Salut!
Hum.... Je vais ecrire en anglais, c'est trop tard dans la nuit pour ecrire en francais ;-)
Here in Germany we had a lot of different BX-Accessoires. Well, Rémy is almost right already, as always
The correct name for the Swift alloy wheels is "Swift2", I dont know if there ever existed a "Swift1", in fact i have never seen them yet. The Swift wheels were standard on the limited models BX "Chamonix" and BX "Fit". You also could buy them for the AX models.
Spirit F2 was standard on the BX "Le Mans", that was the last limited edition for the BX in Germany, sold in late 1993 until early 1994, basis was the BX 16TGI.
The car on the left in the above picture is an XM, thats why there are 5 trous ;-) The wheels are called "Exip", but you also could buy them for the BX, with 4 trous
Musketier was a famous german Citroen tuner. They made lots for the BX, but also AX, ZX, XM. I have some brochures, when I will have some more time, I will post them here.
Another one is called "Postert". Originally that is a great Citroen dealer in Germany. I also have some brochures from them. One of them two sold a special front bumper, I dont know who it was. But it was put right over the original front bumper, without taking it off before.
Another german accessoires producer was "Pfeba". They made spoilers (bequets?!) for the back of the BX. There were two, one below and one over the rear window. They also made them for the break models. By the way, the "spoilers" below the doors on the red BX above, those are from "Pfeba".
