If you were racing a V8 super car then possibly you may require as much if not more piping. But considering as has been said above we are dealing with a relatively low powered car you are just dragging the chain. Besides this, the driver (no offence intended) probably won't be able to tell between an extreme cage and a basic six point. To clarify a couple of things too, make sure you do not penetrate any of the cabin. In other words you can not make the roll cage (In club racing) go through the fire wall to the struts nor through the rear wall to the struts. However as this car does not have a rear wall as such, it is possible to tie the rear struts into the cage. They cannot however be used as the structual base of the rear legs. CAMS describe a roll cage as a "safety cage" not a structually integral part of the car. Unless of course you are planning on making a specific tube chassis which then falls under a different section of rules. A few things to look out for is the foot print of the mounting point. It needs to 12000mm2 as a minimum and a min thickness of 3mm. The mounting footprint can be bent around say a inner sill panel but the top faces minimum width/length must not be thinner than the thickness of the cage. All bends must have centerline bend radius that is atleast three times it's diameter. Anything tighter and it weakens the structure of the bend. The bends must not be heated to bend. There are special bending machines available that provide the specific bend and radius required. All bends must have a minimal crush and the difference between the nominal dia and the thinnest part of the bend must be 0.9 or greater. Also wall thickness and diameter have to be considered. All pipes except the main hoop require 38mm dia with a 2.5mm wall or a 40mm dia with a 2mm wall. The main hoop requires a 44.45mm dia pipe with a 2.5mm wall thickness or a 50mm dia with 2mm wall. Intrusion bars must be level with the top of the drivers hips. and must provide adequate room for entry and exit. There are soo many other aspects of the cage that have specific guidelines but I won't go through any more as they are pretty straight forward common sence stuff. But things liek visability etc must be abided by. As for triangulating everything well you are totally correct. Triangles are a cages (and for that manner anything structual building bridges etc) friend, however you have to weigh up the pros and cons of what is being done. The best cages aren't ones with pipes going everywhere, it's the ones that provide adequate strength with minimal weight. Hope that helps, Tark [Report message to a moderator]
