I am about to replace my stock rotors with Brembo rotors, does anyone have any experience with the slotted or drilled Brembos? I like the looks of the cross drilled better but I'm ignorant about the diff. with one over the other. Any feed back or opinions welcome.I searched the threads sorry if I missed it.
Thanks,
Scott

 

Slotted. Drilled rotors look cool, but actually can make the rotor more prone to warping and cracking. A rotor is a heat sink, removing material via drilling reduces the amount of available heat sink. If you are NOT going to be doing any heavy tracking, or if you are not a heavy "braker", more than likely you would not have problems with the drilled. If it were me, however, I would definitely get the slotted rotors (if that).

 

Think of slotted rotors being knives slicing very thin layers off your brake pad. True, slotted does give you a "fresh" pad and stops you faster and less fade than drilled but man, you are gonna change pads very often. Between drilled and slotted, I would go drilled because the dust and gas can vent through the rotor and heat can dissipate better

 

Slotted all the way. I have slotted brembo rotors. They bite like crazy. If you aren't going to track your car, then you can go with drilled. I wouldn't exactly call it slicing. It's more like scraping. But if you ask any slotted rotor owner, they won't complain one bit about changing pads more often. It's pretty much insignificant.

 

Dumb question....What is considered often from mileage standpoint? I just replaced my stock pads and i have only 12K on the car. Is that what you mean by often?

 

I have yet to see technical data to back up your last statement. How is decreasing the overall surface area better for heat dissipation? The only benefit I see from drilled rotors is for less unsprung weight.

 

so i have read a ton of posts about the rotors issue (i am about to get the brembo slotted from tirerack) but one thing i've heard... are they LOUDER?? because not on this forum... but people with different cars have made that point... though i get the feeling they dont know what they're talking about.

but is it true? do slotted rotors end up somehow sounding louder than solid disc rotors??

 

Define louder. Is the typical brake noise louder? Or do they mean squealing from the brakes? Brembo slotted rotors are nice, but they are one-piece and heavier than stock. If I was to do it again, I would have tried to find a place that offers a warranty on two-piece slotted rotors like racingbrake.com.

 

 

I always go w/both...so slotted/xdrilled

 

Why?

 

Neither for street and occasional track. Cross-drilled for bling.
