### Roll Cage Setup
Posted: Fri Jan 04, 2013 11:08 am
Hello!
I am working on car to hopefully be ready for SCCA Vintage racing and I would love to do some HillClimbs.
Specifically Giants since it is near my old home-town.
The car is a 1967 Pontiac GTO. It should be running and driving in about 3-4 months and painted and "neat-and-clean" hopefully for June. I'd like to run it at Watkins along with my SRF when they do the vintage HRG racing there.
Anyway, I want to make sure the roll-cage setup is correct. I am finalizing a design for a cage now I think I have understood the GCR correctly, but I'd like to verify
This link shows a drawing of basically what I am thinking.

Some specific questions based on the GCR are
1) full hoop behind the driver and passenger to the roof of the car (2-inch
margin to helmet/etc). Correct?
2) Horizontal brace bar behind the passenger/driver seat for seat bracing and
belt attachment
Question: does this need a lateral support bar here? Running diagonally?
3) Two rear facing support bars from the full hoop to the trunk area
4) Full loop around the roof to the windshield with a "cross brace diagonal"
5) Support bars coming down in front of the windshield/dashboard to the floor.
6) Horizontal brace bar between the front support bars in item 5.
Question: where is a good place to locate such a bar?
7) On the doors. A "x" style brace across both passenger and driver door. Possibly with two plates to "taco" the X together?
Some of the drawings show two forward bars going from the support bars in
item #5 to either the firewall and/or through the firewall to the front frame.
Is this required?
My plan would be to run the GTO is the HRG3/HRG5 group or if I am feeling silly at least to have it classed in SPO
I look forward to any suggestions and/or pictures of roll cage setups
