Slotted Rotors howl

I have a set of slottled rotors on all four corners, with only 15,000 miles they howl,vibrate quite a bit. Not a wrapped rotor type of vibe, but it's still harsher that I would expect.

But, I am childish and like the looks.

Is there a fix? Can I have slotted rotors turned (I doubt it). What about drilled rotors? Should I grow up and get normal rotors lol?

not sure what your problem(s) could be but i know for sure that slotted and drilled rotors cannot be turned.

driving is poetry in motion.
