clutch upgrade kit for Fanatec CSL pedals

Simple and easy to print upgrade for Fanatec CSL clutch pedal.

It is possible to print from PLA or PETG. PLA is strong enough, I am using my PLA prototype for one year.

List of needed hardware is in attached PDF.

How does it work?
The added spring creates a higher resistance when the pedal is depressed, the more the pedal is depressed, the less the resistance of added spring applied, until the resistance disappears completely at the end of the stroke.

A high resistance at the beginning and a smaller one at the end simulates the behavior of plate spring in real car clutch.

Shifting using the clutch is then much more natural and there is less frequent "tooth counting" and mishifts due to an incompletely pressed clutch.
