However I am not sure what is avaliable from any of the specialist to fit either and to be IVA compliant ?

thats rubbish.
simple physics here the action of the proportional valve will be relative to the inertia/mass of the vehicle. the iva man asked me why i didnt fit the ford valve to my car so its quite apparent that its not an issue to use them.
if it were me knowing what i know now i would be fitting the valve to avoid the roller test. much simpler to drive the car round the iva station and slam the brakes on and see if it locks up at the back first than it is for them to mathematically calculate it on the rollers over 4 points. you can also test it at home easily by driving down the road and slamming the brakes on while a mate watches
