Back when I was into DSMs, dragging clutches often caused similar issues, but usually the cause was insufficient extension of the clutch slave. From the feel of where the engagement point is on mine, it seems like I'm overextending it if anything.

The trick on DSMs to check for this was to turn off launch control, start the car on a level surface, clutch in, shift into first, and rev to ~ redline. If the car creeps forward ever so slightly, the clutch is dragging.

I may turn off the launch limit (or just make it = to redline) and try this quickly to rule it out, but usually the clutch drag is caused by not pushing the slave far enough to full disengage the link between the gearbox and the flywheel.

Thanks for the suggestion!
