Centric C-TEK rotors.

I've used the Raybestos "Advanced Technology" rotors on several vehicles and was very happy with them. They're coated, but also advertise lateral runout max of .002. Raybestos also now markets a "Rust Prevention Technology" rotor for a cheaper price. You get the coating, but not the tighter specs.

I've also used the Centric "Premium" rotors, when Raybestos didn't have the AT for an application. They seemed completely serviceable. Personally, I'd avoid the cheaper Centric C-Tek model for something you don't change very often.

While most of the runout is usually from installation issues not the discs, if I got discs with .002" runout by themselves, I'd return them.

In other words, .002" ain't that great, and you can still have much more runout once installed, even if your disc was made to .0001" runout.

I find most hubs to have minimal runout once they are cleaned extremely well. Most of the runout is from the rotor. Usually well-cleaned hubs will have .0005" or less.

As you mentioned, I agree that any rotor with .002" of runout is excessive and is unsuitable for most modern vehicles. For most Asian imports, you really need to have .0015" or less TOTAL with the hub and rotor combined. There is a reason why on-car brake lathes are becoming more and more prevalent at many shops; even new rotors are sometimes unable to meet the specs required.

"Iron is iron". Wow. That is brilliant. So we can be confident that an original uncoated Aisin caliper salvaged from a 1998 Celica in Nevada is made of the same stuff as the Cardone item when one is still rust free after over twenty years and the other has rust growing out of it like moss after one year in upstate New York?

I think I'm going to buy a way to measure my runout before doing my next brake job.
