Drilled and slotted rotors are a gimmick. If they actually cooled quicker and faded less, then why don't race cars use them? Less metal for heat dissipation, greater chance of cracking, and accelerated pad wear.
Mine with the Z36 powerstops looked identical. Two of my caliper slide pins were stuck. Only got about 40k km on em.
New Z36 pads and had the rotors turned.
Those rotors would have been fine to have turned.
Slotted and drilled rotors aren't necessarily made to last longer. They're made to cool quicker with less fade.
