve been reading through the rule books and I’ve searched the forums but can’t seem to find any info on this.
Are sheet metal gussets that attach the roll cage to the factory A or B pillars legal? Are they considered attachment points? If you don’t know what I mean do a google image search for “roll cage gusset”. I’m not talking about the “taco” or triangular style connections between roll cage tubes, I’m referring to sheet metal panels stitch welded between the roll cage and the chassis. I’m bringing my car to my welder to help install a new seat and was going to have some minor cage updates done at the same time.
