I've heard a couple guys on the binary group say that everywhere their frames cracked was at a weld. Also in industry, they engineer parts to shed(come apart) in a particular order. I would rather have the bar break the bolts than bend the frame. Even if it caused some body damage. Body repair and bolt replacement ary easier than fixing the frame and they will go back closer to original form. Maybe even grade 5 or 2 bolts??????? My 2.5 cents.
