WA R36 parts: coilovers, BBK, exhaust OR modified R36 wagon

[Spaceman]

As title says, I'm looking for some key components that would fit an R36 wagon:

KW V3 coil overs
After market exhaust system
Big brake kit

OR

A modified, clean example wagon with some of the above mods.

Thought I'd give it a shot if anyone had these parts/car and wanting to sell.
