Roll cage with side impact protection
Discussion
Just found this...

Think this looks great. Cant see from the photos but presume the front of the cage does clear the dash. I'm sure the added hassle of getting in and out is outweighed by the extra protection the cage brings.

It's banging your un-helmeted head on it in an otherwise small and harmless accident that led me to abandon this idea after months of googling in the past. for a race car however this is just the job - Unless I'm mistaken, I've seen this car at a hilclimb and it's a very neat installation.
So the 4 cage lower points bolt to the outriggers.
Therefor the strength of the cage relies on the condition of the outriggers.
Even at their best, it doesn't strike me as the safest solution.
I''m not knocking it, there just isn't many substantial points to bolt to!
Similar to my TR Lane bar but with the additional front section!

The two on the raisee section at the back will bolt into the harness points below the rear shelf which are sett into the main chassis rails. It will be the back that takes most of the force as the fronnt has some support from the screenTherefor the strength of the cage relies on the condition of the outriggers.

I would have thought there was no support from the screen, I may be wrong but I'm reasonably sure there is no structural support there.
Yes, my bar bolts at the rear in the same way and also bolts at the seat belt mounting points iirc.
The front add on section must aid support but will only be as strong as the integrity of the outriggers, (mine are on the winter to do list!).

).Those are the chaps who did the cage on my Chim.
To echo some of the points above, a full cage in a Chim/Griff is very dangerous unless you have a helmet. If you take a look at the photo in my profile, it doesn't look too bad, however my cage sits above the standard roofline (ie a standard targa section doesn't fit, and also my seat is about 3in lower than a stock seat.
Secondly the cage in that configuration does rely on the quality of the outriggers, that said if they are shot no sound company on earth would weld on the mounting plates to rotten outriggers - mine were shot but they replaced them for me at the same time as building the cage for a nominal fee (in comparison to the cost of the cage!). It's a bit of a useless point on a road car but with a stripped out dash you can also mount to the two bosses on the transmission tunnel infront of the gearstick, which allows for greater side impact protection (or atleast more lateral support for the A pillar tube), likewise I've got a bar that goes straight across the two B pillar tubes to help transfer the load of a side impact (but does not attach to the chassis).
Finally if you are going down the full cage route, you may also want to add a diagonal in the roof area to strengthen the cage in the event of a rollover to prevent it from lozenging.
