Suppose it also depends on the structure of the seat. If they're designed to support the belt in an impact then the mounting point behind there matters less. But your average boy racer non-homologated seat won't do that.

I'm just going on what the law says.
Also, the belts look too long. They should be a maximum of 84cm from the centre of the shoulder back
quote:
SVA Manual
. In the case of a fixed (non-sliding) seat, within
840mm. of the seat reference point
• in the case of a sliding seat, within 840mm. of
the seat reference point when the seat is
127mm forward of its rearmost position.
(For seat reference point, see standard SVA
Section 5, Annex 4)
As Ian said, unless the seat is designed to withstand downward force during an impact then it represents a real danger to the person seated there. Regarding WRC cars, the belts are mounted higher and closer to the seat.
I would rather lose by a mile because i built my own car, than win by an inch because someone else built it for me.

Does SVA test thing have any authority on a modification to a mass produced road car?

Technically yes. Any car that has been modified from standard should have a test as the type approval for that vehicle is no longer valid. I have heard rumours that in the near future they will start clamping down on modified cars and making them get tested. I bet 1% would pass at most. FFS I failed as my boot cover projected 6mm when the limit is 5mm from the body. Some of the body kits, engine conversions and and mods I've seen on cars would fail big time at SVA.

belts want to be as straight as possible, as mentioned at shoulder height ideal or the seat will submarine in a crash.
a roll cage is the strongest point to fix the harness, otherwise fixing your whole seatbelt to one anchor point on the rear seats is stupid, hows that thin piece of tin going to hold up in a crash where you can easyly pull 20g and weigh over 1.5tons!

It looks to me like they are mounted to the floor from that pic not the bar?

That's an MOT though. Technically a car should have an SVA if any major mods are carried out like moving seatbelts. The MOT only tests what standards a road legal car should meet. If you deviate from a standard set-up then you really should have it tested under SVA as it no longer meets it's type approval.
Think about this, if you wanted, you could remove the high tensile 8.8 bolts from the standard belts and replace them with mild steel 4.6 rated bolts. The MOT tester doesn't check this but does that make it legal? NO, a VOSA SVA tester checks the tensile strength rating of every bolt and mount on the car.
In summary, an MOT doesn't mean your car is safe or legal.

however it means you can tax and insure it and drive it on the roads.
an mot, well, if the vosa people come to check a garage, the car has to be passable. as soon as its left the mot place, it can be completely unable to pass an mot. but that doesnt matter for another 12 months.
if every modified car had to have an sva test, well, nobosy would own them as i bet 99% would fail and cost too much to make it pass.

Exactly, an MOT is about ensuring a standard type approved car is road worthy, as soon as you deviate from that type approval then the MOT means jack shit.
I think modified cars should have an SVA, the same as kit cars should. It is easy to say that if the kit maker gets the car approved then every one that is built should pass, but that isn't the case. The SVA leans more to making the car safer to pedestrians than just the driver. A kid in his garage sticking a bodykit on a car isn't thinking about the safety of other road users.
