rear coilover angles
whats the maximum angle from verticle you can legally have on the rear coilovers before the SVA test fails because of ineffective damping/suspension
setup - i heard it was 40 degrees (acute angle from top to verticle,
anyone any ideas? need to know before i start designing the IRS for the locost 
cheers

i didnt know they could fail you for that. If the angle drops then why not just use stronger springs? there is a thread in running gear ATM about
that. Plus the shockers want to be gas filled i think to use at a large angle, apparently...

I think you could set your dampers to 89 degrees, if the car would be still properly sprung and damper (very unlikely!). The maximum working angle is
set by the design of the damper, not the government
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

....and bearing in mind that your shockers will work best as near vertical as possible as a rule of thumb. Make it a high priority of your design....
Dont just build it.....make it!

it is a high priority of my design hence asking now and not after 
its just that i've been scribbleing down ideas for the IRS system without using s de-dion axle but trailing arm type design

i made my own trailing arm suspension, i wouldnt recommend a direct copy.
reason is I copied parallel arm design like on minis and metros. great as camber never changes with bump. however, there isnt any allowance for body
roll in that type of design.
this is why sierra and most modern cars use a semi trailing arm setup - allows compromise between camber control and body roll

I can supply pics of what i did if it helps
