My ST205 has always had a very (very) hard clutch. I have a TRD pressure plate, GReddy flywheel and a standard HD driven plate with thin Kevlar one side and ceramic pucks the other. The ACT pressure plate I had before was the same.
Just noticed on the EPC that the ST205 has and orific block in the clutch line. I remember it well from when I had it out but cannot it's purpose. Any idea what it does? I assume it slows how quickly the clutch can engage when you come off the pedal. As such drilling it larger should have no effect on pedal pressure only the rate the clutch engages/disengages?
