IVA results

[Big Vern]

Hi Ash,
Does this mean the roll bar is essential and the two rear stays are a requirement? or are the stays required because you have a roll bar?
I couldn't see anything in the IVA manual that said you had to have a roll bar!
It had occurred to me that all that would be required would be a suitable brace across to mount the harnesses from would get the car through the IVA the you could have what ever roll bar you liked after that....
