The other question I have is and sorry if you have answered this previously, What master cylinder are you running?
Tilton twin masters with bias bar and no booster. For sure the effect would be lessened with a larger master on the front but I'd need to spend more time at the gym to be able to press the pedal.
There's a couple of things I will try now including removing the spacers and loading the bearings, and sticking a camera under the guard to get a better look, stuff I can try between track days.
The pedal at the moment isn't terrible just that it could be and used to be better.
