Hello-
I noticed you guys mentioned the 944 brakes could be had a realitively low cost. What is the price differential over some ghia brakes? If I could do some Porsche brakes for not too much more, why not? 
I spent $250 at the junkyard for all the parts plus a pair of 944 trailing arms. Let's say $180 here for brakes.
Then, I bought caliper rebuild kits (~$30 total), carbon-kevlar pads (~$150), new cross-drilled vented rotors (~$300), an M14x1.50 thread reamer for the studs ($2), new front bearings (~$30), a new 944 MC (~$100), some epoxy paint (~$30), and some 944 e-brake cable ends (~$20)
So, that's ~$850 for the whole mess with 100% new "important" parts. A Ghia front is $350, a rear CB is $250, and a new MC is $50, so that's $650 for the whole mess new for that configuration.
The difference is then about $200 plus machining.
IMHO, the simple 944 system isn't necessarily superfluous. AFAIK, somewhere around 0% of new cars are made without vented front discs. Even a Geo with rear drums has front vented discs. JMHO... nothing more.
Take care,
