Roll cages

[Output Flange]

I'm looking at a car for sale that's had a custom-designed roll cage fitted about 7 years ago.

Do cages have to be certified as meeting a minimum standard? If so, what's the process for something that's not off-the-shelf?

I'm also assuming that the regs will have changed since it was built, so it could also need modification I assume?

It can be quite complex..

What is the car? Single Seater, Saloon, Sports?
What are you going to use the car for? Speed events (Sprints & Hills) may have different requirements than Race or Rally.
What other modifications have been made to the car
What is the engine size?
Is there a Roll Cage Certificate?

If it is a one-off design, then the cost of getting ROPS (Roll Over Protection System) certified is extremely complex and expensive. I know of one going through a certification process just now and I expect the bill will be well into 4-figures...

Hmmm. So, it's a custom design and I don't know if it has a certificate. Do you have to produce the certificate at every scrutineering session?

If it doesn't have one, what's the process for getting one?

It's a saloon car, incidentally, that I'd like to race in something like the 360MC 6 hour, and other series like that.

if it complies with the msa spec in the blue book, then it doest need a certificate. If however it doesnt doesnt comply then it will need to have a certificate.

This is because the msa spec is belt and braces, a manufacturer will have the capability to optimise the design and prove strength with stress analysis ect and hence will have the cage certified.


chances are if its a one off it will be built to blue book regs so will not have a certificate.

The tuscan cage differs from blue book spec and is msa certified ( i do have a pdf of it somewhere) but I've never been asked for it.
