stage III clutch and thrust bearings

[KMinAF]

What kind of problems if any might I encounter running an ACTstage III clutch in regards to premature thrust bearing wear? The pedal is noticably firmer than the stock unit. I have already disconnected the clutch switch so the engine is always started without the clutch pedal being pressed, when coming to a stop I usually just push it in to neutral and I never wait at a stop light with my foot on the clutch.

This year I will be going to the local track and the thought of high RPMS with my foot on the clutch makes me a little nervous or am I just being overly paranoid?

The next to the last thing I want to do this summer is replace a crankshaft due to worn thrust bearings.

I think the thrust bearing wear issue is really there at start up.

I pre-lube my engine, so even pushing in the clutch, the thrust bearings are being oiled as the entire crank is floated on better than 30psi of oil film.

My thrust bearings are also molydisulfied coated, so they retain oil, and the moly makes them slide better if there is metal to metal contact as well.

One thing to keep in mind when building a 7M, is that along with the journals, the thrust bearing surface should be polished too. (Most machine shops hand them back with a very light cross hatch/machine turned surface.. this could wipe oil off the bearings, and cause acclerated wear, sort of like teeth on a saw cuts through metal.)
