Anyone know of a roll cage kit that's FIA approved?

In Europe, there are some shops that will sell pefabbed FIA-approved cages. Usually for rallye cars doing WRC. Don'T forget that "FIA-approved" also depends on the class or group in which you race. Don't forget that despite FIA being the world wide governing body, SCCA may have very different rules. There have been ongoing discrepencies between SCCA and FIA rules. Per exemple, for years FIA prohibited diagonals in the main hoop, claiming it could harm a driver, while it was mandatory with SCCA. Does it mean the FIA main hoop is weaker?. Nop. The cage has other reinforcements.

I will be building a rollcage in my M3 this winter. It will be to FIA Rallye specs:
- X in the main hoop
- X in the rearward bars
- X in the roof
- Double V in the doors with gussets (not an X, which is not allowed anymore in BMWCCA CR)
- Double down bars at the A pillar

It will almost be like what I built for my 1969 2002, except for the door bars which will have a 2-piece double V instead of a three-piece X

nice looking cage there. Yeah I've been reading up and it seems SCCA and NASA (probably MCSCC as well) will sign off on a lot of cages that don't meet FIA regulations. Auto Power makes a bolt in cage SCCA and NASA sign off on. What I have noticed is most of the kits cost with shipping is over 1k, and I'm thinking the local race shop in ton could probably build me one for that much. I'm going to go talk to them after the new year.

Lee, out of curiousity, why are X's for the door not allowed anymore? I can't wrap my mind around how a double V would be better.

It's a matter of resistance to breaking during a side impact. It has been the norm for 5 years in WRC where cars often get to meet trees ;-)

A friend of mine built that one

Ahh ok, that wasn't what I was envisioning in my head, makes more sense now.
