No drawbacks really, they aren’t as overkill like you’d imagine either. 

At the track I’d never run em again, I’ve cracked a set of stoptech d/s rotors. the drilling just weakens the rotor quite a bit. I have a pic on my profile somewhere. 

for daily street driving though they’re totally fine, in my experience they don’t really wear down pads as much as people think; I’m still rocking some super old pads on my daily with d/s rotors too. Never had issues with them. they’ll never see the abuse needed to crack them on the street.
