In working on my (tube chassis) mk3, I'm playing with ideas on how best to run the cage. I've been searching for photos of mk3s with a cage, and am not really finding much detail on how this is best done. The bodywork is limiting. It's easy to see how to run a front and rear hoop, but it's messy connecting the two hoops, since there's limited headroom already, plus the thinness of the roof between the doors.
Also wondering about favorite ways to connect the diagonals (thru the body) to the rear hoop. Just do a double shear rod end/ clevis? I found this: Lola Heritage News
...but can't really tell what they've done there?
Also, as for building the cage to be compliant for one sanctioning body or another, I'm not that well versed in these regulations. I was just going to use DOM, not Chromoly- I'm only going to do some track days with it, so it won't matter to me, though if I sold it along in 10 years, the new owner may want to go racing, so I'm at least thinking about this.. Any input here is welcome. But my main reason for the cage (Which would just be integrated into the chassis) is for rigidity, not for a certain sanctioning body.
Thanks in advance for any help!
