Magny Cours GP "gentle" track lap inside Ford Focus ST mk4 2.3L Ecoboost 280ps with the following (exhaustive) list of changes:
- Mountune panel air filter in standard air box
- Pumaspeed Tracklite wheels with Toyo R888R tires 235/40R18
- Puma Schmiede torque arm mount

I stop the session due to clutch slipping. Looking for a diagnostic to understand if the problem comes from the clutch itself or the clutch command fluid.
