What's the difference between slotted and drilled rotors?
 

What are the main differences between installing drilled rotors or slotted rotors? I've seen some rotors for sale that are both drilled and slotted, but I've also heard that with any performance rotors like these that cracking can occur much more often than in stock rotors. Is this a real issue with them, or did I just about someone's bad experience with poorly manufactured ones?

The '02 ES comes stock with slotted rotors up front, so I'd say there's nothing negative about those as long as they're from a quality manufacturer.

I remember a lot of debate over cross-drilled rotors a few years back, but haven't since followed up on it. Makes sense, though, if you're drilling holes through the rotor, you're going to weaken it.

Are the perferred method for sheding rain, even before you need the brakes, especially here in the great Pacific NW.

??? Are you sure? I've yet to see them slotted. Or any lexus rotor. Maybe you mean vented.

Just asking :D

:eek: You're right. :o Ventilated it is. My bad. I thought slotted = ventilated (the rotors look like they have slots in them, haha) = I have no idea what I'm talking about.

PS Any reason the rear rotors weren't ventilated as well?

My personal opinion:

The rear brakes are only used for about 20% of the stopping power. For a car, they don't get that hot. Therefor they don't need to be vented. But an LX470 on the other hand, has vented rear rotors due to it's extreme weight (6800lbs).

Thanks for the explanation. :) Makes sense.
