Discussions I have had here with other members about roll cage thicknesses indicate to me that 48 or 50 mm diameter with 2.5mm wall thickness is the minimum, made from CDS2. However you would need to check with RAC MSA for full and final confirmation. Getting a fully complying cage in its entirety is really difficult in a 40 replica (or original) as there is not a lot of height above your head! In Greece apparently they only require the engine bay struts on a GTD racing out there.
GTA, correct me if I am wrong here please!
So if you ever come to UK to race, you now know what you need!

Eric,
Further to Malcolms knowledgable reply to you, do you mean racing outside the U.S.A?
The British RAC MSA Blue Book clearly states what is required and i,m sure your US regulations are similar.
Whatever you do though do plan it and fit it early on in your build as to do it retro spectively will lead to many problems!!!

Eric,
As you are from Canada, you may be racing in both the US and Canada. In this regard, I would suggest contacting the sanctioning bodies directly, and talking (not just writing) with the technical teams about what you are doing, what is eligible, and what they will accept from not only a roll cage standpoint, but also from a fuel cell perspective. Remember, a rool cage is not just something to keep your head off the pavement, but also to prevent chassis collapse or crush on certain impacts. Each sanctioning body may have some specific opinions on bracing, door bars, etc. Without talking to them directly, you take a huge chance in building something you cannot race anywhere but an open track event. Another question is will the sanctioning body allow the car you are building. Some vintage organizations in the States will not permit a replica. So, research your project to be safe...
