| Re: roll cage pictures please
Having built a number of cages / cars certified by the SCCA, I think the only one cage that I've seen on this site to date that would pass the stringent certification process is that of Ron's.. Ian's RF117 is very close and from what I can tell only one tube short of being a contender. I've not seen all of Ross' cage so no comment.
Despite the obvious lack of side impact protection (which is required for all wheel to wheel competition cars) - there's also the lack of shoulder height lateral support bars on many of these cars as well as lateral support bars at or just below the dashboard. These lateral support bars *must* be made of the same alloy, dimensional material as the main hoop and the A-Pillar support tubes. All tubing must be DOM tubing with absolutely no ERW tubing. Not certain why the requirement for DOM as no one on the SCCA Comp Board not myself have ever seen ERW fail as a result of the way it was made (welded).
Randy - For most "track day" use, your car would not "require" any cage. However - you've recognized the obvious need for self preservation and want to construct something that would likely do the job in the event of an incident.
I like the execution of the cage in the cockpit area of Dean Lampe's car and think that it is sufficient for track day use. I like the idea of the removeable upper bars over the door opening to keep the front and rear hoops in check.
I have some other concerns on some of the cages I've seen here but they are mine alone at this point so I will reserve comment. |
