Re: Say No To Bolt-In Cages!
This is why you don't skimp of safety... I've always loathed bolt-in rollcages, especially in C5s that have aluminum/balsa wood core floor pans. Hey but they pass drag racing tech so who cares right!

Re: Say No To Bolt-In Cages!
Lets say I own a shop that builds full custom roll cages and someone comes in saying they want one but not to waste money on reinforcing the floor. What would you tell them? I'd tell them to get the fuck out. And I'm not sure how neither the driver or passenger, lol giving rides in a car like that, didn't get hurt. Kinda weird lol

That scenario is about the worst that could happen... a 4000lb poopstang doing a front flip right onto the roof. That said a properly engineered rollbar should be able to take it. Most bolt-in and kit "rollbars" are marketed as chassis-stiffening bars to do product liability.
A proper setup will integrate into the frame and have a diagonal bar for more strength.

Here is the problem with a bolt in cage/bar. The corners of the bottom plate. They act like an old timey can opener. Think of it like this, once a soda can has a hole in it you can tear it in half pretty easily. If the mounting plate had it corners rounded and a few welds it probably would have turned out better.

Re: Say No To Bolt-In Cages!
Correct me if I'm wrong, but wouldn't the exact same thing happen if that was welded in? No matter if it's welded or bolted, if it's in the middle of just a floor panel and not over the frame rail it's still going to punch through. But that obviously wouldn't be a properly designed rollbar if welded like that. I'll have to check to see where my Autopower 4pt mounts.

The can opener analogy is awesome though, I love stuff like that.. It really is a perfect way of thinking about what happens in some situations.
