I think you maybe within the 45deg angle from horizontal, which is doable. However, due to the length of the shoulder straps they should really be crossed over at anything beyond 500mm from the seat back to the mounting point. High angles also really require a suitably rated seat due to the increased loads.
Take a look through the Tillett instructions for some guidance, Page 21 onwards.

Ideally, someone needs to come up with a proper harness bar for the K11. Most people state no more than 20deg from horizontal, (some 10deg), but that's pretty hard to do in anything other than a bespoke installation. Basically the closer the harness angle is to vertical, the greater the load is onto the shoulders and spine, which can cause some pretty severe loads to the occupants in a collision. Not including the lack of and impracticality of HANS of course
Not intending to have a go like, just to keep peeps safe. Being in a process of recovering from a spinal injury, (not related to motorsport), I can tell you it's not a nice journey to make and any preventative measures that can be taken get the thumbs up

Read the documentation that was provided, its all in there. Good read, especially when it can save your life and most importantly the passengers.
Yes correct. It looks to be more than 45 deg. As Low rider says in an accident this would force your shoulders downwards.

I remember seeing the mounting angles for the waist harness as well. Where are your andy?
May be worth looking into making / sourcing an aftermarket harness bar

WTF.... no one told me these exist! WANNNTTTtMay be worth looking into making / sourcing an aftermarket harness bar

blomin eck! anyone would think im doing a touring car micra haha
i dont have a 5million point harness just a 4 point one.
what ive read is the ones that go over my shoulders should go over a bar which is near to me at no more than 20degree angle to the entry hole to my shoulders and then can be bolted down to the floor however it wants.
suppose i best take it to a motorsport garage and ask them what i need to do.
the way ive got it your all saying it will kill me? goodness! that means the normal seatbelts would utterly destroy me if i rolled it over in normal seats lol

No, not at all. More that, in the event of a head on crash, you are more likely to be in an unfavorable situation with that setup.
A roll over scenario is something completely different. Yes multipoint harnesses will offer additional driver protection, i.e. keeping you in your seat, but the fact that you do not have a rollcage fitted could render that point moot.

Just precautions tbh mate, do as you wish. 4 point is good, use what you got, just set it up to the best you can.

no way to escape the roof when it suddenly drops 12 inches.
Mine is a Janspeed 9-point bolt in cage, (13-point as Safety Devices would put it). The harness bar isn't where I want it though, so it will require some additional bars welding in pretty much where they are on the above cage. The bottom bar runs across the top of the wheel arches, so is within the 45deg window but still outside the 10-20deg limits that most harness manufacturers seem to refer to.

Is that I give up and drive a Micra or Eh up I'm from Yorkshire http://www.autocar.co.uk/car-news/new-cars/electric-volkswagen-e-revealed
Around 825kg i think mate
The manual covers from 93 to 02 so it covers both pre and facelift but doesn't specify individual weights for specific years/models/specs
Pretty sure your power to weight will be 'acceptable'
No worries.......as I said 'acceptable'
