Break bias with NA 944 rears

[super71beetle]

Hi guys, I wanted to get some opinion of the brake bias i might be in for with my setup - I have a 71 super beetle with ghia disks up front, and i just got some early NA 944 disks for the rear. It has a stock master cylinder - should this be a good setup? Theres a lot of people doing crazy brake conversions on here, hopefully someone can help a brake conversion newbie!
