Ghia front disc w 944 rears

[bt1211]

Hello, I have 944 brakes front & rear that I want to install. My Ghia has new dropped spindles and I dont want to buy 944T items for the front. Can I use the Ghia fronts with the 944 rears? My car is not a road racer (I'm just a poser). In the future I might switch to Suby power, just not now. My wheels are 16" C2s and I wanted to lose the adpts. I have a set of T1 Porsche drilled rotors. If I stay with theT1 MC do I need a proportion valve? Should I switch to a 944 MC (has 23mm f/19mm r)? If I do that will it have the correct bias? Is anyone else using this set-up?
Thanks
