I've sworn off drilled/slotted rotors. Reason?
You warp them, you're toast. Can't turn them, they're trash.
I bought Powerstop rotors from SCA. Cost me $240, warped them in 4 weeks 3k, they're in the dump right now.
Bought BAT rotors, and they lasted 8k miles before they started to shudder. I've got well over 10k on them now, but they need to be turned soon.
BUT, having said all this, believe it or not,
the stock Ford rotors lasted 55k miles!
So, from my experience, Ford OEM rotors are the best.
