Rusty Old Z Posted September 5, 2018 Share Posted September 5, 2018 Was going to use DOM 1.50 x .120, does anyone have blueprints on measurements, or a rough idea of how much of how much steel I am going to need to do this? Car is a 72 240z. Quote Link to comment Share on other sites More sharing options...
calZ Posted September 5, 2018 Share Posted September 5, 2018 That depends on what you want to do. A single hoop with two backstays? Include an X? Land on the floor or strut towers? The answers will vary quite a bit depending on what you're aiming for. Quote Link to comment Share on other sites More sharing options...

Ironhead Posted October 15, 2018 Share Posted October 15, 2018 (edited) If you are bending it yourself, I think anyone who has done it will tell you, calculations are kind of meaningless because you are virtually guaranteed to have to scrap a lot of tubing because of do-overs. Maybe not so much if you are just doing a simple hoop, but definitely so for a complete cage. If someone out there can nail the complex, multi-plane bends in one try, they are a better person than me.... I would say for a simple hoop you "might" get it in one try...depending on how perfectly you want it to fit. For a main hoop you will need a single piece about 13' long. But a single hoop is of no value without back braces and cross braces, and what you will need there depends on your design.

JMortensen Posted October 16, 2018 Share Posted October 16, 2018 The guy who did mine used that pic and calculated it out. He also owns a race shop that builds a whole lot of cages. Another way to do it is to bend conduit to shape and then bend the tube to match the conduit. That's how I did the halo and A pillar bars in my cage.

That's how I did the halo and A pillar bars in my cage. That definitely would have been a cheaper approach. I probably wasted at least 20-30 feet of tubing with screw-ups bending mine.

fusion Posted December 4, 2019 Share Posted December 4, 2019 Does anyone have pictures of the fitment of this hoop in their Z? Close ups would be really nice. Any reason the fitment would be any different in a 1976 280z? Thanks much in advance. Quote Link to comment Share on other sites More sharing options...
74_5.0L_Z Posted December 8, 2019 Share Posted December 8, 2019 (edited) My posts in the thread above show the fitment. Edited December 8, 2019 by 74_5.0L_Z Quote Link to comment Share on other sites More sharing options...
