Brake Disc sizing and balancing

Brake Disc sizing and balancing
I’m hoping for some help with a brake setup, I am in the process of upgrading the braking system on my RX4 while retaining the stock diff and 4x110 PCD.
I am using S4 FC discs up front, with new steel hubs and Wilwood callipers. The reason for the wilwoods is not so much performance, more so that I can use my wheels and the FC discs combined.
For the rear of the car, I was thinking to use S2 RX7 discs (GSL) as these will retain the 4x110 PCD. I have some GSL rebuilt callipers and all the brackets/cables etc and I am hoping these will work without to many modifications.
What I am not too sure about is the balancing of the brakes, what is the best way to do this, use the stock GSL proportioning valve?
And is there a ‘rule’ as to the difference of size between front and rear disc size?

Looking at the whole setup, I think the best way forward will be to just use an aftermarket proportioning valve, the Wilwwod units are around $80 so not such a large investment and like you said, I can set the car up how I like.
There is a size difference between the FC and GSL disc size, hopefully this will not be an issue.
