Better braking courses of action from least expensive to most expensive: So, drilled holes make rotors worse, in my personal experience. If they are simply cross drilled or slotted they will not help with heat dissipation.

That’s where slotted and drilled rotors come in. Drilled rotors are for weight reduction and looks. Drilled rotors are much more prone to failure under heavy use, however.

Furthermore, the holes drilled provide a better cooling effect from the heat being produced by heavy braking; Mike skelly of wilwood offered us a little history on the origin of drilled rotors. On the other hand, the slot helps in sweeping away gas as well as dust, which comes from braking.

Modern brake pad material really negate the need for drilled/slotted rotors. If weight is the issue i have to say ok, i have nothing to base an opinion on. The purpose of both is not so much cooling but gas relief, which with what we are doing isnt a problem.

They were about the same price as my powerstops and the quality is much better. Drilled rotors develop cracks which start at the holes and spread out like spider webs, leading to early rotor failure due to cracking. I think the difference is that they're more robust.

Better braking in muddy conditions. Also warping rotors is pretty uncommon these days. Drilled rotors’ holes, combined with the vents, let dust and hot gases escape more easily, carthrottle explains.

If you’re thinking about a disc replacement today, then here are the pros and cons of drilled and slotted rotors to think about. If you do regular and frequent track days, a slotted rotor may yield slight benefits. Most likely you have inconsistent pad deposits on your rotors, not warping the actual rotor.

Blank rotors are going to be the strongest mechanically and have the most thermal mass, which is why they're used in pretty much every motorsport application. They crack easily at the drill points under heavy use so they aren't used on track. There's a lot more bite now.

Also, slotted drilled rotors do not provide better cooling than the same rotor without slots and holes. Drilled and slotted rotors don't offer a gain like people think.
