Man, I’d pull them suckers off & chuck them up on the brake lathe … machine only enough off to ensure they’re true (slots,drill holes,doesn’t matter) and then put a bi-directional finish on them with a coarse piece paper (80’ish grit) and they will be like brand new again…….as long as you haven’t worn them down below specs
Then ask these guy’s on here about a pad that’s ideal for your driving
I currently have the Z1 sprinkler slotted rotors all around & Carbotech XP10’s up front & XP8’s on rear………and to this day….they still look brand new
