Senco Rotors?
#3
I don't know if they're the same as Porsche OEM, but if they are, that would be a good reason to avoid them. Have you noticed how quickly the Porsche rotor hats discolor, chip and rust? There are several posts here on repainting the Porsche rotor hats, which would not be necessary if they weren't so poorly finished. I would get Zimmerman or Ate coated rotor instead.
