This is a genuine BMW tension spring, part number 34 21 3 660 186. The number stamped on the part is 34213660186; BMW's catalog files it under the short number 3660186. You will find it on our Brakes shelf, under Rear wheel brake.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on 8 diagrams, among them Drum Brake-Brake Shoes/Brake Carrier (34_0056) and Drum Brake-Brake Shoes/Brake Carrier (34_0057). It weighs about 19 g (under 0.1 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
