If you are fitting the 190 calipers to the front, are you going to fit the 190 master cylinder and the larger servo that goes with it??

I understand that not doing so can make an imbalance between rear and front brakes that can cause the back end to be a little unpredictable on wet corners...

The larger pot volume in the front means a bigger master cylinder stroke is needed to have the same piston deflection.. if the master cylinder is not fitted, it could mean more brake force to the rear than is needed and not enough pressure to the front.. I learned that lesson early after fitting the setup to the front of a ZT I had... no such issue after fitting the correct master cylinder...

The push rod to the servo is a different bore as well so the bigger servo is needed.
