What parts to keep off a parts car?

[theosinc930]

Hi, my E85 Z4 from 2003 with the 2.5 M54 engine was rear ended in September. I'm buying a parts car to use the body panels and fix mine. The thing is that I want to keep some expensive parts from the parts car that could fail on mine and then get rid of that parts car, because I don't really have the space to store it. What parts should I keep? I've thought of the following:
ABS/DSC pump
Electric steering rack
Soft top+ pump
Differential (mine has a bit of play)
Any other expensive parts that might fail?

airbag modules - be interested in the left bpillar one if you dont need it and part number is a match

65776948087 65776928571 65776928520 65776926784 65776926782

headlights, some of the front bumper undertrays etc are expensive too

I’ll take second refusal on the airbag modules please if numbers align and previous poster doesn’t want

What parts should I keep

I guess it depends on how much storage space you have I sometimes see people buying new steering wheels when the material on the old deteriorates so you could remove that? A spare set of wheels can always be handy to keep winter tyres on or just in case of unrepairable puncture.

Yaw sensor, GM5 module, roof control module, door lock actuators, window regulators, handbrake assembly if the teeth are good, Steering Angle Sensor, Light Control Module.
I would buy yourself a few stacking boxes with lids that you can find room to store, then fit as many parts in to them as you can.
I always keep as many of the trim clips etc as I can as well.

If you remove the airbag modules, try to keep as long a section of the electrical loom with each one as well. On occasion the plugs corrode and they are so fiddly that it is easier to splice in a new loom.
