Brake squeal is driving me nuts...

For manual, as long as you know how to match rev there's nearly no clutch wear. Some P-Cars match rev in sport mode automatically.

This. Plus, if I can't do the perfect blip downshifts at each and every stop to show the kids how much practice they need, what's the point?

À propos nothing in particular -- I tend to hear (more feel with my left foot than hear, in truth) a slight squeak when releasing my clutch. Only time to time, and usually at low speeds/revs when downshifting (think crawling in traffic). Do you think it is evidence of an imperfect rev match or just general mechanical craving for some lube (clutch helper spring? something else)? I guess I'll ask the tech at the next service, but if my technique is at fault I can fix it sooner
On my last car (E93) sloppy rev matching usually manifested in a slight shudder but never noises...

Why would it matter whether transmission is in gear if the clutch is in -- with a traditional manual gearbox (which, I was hoping, the 7MT still is) where clutch presumably sits between the flywheel and the box?

Wait... do you mean you double-clutch the 991? Or that you clutch in, switch to neutral, rev match, switch into gear, clutch out?

1. When in gear, clutch in and shift to neutral.
2. Rev quickly while in neutral.
3. Clutch back in, put car into lower gear.

FWIW I tried to rev-match really obsessively the last few days and still feel the squeak sometimes. Gotta mean "lube me"...

So you're clutching out between 1 and 2? To the best of my limited knowledge that's called double-clutching and my hat is off to you -- I have never learned to do the trick properly (i.e. quickly), assuming that with modern synchronized trannies I wouldn't ever need to...

It sounds to me like you have a simple case of a squeaky clutch pedal that needs to be replaced under warranty. My last AMG developed a squeaky gas pedal and they just swapped it for a new one.
