944T Caliper front vs. Rear

[YllwVeeDub]

I have read through a lot of old posts and am still having trouble figureing out exactly what the difference between 944T front and rear calipers are. They both have a 94mm mounting pattern right? Are the piston diameters different between the two? Any reason not to run 944T rears in the front? I already have my 944T rear setup on the car I'm just trying to sort out my front setup now. Thanks in advance for any help.
