Headrests and IVA
It's just occurred to me that I might be lining myself up for an IVA fail. I am using the MX5 donor seats in my car, this type;
But I'm wondering about the fixed head restraint element. Are there specific rules that I need to adhere to, which would make these seats fail?
They're pretty solid restraints, but they're not adjustable.
After checking the IVA I can see the only check is the height needs to be 700mm from point R, which itself is 54mm off the seat base. So do I just
need to make sure the top of the seat is at least 754mm from the seat?
As a follow up question, if it's not quite 754mm (EG 20-30mm out), would removing some of the seat foam be enough to satisfy the IVA?

"Tombstones" are designed to be used with a diagonal 3 point seat belt.
For 4, 5 , or 6 pointers you need MX5 seats with the restraints on stalks so the belts run over your shoulders.
I have both types of belt/harness in my MiXi but I also have both types of seat so I can swop for the track if need be.
I have also "foamectomy'd" my seats, but without sitting in them they measure the same.

Yes I'll be using the 3 point seat belts so that should be ok, and thanks for the foamectomy info. Makes sense that it doesn't change the
measurement unless you sit in it.

An electric carving knife is the tool to use.
