Well ordered a straight rear hoop. Will have a hoop going spare i think not sure if it will be straight or the one thats leaning inwards. Will upload some pics.

Have also ordered some extra tube as i have a couple of extra ideas.

Dont suppose anyone has any good examples of the side elbow cage bar things?

just found this post.

down the page most of the way the orange one looks great and has a straight front and bent rear hoop. Regardless will have both the hoops by the weekend and can decide!

Let me now which one you end up not using as i may well be interested in having it of you in exchange for a contribution to your beer fund.

cheers tilly

Sure will let you know.

By the way does the cross bar for the rear hoop have to be a set size? I will be bolting my harness to it so just wanted to know if its ok to use a slightly smaller tube.

not as far as i now

i did mine the same size as the hoop just so it looked the same, i have seen others with diferent size cross tubes though

tilly

Does the IVA require any roll bar at all?

No not a requirement

So if the roll bar is not required, is there a requirement regarding tubing size? Seems unlikely.

The roll bar only needs to be substantial if the harnesses are mounted to it, obviously in the iva's view. That's why there needs to be 2 bolts on each backstay and so on.

My car passed IVA with good comments about my rear stays that extend to the rear lower edges of the chassis with 1 bolt in each side

They were m14 though!
