Pad area shouldn't really change bias. The surface force is less per sq unit but it's acting over a larger area. The larger pad helps it to wear less because temperatures are lower per area. It also smooths out any catching making it easier to progress to the limit of slip.
I run 0.625" front master and 0.7" rear master. I'm also running a slightly higher diameter of 11.44" on the rear which increases the bias a little too. I had it around the wrong way at the start of the thread but the Wilwood will further increase the rear bias not reduce it (larger area at the same PSI = larger force).
I have a spare 0.625" master which I'll install to bring it back towards center again. (or maybe I switch masters front / rear).

Iīm gonna mount Superlites 11.75" at front and Powerlites (1.58 sq piston area) 11" at rear (i canīt find two piece rotors instead sport ones).
I have right now dual master cylinder setup with .625" bore front and .7" bore rear, rear proportion valve and remote brake bias for fine tune.
I think i will buy HP+ pads for front and rear but itīs very difficult for me to try to compensate everything before mount it. I have no knowledge to calculate all variables.
