Surely is better than springs, but the problem with G27 pedals are 2:I have replaced the spring on my G27 brake for these soft rubber pads, that are kinda foamy material.
(that was handed to our workplace, to put under computer case legs, when they did bedrock explosions next to the building, to kill the vibrations that came from the blasts).
It's not load cell, but with very aggressive curve on the pedal input (ingame), i can now brake with muscle memory, (rather than foot position memory).
It's propably nothing even close to a real load cell, but already made a huge difference.
And made me faster no doubt.
1 is the 256bit resolution of the pedals, the other is that potentiometers are not consistent enough. In the years I've customized the pedals, for starter with a usb cable (Leo bodnar) that should up the data resolution to 1024 bits, then with a load cell and a signal converter for it.
The pedals are quite a easy base to customize.
