That's all well and good if you're making a strictly race-only car, but frankly he wouldn't daily drive that car anywhere with that much modification. And how much weight do you think all that tube steel is adding? We're not talking about OMFGBBQ uber racecar roll cages here, just a little added protection in a rollover. BTW according to Autopower, their Race Roll Bar meets SCCA organization rules for "most" vehicles (see Appendix C of the SCCA rulebook).
