For now its a daily driver, but I do intend to slowly build it out to be a drift car. I've heard that drilled rotors can form micro-cracks around the holes and need to be replaced every so often. What yall think?

Slotted and drilled: https://www.rockauto.com/en/moreinfo.php?pk=11610153&cc=1431309&pt=1896&jsn=3866

Back in my pre-college days I got slotted and dimpled rotors. I heard about the cracking and dimples, not drilled completely through, resisted cracking.

I had regrets ever since. Forgo drilled/dimpled and stick with slots. It turns out dimples create tiny air raid sirens as they sweep past the pads and I heard the reflections off sound walls and adjacent cars. Drilled doesn't do that much anyway from what I've heard.

No complaints with slots though. Had those on 3 of my cars over the years.
