I'll tell you that INSTALLING the Calmini cage is...exciting.
I had mine done by a very skilled welder, and it took us 12 hours. Hope you don't mind FLAMES! We had a few "oops" moments, as things caught fire.
It's some really TIGHT welding.
And now, because I have a really long body, my head is always bumping into the roll-cage padding.
I got the padding from Summit Racing, I think.
