I've raced a variety of vehicles on the Bonneville Salt Flats for 30 year, where safety regulations are extremely... well... ... extreme! Hence, I quickly became a fan of locating an excellent car builder with adequate experience with roll-cage construction and have always been pleased in all regards going that route. Construction MUST be done with the correct materials and construction procedures, AND fabbed to each individual vehicle. I would never, ever buy "off the shelf" roll-equipment, period... well, unless it's purely "show" for bench-racing sessions and/or coffee klatches. You give no indication of what your "need" actually is, but if it is really racing of any kind, remember it is always potentially life-saving equipment, and I assure you that having been on the outside of such situations looking in (on a couple rare occasions), you do not wish to be on the inside with a wonky cage. All the best; stay safe; have fun!!!
I have built many roll cages for SCCA road racing.
If you are actually going to race the car, you need to read the rule book carefully for your racing organization to find the minimum tubing diameter and wall thickness.
The SCCA rule book actually describes tubing size, wall, and how the roll cage is constructed.
An SCCA approved roll cage (inspected, stamped, log book) will probably be acceptable for IMSA, NASA or other racing organizations.
As stated above, Bonneville and Open Road races have their own cage spec, usually much thicker wall tubing.
The last cage I built was in a C5 and it was a tight fit. C8 is going to be extra tight.
Connect to the rear shock towers is required in SCCA. That rear glass is going to have to go, and Lexan put in it's place in so you can cut holes for your rear bars.
Keep us posted, this is interesting. You can see the C5 interior was stripped. If you intend to keep your interior panels intact then it will be an extra extra tight fit.
