I'm thinking that since there is 6% difference between the two on the front and back that the 15/16 is going to take longer to stop the car. You are going to have more travel on the brake pedal than you will have on the 1 1/32.
This all might be wrong of course. LOL!

If you are going to use skinny tires up front it is most of the time beneficial to move more braking power to the back to keep from skidding the fronts. The smaller bore cylinder will take less effort but more pedal travel to achieve the same line pressure as the larger bore cylinder.
