I would say at least get aftermarket springs and shocks - do a search on those, there's lots of information.

Front:
Control arms (or replace the ball joints)
M3 control arm bushings
Tie rod assemblies
Upper strut mounts (or camber plates)
Sway bar bushings/links

Rear:
Trailing arm bushings
Subframe bushings
Diff bushing
Rear shock mounts (GC or JT Design)

A good place to source diagrams like that is a BMW parts catalog.

You might as well buy M3 sway bar links and pick up some tabs to be welded in from GC

Rear:
Trailing arm bushings
Subframe bushings
Diff bushing
Rear shock mounts (GC or JT Design)

go urethane on the bushings

Those pictures are from the Bentley Service Manual. If you are looking for more quality pictures such as the ones you have posted I would suggest that you purchase one. They have a fairly large chapter on suspension including pictures of everything. It covers everything you mentioned you are looking for, interior, exterior, engine, electical, etc. I have one and I love it.

If you want stiff, get urethane parts instead of OEM. If you want bone-jarring, get Delrin parts instead of urethane :)

I wouldn't bother with delrin control arm bushings. There was a thread a little while ago that discussed the pros and cons of rubber control arm bushings vs urethane. Urethane will be stiffer but it won't grip the control arm and provide resistance to the twisting force, which is what rubber does. M3 CA bushings should be plenty good enough (I have them and they're pretty nice!).

yes deffinately go with factory offset CA bushings, and i remember hearing that the urethane subframe and trailing arm bushings can cause squeaking. also, whats so 'high performance" about urethane bushings anyway, does it really make a difference when it comes to things like the differential or trailing arms?

Dumb question on M3 CA bushings:

When installed in a non-M car which way is the bushing arrow aligned for better high speed control?

[nando]

well, I'd reccomend urethane for subframe and trailing arms. Mine don't squeak at all. :)

the ca bushings have an arrow on them that lines up with a mark on the mount. the hole goes to the outside of the car.
