I thought all the Haldex AWD stuff was made in Sweden, Hungary (and Mexico)? There are lots of things I would buy Chinese-copies of. Body panels, exhaust components and other such things. There are only one or two factories that make carbon Golf bonnets, for example, so whether you pay £300 on AliExpress or £3000 from ECS, it'll be the same item. A safety critical, mechanical item, with no background, such as a differential though... The only such item I've seen with any success are the BONOSS bolts @travs uses. They're actually a pretty nice item, with rolled threads and (some) proof of being TUV tested.
