Chinese car parts are a joke. I bought brake rotors that were Made in China and the first hard stop the warped. I mean the very first hard stop.
From my experience, that’s completely true of so much stuff made in the PRC. It seems everything they produce, from poisonous dog food to absolute garbage lamp parts, is a deliberate consumer ripoff unless it’s made on contract for a large, powerful foreign company that has the contacts and power rigorously to subervise its PRC contractor(s). Compared to Mexico, where the language isn’t that hard to learn, the country is close, and there’s some cultural commonality, that’s ahard barrier to surmount.
