One of my front brake rotors is warped pretty bad and I'm looking to replace both. I'm a little weary of these Chinese rotors off ebay, but they are a great price! Any thoughts on the quality of these?
Did you mean "weary," or "wary"? Not trying to nitpick you, but it makes a difference in this context.
It's fair to be wary of them because the price is so low. But, they're Chinese made, so they're going to cost less to make, so they're going to be cheaper. I don't see anything obviously wrong in the listing, although it strikes me that these particular rotors may be going for looks rather than performance. It's not possible to see from the listing how well the blades are riveted to the carriers, which is kind of a critical detail. On that basis, and the lack of return privileges, I'd be cautious. Other than that, the listing seems to say all the right words, so they should be OK for standard duty if you're willing to keep a close eye on them for a while to make sure they're not disintegrating.
One word of warning: with this being (evidently) a no-name outfit manufacturing them, you don't have a good way of knowing whether these are good or not. On the one hand, they could be factory seconds from one of the big names in the business, and excellent quality but for a couple of surface blemishes. On the other, it could be some dude in a shed with a CNC machine, buying parts online and then, in effect, Xeroxing them, carving them out of whatever material is handy, with neither any idea of how to do good quality assurance nor any intention of wasting time doing it. You really won't know until you've got your hands on a set, and it's a gamble until then.
On the other hand, if you really are weary of the ones you already bought, why are you asking? Ditch the junk and go get a decent set of rotors from a reputable parts dealer. My EBCs have done all right for about a year now and they weren't nearly as expensive as the OEM ones. There are certainly better brands than that out there for more money.
