944 calipers on all 4's or Ghia fronts and 914 rears?

Well hopefully dgluyas can help you out.

as for the csp rotors, aren't they the kerscher rotors? on the kerscher site they offer rotors that are 270x20mm in a bunch of bolt patterns including porsche. I know that early stock 944 rotors are 20.5 mm thick when they're brand new, so the thickness is good.

If anyone can find out the diameter of the stock 944 rotors, and if they're close enough in size, you might have part of your problem solved...
