Should I get slotted or drilled rotors?
Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving. This is why high end BMW, Porsche, Corvette, and Mercedes rotors are drilled, not slotted. However, for track racing (high speed stops), slotted rotors are the better choice.

Do you need drilled or slotted brake rotors?
Drilled & slotted brake rotors are also are fine for general use in street vehicles. Drilled & slotted rotors are not recommended for performance racing since the drilling makes them vulnerable to cracking. Why Choose Blank (OEM) Brake Rotors?
Why are BMW rotors drilled instead of slotted?
This gas and dust reduces the friction force by preventing the pad from fully contacting the rotor. Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving. This is why high end BMW, Porsche, Corvette, and Mercedes rotors are drilled, not slotted.
Why do drilled and slotted rotors make noise?
They sometimes create extra noise when stopping. All brakes create a squealing sound when the pads wear down because you have metal-on-metal contact. The issue with drilled and slotted rotors involves the rumbling that you hear because of the slot engagement with the pads as you stop.
What are the pros and cons of slotted rotors?
Slotted rotors already have a shorter lifespan compared to other options for your vehicles. They also cause some brake pads to experience higher levels of wear-and-tear too.
Can you turn slotted rotors?
Yes you can turn slotted or drilled rotors. It’s best to use new bits, and take light cuts. If you see chatter marks after a slot. You either need to change the cutting bits, or take lighter cuts, or both.
Can slotted rotors be resurfaced?
Resurfacing drilled/slotted rotors requires a very strong lathe and you must regear to a slow turning speed and use a brand new bit. Otherwise you don’t get a perfectly smooth surface and weird formations occur in metal when bit hits and skips entering and leaving the drill hole or slot.
Can slotted rotors be machined?
If done properly, and with care, slotted and drilled rotors can be machined. Not all warped, worn or damaged rotors can be brought back from the dead, but more often than not, a proper machining job can breathe new life to your rotors and should be considered a viable alternative to replacement rotors in some cases.
Do drilled rotors do anything?
Drilled rotors do nothing to increase your stopping power under standard conditions. They lighten the rotor slightly and provide better cooling by allowing a better release of heat, so if you have problems with brake fade or warped rotors, they will help with that. But they won’t increase the overall stopping power of the brake,…
