Off the Xmas card list
There is a forward angle of visbility requirement . This is set up an apparatus that is essentially a wooden pantograph with spirit levels / angle finders included plus a length of string ! I can't remember off and but think all the details are include in the section ' forward vision' section . The apparatus ( think his name is George by the way ) sits on a block of predertimied size that sits on your seat . The piece of string goes forward at an angle and above that line must be no obstructions.This is not meant to be a "how to" but it will hopefully dispel a few myths about the BIVA test.
It will be a slow to update thread as I have no proper idea as yet as to what I will need to do to get a pass certificate - it's pretty daunting just reading the manual and trying to understand the paperwork involved - but that part will be looked at later (once Ive understood it).
Some of my mods will be a bit odd, but that's because I'm altering a finished car - if I was doing it before it was painted & finished it would be much easier to make everything correct and still look 'cool'
I'll start at the beginning as that's a very good place to start........
This is what has to pass the test.
I'll start at the front and concentrate on the car up to the windscreen for tonight.
The scoop will need to go as it will fail on 'restricted vision' (otherwise it would pass as all edges meet the correct radii - it unbolts so no issues there, though I may have to make a low scoop to cover the hole in the bonnet). The rest of the front is ok I think as it meets all the radius requirements.
Anyone who has passed the BIVA test, please let me know if I'm right or wrong on anything listed tonight or in future posts.
This means you CAN have scoops and blowers fitted providing the radii is correct and they are not in the line of vision. Note this is the laid down line of vision which may not agree with your true line of vision.
the height of this can often be varied to suit an existing car by raising or lowering the seat but you must watch how it affects the shoulder belt mount on the seat belt IF using lap and diagonals( see what I mean about one thing affecting another?).
