As any engineer knows, protection isn't always prophylactic and how the transmission is utilized (abused or not) can help. Coolers are obviously a plus for extreme use and environments. Not sure what you mean by "granular", but to revisit your question the same thing that damages manual transmissions can kill autoboxes: gear wear, bearing failure and heat.
So the modifications are similar. External coolers, bearing and gear design, etc.
Torque converters aren't just modified for stall speed, but also weight and capacity.

How much of a difference do modern tires make on an old car?
It wouldn't be advisable, no?
Modern tyres one old cars can potentially cause issues around drivetrain components that aren't designed to cope with the additional adhesion provided by new tyres. So you gotta be careful with that. If not being pushed to limits it's not designed to reach though it should be fine.
Life's too short to drive bad cars.
also old performance cars factor the tyrewall compliance in to the suspension design. So new tyres can screw the handling. Michelin made old tyre size for matra bagheera as new low profile were dangerous when pushing hard

I just purchased my first "performance" vehicle with an automatic, a forester xt with the 4eat. On the rx-7 the only problems with the manual transmission are primarily due to drivetrain movement (worn mounts) or instantaneous torque loading (highly modified cars launching at a drag strip).
By granular I mean what are the main things that break, and what can be done to "harden" them.
I'm aware that just about every sporty all wheel drive has drivetrain issues, and I want to mitigate them before I break my new car.
Valve bodies?
I've never heard that this was a problem. With late model cars vs modern cars you can usually pick up a few tenths of a G in steady state cornering. A change of tires can make a great deal of difference in a cars handling behavior.

If you going to do some engine work this article may be of interest to you, if you weren't already aware of the similarities with the STI:

Yeah, I'm looking at some mild work. Keeping the stock injectors and ignition system. vf43, equal length headers, divorced catted downpipe, catback, and new tmic.
Should be good for 300-350 hp/tq and surprising most anything at a light. Trouble is they make that torque so low and have so much grip, I don't want to put my car out of commission.

So here is what I believe to be a 1986 BMW K1200. It's engine is what intrigues me - at first, I thought it may be a flat-8, but I am not inclined to think that is the case anymore.
Is it longitudinally mounted (car speak) and canted at a 90 degree angle?
EDIT: I guess a pic would help.
Sure it's not a K100?

There's a fellachap at work with a new K1300R. I think I like it..

That motor looks like the older cousin of what they are using now in the K1200 RS, which was the same engine they use in Formula BMW cars....its a inline 4 lying on its side...

Well 1200 exists when the Formula BMW car came out (2002 IIRC)....
I am not versed in their bike model lineup though, but it was off this bike:

yes. As said it's a 4 cylinder laid on it's side. Earned the nickname "brick"
