I am using a 55bar proportioning valve for the rear. And most of all the stock 3.2l master brake cylinder.
As said, everything is cool but I think I could love a little harder and more defined pedal. Would be using the Turbo master make things better in this direction and is there any ill side effect possible?
Short clip from yesterday having fun at the track..

first you still have a huge amount of front bias, that' safe but makes the front do more work than necessary, it's much better for performance and longevity to take as much of the load off the front as you can get away w//
to that end, ditch the p/v, the stock '87 911 had a 33 bar p./v which was necessary because they had to much rear brake. You have the opposite issue.
the pedal is soft because you went from a pedal ratio of 38.3 to 43.2. You are on the ragged edge of what works. install a 23.8mm m/c from a 930. You will now have a pedal ratio of 32.3. ie what a stock 996 has. Right ~30 is a very nice place top be.
