90q brake conversion & CO adjustment question

[Richard J. Andrews]

Hello all,

I've been super busy and off the list for a while.
Been working steady at getting the old 4kq nice again.
i currently have converted to front 90q struts and came upon some g60 dual 
piston calipers..
I am looking at putting these on my front end along with coupe quattro rotors.
It looks like a direct bolt on... Anything i should watch out for?
also...

does anyone have a procedure on setting the CO mixture i know how to tune 
it with the Diff pressure regulator.
but do i have to clamp off hoses or disable ISV?

Thanks a bunch!
