Depending on which pressure plate you are running the air gap from .28" to .55" clearance with the clutch engaged. More or less you can cause damage to the pressure plate fingers or arms. As far as TOB riding on the pressure plate fingers, some do and some don't. IMO I don't like contact of the TOB on the pressure plate. With a hydro system the piston retracts like your brake caliper on your car. Perwear out will happen if the bearing is rubbing on the pressure plate and the fingers or diapham are not all at the same plane all the way around. I have the ERA setup and have run a pull of spring for 15 years with both single and multi disc clutches. Have not worn out a TOB yet. Side note, recommend that you guys run have a pedal travel limiter. This stops over extending. Rick L.
