I bought some rotors off of ebay and they were pretty cheap, they warped after a few months, then I found LUK Schaffer Brake rotors on sports brake rotors and I have couldn’t be happier. I got a set of BLACK XD Brakes and installed them on my Mitsubishi Lancer and they're simply amazing.

I have Cross Drilled/Slotted installed on my Mitsubishi Lancer Yes I know that not how they are from OEM but I don't do any AutoX. They look sweet and stop nice. I think I've had em for about 20k and no warping whatsoever, just smooth braking.
