Quick update

On the T-LCM's put in the strongest springs along with just washers, now the pedal hardly moves ;-) No more spongy brake pedal... Run the Tuning tool and put 3.5% of deadzone which basically removes about 30% of the pedal travel, set the brake force to 30% and now I can modulate the brake much more consistently.

In GT Sport you have to remember to "warm the brakes" or it auto calibrates on your first application and it is very odd for the first few braking attempts...
Did a quick warm up at Laguna Seca in the ND and got a decent time, best of all it was much easier to get consistent times.
