Anyone have any ideas if the rear parcel shelf isofix point would be strong enough to attach the shoulder straps to? (STi8) ... or should I look elsewhere?

James, I was hoping the loop built into the bodyshell would be ok without going the whole hog and putting a roll cage in there.
The rear straps should really go horizontal from the back of the seat shouldnt they? to prevent the back of the seat from being pulled down in the event of a smack.
I'll have to take the rear seats out, and parcel shelf, to see if there are any 'high up' fixing points.

Horizontal is best...
You *could* drill through the metal-work & mount hooks as long as you had a good backing plate. Better to not have them vertical (as might rip sheet metal) but facing in the direction of load, so as to spread the force.
I don't know enough about isofix points.
The roll-cagey thing is there for info/advisory. There was a passenger last year that broke their neck @ Donno when the car rolled & they were strapped in with a harness.

You can't use the Isofix mounts. Apart from the fact they are stressed for children, not adults, the mounts are a different thread to 7/16 UNF harness bolt mounts.
The Sabelt 4 point harnesses I put in my MY02 STi were mounted to the standard seat belt (and fitted in addition to them) mounts under the back seat. You have to use longer eye bolts (which are not easy to obtain) and be VERY careful with the centre ones and shim them out with washers as they can bottom out as the hole is blind, and I believe it is the petrol tank behind.
Also, you really shouldn't fit them with standard seats unless the belts are LOWER than your shoulders where they go through the slots in the top of your seat.
It isn't an easy job to fit them, and should ONLY be done if you are competent - or you could end up, in a serious accident, going through the windscreen with the belts flapping in the wind behind you........

The point is that if your body is held in place by a harness, then there is less movement (of the body) available in case of accident, therefore any impact will concentrate it's force on the point of least resistance - your neck/spine
With a normal belt, you are potentially able to have lateral and some vertical movement which means that movement acts as a shock absorber to the impact, so less likely to severe injury...
