The top harness mounts look like they may present too sharp an edge, maybe the bolt caps, and/or the bracket itself.
I personally don't like the high extensions either, but they do line up with the seat holes which is a plus. Structurally though, they are weak
and will easily deform in an accident situation to the detriment of the wearer.

weld a support bar within the roll hoop for support?

Yea, I was going to put caps on the bolts. The extensions may well fall off after the SVA.
I was trying to line up the harness with the seat holes

I passed with a similar system based just upon some tube slightly bigger than the M8 bolt!!

Are the hoops mountings strong enough? I would either weld them or at least use 4 bolts per mounting plate. If you weld a support bar, the hoops will
be non-removable anyway, so better to weld them onto your car.
Do you have a strenthening construction underneith the horizontal member?

I'm going to stick my neck out and say I don't think those mounts will pass the SVA.
The tester is looking for mounts that will take a force of 3 tonnes and comply with the manual - tubes welded end-on will not.
I had great difficulty persuading the third tester to pass mine (see photo). On the basis of his comments, you will need to weld fillets to support
the sides of your tubes where they stick up from the cross-member.

PS Given that the effective height on your car is determined by the harness slots in the seats, could you not sink the threaded tubes into the
cross-member, which would then satisfy the diagrams in the manual.

If you are going to SVA in Southampton 'fraid the mounts and belt plates will not get past Mark's eagle eye.
I zipped tied seat belt buckle covers on top of the mounting plates which he passed.
As far as the vertical tubes as has already been said^^^ I reckon you need to put fillets above and below the tubing to stop it being ripped out under
crash conditions.
HTH. Cheers, Pewe 
Reckon PaulBuz's below looks ideal

Its all fairly simple really.
Ask just one question......
Would this be strong enough to save my life (or my passenger) / would I let my life (or my passenger) depend upon this?
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.
Best Regards

ive seen a few go off-road so to speak and they held fine - all depends on the quality of the chassis provider and the weld.
moral - if in doubt, strengthen

... but how do you know if it is strong enough without testing to breaking point?
how do you know the bolt or belt will not fail?

Just for clarity....
The bolts go all the way through the tubes and bolt onto the cross member

Its hard to tell from the pic. but Iassume that hey bolt onto a new box section on your chassis.
I would be worried that when it mattered, due to the long leverage of the bolt/thin support pillar, that it may rip through the box section.
As someone has already said.
If in any doubt..strenghten

I fixed my mounting points by welding in a cross tube to the roll bar, at the right height
