Cool pics @MightyMouseTech I always enjoy reading your posts. I use to work at a VW Subbie store... its weird how the Japanese always want to "turn" the rotors while the German's just replace them. I think it also has to do with the type of steel(used) in the rotors. I think the German's use a higher quality of steel. Maybe thats why our rotors get surface rust so fast.
Btw... another reason why brake rotors warp or the brake pedal pulsates is due to the rotor not sitting flush on the hub. Most guys don't take the time to use a 3M "cookie" to clean off old rust on the hubs before mounting new rotors. Not doing so can make your pricey new rotors feel like worn out ones in no time.
