Ebay Brake Rotors?

Hey guys. 1st post here(of what will soon be many!)

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? Any suggestion on a better place to buy? Thanks!
Its a 2002 Gsx-R 1k

Things are cheap because they are crap. Brakes are important. You get what you pay for.

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.

Just an FYI I guarantee you those things will warp the first time you really step up the pace and brake hard.

The price is tempting but I don't trust them. Sucks paying 2x the amount but got to remember that an overseas company in China pumping these things out have no liability if things go wrong. Some may say that we have way too many rules and regulations in this country but in cases like this they are meant to keep us safe. Lots of NON-DOT and TUV stuff sold online. Mirrors and things for looks are okay but brakes and other parts that keep you alive worry me.

Yep.
EBC seems to have a pretty kick ass setup with their new buttons that have flat sides to allow for lots of heat expansion to prevent warping.

Biggest issue with most parts made there is they do not do R&D. they simply copy and paste and many times it leads to poor quality.

I can get you OEM or EBC. Bigger discount on OEM.

^^^^ Do This.

The Chinese brake rotor looks like a rotor, is shiny like metal, must be good........ right?

What you're buying when you pay for OEM or respected aftermarket is the knowledge that the company has Quality controls in place. It's the correct material, flatness, fitment specs, etc. If you take all that quality control and overhead away...... you have Chinese prices.

But other than looking like a rotor, you have no idea if it will work. Those Ebay specials could be made out of low grade, high porosity, cast iron for all you know.

May want to hit up some of the racing forums (ccsracing.com , wera , etc...) and see if someone is selling their OEM ones off. Maybe place a want ad looking for them.

I'm not crazy, my mother had me tested.

I would buy the Galfer wave rotors before the EBC. Take a look at those and if you want them I can do them for 15% off and free shipping.
