P-31 option, is it really worth the extra money?

Nope, p31 replaced it.
A lot of Auto reviewers, including dedicated enthusiasts, wrote that the p30 was too stiff and MB responded by eliminating it. Oddly, and reportedly by mistake, early USA 2009s with P30 had the LSD and brakes of the p30 but not the suspension. And p31 replaced p30 in nov 2009 so there are some 2010s with p30.

AFAIK, the 30+ hp is coming from software changes not the forged internals. So get a tune and you can make 40-50hp+ and the speed delimiter instead and save a ton of money or get LSD.

Had the P30 and agree that it is indeed a little on the stiff side for daily use. It would have made for a great sport setting on an adjustable supsension.
What does the Mbrace cost and how does it affect the ride/handling?

96 and 08 911 turbos
Forged pistons are typically heavier than the standard hypereutectic pistons, which will likely be balanced out by the Ti rods. However, that will be basically a wash, and I doubt you'll see significant power gains here.
The forged internals are by far overkill in a little 11:1 compression motor. unless you want to run this thing on the ragged edge NA (and even then you can melt a forged piston) or run spray/boost, forged internals will just be parking lot bragging rights.
as for the rest of the stuff, thats up to you.
