RECOMMENDED:
SKF, Timkin, Febi-Bilstein, Lobro, Meyle -- Excellent no matter where they're made (unless counterfeit).
NEUTRAL:
KMM, FAG -- Usually very Good, but quality can vary.
I've also had good luck with brake rotors made in China. They're not always pretty, but they're inexpensive and they seem to work (and last) just as well as the rest. When I was in China 2 years ago, the taxis were mostly Mk 2 Jettas with Mk 4 style noses. In fact, more than half of what I saw on the road were VWs or their derivatives. With that many cars on the road, there are bound to be some decent quality parts being produced there.
NOT RECOMMENDED:
DS -- They make CAST front hubs!!! Total garbage, and I think quite dangerous for racing.
VW-Audi -- Many of the CV boots I'd been getting that cracked and failed within a couple of races had this logo. One cracked during installation. Possibly counterfeit, or maybe just on the shelf too long. Not catastrophic, but a real pain in the a&$.
