474K? Damn! I may be catching up...424K as of Friday!For the burb, I've kept it oem. I was thinking of one day trying slotted rotors . However oem has worked fine for 474kmiles

The primary purpose of MOST drilled/slotted rotors is to provide enhanced profits to the importers and retailers.That's what I'm figuring, but I imagine they have a use, otherwise they wouldn't exist - right?
Drilled and slotted rotors are big in racing for several reason. Primarily dissipation of heat and weight reduction.
I am not a fan of drilled rotors, they have a tendency to crack between the holes. Slotted rotors are fine if you can find any that aren't also drilled.
So in summery plain old stock rotors are great for our trucks.
A rotor with a surface interruption (slots, & etc.) help evacuate the outgassing from the brake pads when they get hot.
That used to be a big issue but no more. Modern pads don't outgas much at all.
They can sometimes run a bit cooler reducing warping slightly due to their increased surface area, and in the case of holes air can be pulled through the holes dropping the temperature further. This is a small effect at best.
IMO on a race car that's turning multiple laps on a road course at speed, sure, the extra cooling from a slotted rotor might help things live longer.

Not original miles but the braking system has been stock setup. Only modified components are ss brake hoses.474K? Damn! I may be catching up...424K as of Friday!
If you already have them, run them. Just check for cracks whenever you have a wheel off. When you replace pads, do a thorough inspection.I wish I'd read this thread sooner. Living in the mountains and hauling firewood to heat the house, I bought into the hype. Parts are still in the barn waiting for the snow to be done and it's to late to send em back.
