I plan to take this on for myself. Alright here's my question(s) what size pipe/tubing should be used when making a roll cage? I was considering 1.5" tubing. Mind you its only going to bea 6 point cage. Connecting at the rear shock towers, front up by the "Dead" pedal and lastly behind the seats. I've made measurements of hte main hoop being 114.5" long, the main hoop-to-shock towers being somewhere around 28", the main hoop to "dead" pedals being 58" and finally the cross bar being 52 7/8". This is for a CRX. If someone could give me measurements of an existing roll cage for my 90 CRX, just as a reference I would greatly appreciate it.
