Pagid oranges used to score the rotors on my Targa like that. Hawk HT-10s didn't. That scoring is not because the rotors are drilled -- it happens on 'plain' rotors and slotted rotors as well.

Not sure why they even put brake pad sensors in cars.

I like slotted rotors to get a visual idea of wear. I hate drilled rotors. I don't know why Porsche insists on using them. I think there used to be a reason but I can't remember what it was.

Drilled/Slotted mostly for the visual.

Drilled/Slotted mostly for the visual. Brakes are there to convert energy from momentum and dissipate that energy in heat, cooling required and rotors are basically heat dumps, so without the holes and slots
more metal to work as a heat dissipater.

The holes were there to vent gasses that were produced when the pad heats up. The gasses made the pad into an air hockey puck and torque went way down. Modern pad materials don’t off gas’s like the old materials did. Some systems forced large volumes of air over a d through the rotors. The holes increased the air contact surface area. Mass only helps to a point. Lots of mass only means a longer time before the rotor is saturated. The right combination of mass and heat removal is key.

Thank you all for the opinions. So, I'm just going to put new rotors and pads on it and tell my lovely wife to drive faster.
