btw, calcs using some assumed numbers for piston sizes show the difference between the 278mm and 300mm rotors on the rear worth about 1.2% on rear bias. Compared to ~1.8% difference for a minor change in friction on the rear.
I'll throw out some actual #'s when I can dig up those piston sizes.

Even with the smaller pads in the rear? Definitely not questioning your expertise, but more or less trying to get an understanding of what you're saying, exactly.

Rear pad size doesn't change. Besides, pad size (within reason) really doesn't have a lot to do with overall brake torque, in fact increasing pad size down toward the center of the rotor (much like how the FSVT pad is larger than the later CSVT pad) will very slightly DECREASE brake torque due to the decrease in effective radius (eff. radius is the distance from the center of the rotor to the radial center of the pad)
Using my assumed piston sizes, my suspicions played out as accurate, but only barely.

Right here, you bunch of weenies. Stay on the shore where you belong.

wow.
Sorry Ryan you where already taken by one of your Marine buddies, 
LMAO ROFL on both these comments. Tears...
My wife came over to find out what was wrong with me.
then she saw the beret on your head

I'm sure theres a squid around somewhere....hiding in the deep ready to pop their head up and chime in.

I calculated about 1% difference, I suppose that isn't much different than what you got, but I wonder why we have different numbers?? 
Either way, I did the calcs and then with actual testing found out I liked it VERY much with FSVT Rotors/pads on the front and with bendix Ti on the rear. Very good feel when braking hard and I even had the bad luck to do real life panic stop on them once where I was limited by the road surface and traction and the ABS kicked in.
Otherwise, with the bigger rubber I had on the car I finally had awesome brakes.

Tom, what piston sizes did you use for front and rear?

 Never mind, I used the CSVT front and Rear sizes with Tod's (TCE) calculators to see what the effect of just rotor sizing would be if the pad compound was constant. Probably too simplified eh?
So it wasn't using FSVT pistons because I was designing it for CSVT calipers all the way around.
