I came across
Bimmerworld's M3 control arm kit the other day and had them confirm it's mostly from Malaysia (and then the usual:
For the E9X M3 control arm upgrade kit, all of the arms are from the OEM manufacturer TRW.
The Front Left Wishbone and both tension struts are made in Malaysia and the Front right wishbone is made in Germany.
These are all OEM parts so they are built to the same specifications as the original factory parts and BMW replacement parts even carrying the same warranty, I'd have no concerns about the quality of the product.
The more I see vendors I either have good experience with or hear good things about not having any concerns with the TRW not-from-Germany parts, the more I'm inclined to just get them and not worry. Or maybe I'm just getting impatient (hey, it's spring and the roads beckon – but first, track day, then RSFBs. Focus!).
