Cage Install

[JayG]

[QUOTE=thstone;586640]I'd suggest that you really want the FIA bars (the two vertical bars that support the windshield).

That's interesting as our cars have high strength boron steel in the A pillars to keep the windshield from collapsing.

Not saying you can't be too safe however and from the pics, it looks like the boron steel is not enough.

I know from an acrobatic experience at the track that the windshield is very strong at least in a slow single roll over. In this case, no cage, just a brey krause roll bar extension. We walked away without any injury to us.

High strength boron is strong but brittle (just like the factory stainless roll bar). So probably great for a slow roll over but when it fails it won’t bend like a mild steel cage it’ll tear. This is why cages have to be carbon steel

That makes perfect sense

Here's one with multiple rolls, still held up pretty decent, I guess these were slower speed rolls, it says they left the track at 65?

I think there is another video out there showing this from the following car but naturally I can't find it now.
