The roll cage was built in the summer of 2013 by Mike Modena, of Modena Motorsports in Scottsdale, AZ. This was done before the new chassis was found to be so deficient, but was only tacked in place to allow for later disassembly. Also, the bars extending into the trunk were not done due to time constraints.This is lucky, since those would have had to be redone due to later chassis mods. This took about 5 days, but it is just like I wanted it.
I combined cage requirements from multiple sanctioning bodies, to ensure I could pass tech at lots of different kinds of events. My past hobby was drag racing, and it was interesting to me that the NHRA had the most lenient requirements.
Main elements are made from .120 wall, 1 3/4" diameter DOM mild steel.
It is all my brand new tubing bender wanted. Bending required more force than I would have guessed.
I am blessed to have a shop with full HVAC, and room to do this.
It was a workout for Mike too.
Got to make some sparks!
One diagonal brace is required on the main hoop by most groups. Mike made a jig to keep it aligned as it passed through the seat belt bar.
I had just bought a new dual disk clutch and aluminum flywheel, so Mike is mocking them up for me.
Diagonal bar must terminate at the intersection on main hoop and roof bar.
As you expect, the min hoop anchors to the frame, and not the floor pan.
The bottom bar that is just above the door sill will protect from guard rails trying to enter from the side.
Bar at A pillar had to go through dash to keep it tucked tight.
