For most performance applications slotted is the preferred choice.
For many years most racing rotors were drilled. There were two reasons - the holes gave the "fireband" boundary layer of gasses and particulate matter someplace to go and the edges of the holes gave the pad a better "bite".

Improvements in friction materials have pretty much made the drilled rotor a thing of the past in racing. Most racing rotors currently feature a series of tangential slots or channels that serve the same purpose without the attendant disadvantages.

So yes, for a tracked car you will see better braking performance with a drilled or slotted rotor. Car makers (Ferrari,Porsche etc..)do not just haphazardly put drilled and/or slotted rotors on their performance cars just for looks!

Thanks for for the correction on the dual piston.:thumbup:

 

Hows this setup?

Brembo Blanks... with AEM High Performance Brake Pads.

 

dependable and not much different than stock. slightly better stopping power, but not alot. a little more dust.

blackhorse:

hmm, i disagree about the slot/drilled advantages, being that the slots or holes provide less surface area for the pad to use to create friction and stop the car. also slots and x-drilling tend to eat pads much faster than a regular rotor which can eat into your wallet too at any rate, i track cheap autozone rotors, well because they're cheap and do the job.

 

My front pads need to be replaced soon and my rotors turned (Honda OEM). I'd like to switch to a pad that will make a little less brake dust and a rotor that well, won't rust.
Any suggestions for that?

i agree i hate that the inside hub part of the rotor rusts on most hondas
the way around that is to buy rotors that are treated with the gold colored zinc coating. ive seen some on ebay and around the web, i know brembo also has some treated ones too, although i dont know if they market rotors with and without the coating. i do know that rotors ive bought from brembo to date have not come coated with zinc, even if they were pictured as such.

the friction surface is obviously going to rust because the pads are constantly working over that area.
[edit] type= clarification
meaning the pad contact area will rust if the brakes have not been used recently. example: as in rust spots will appear overnight after it rains.
[/edit]
but the rest of the rotor shouldnt rust for a while if its been treated

BOth the Prelude and CRX have Brembo Plain/Blank rotors, stock calipers and AEM/Nissin pads. The slotted and or cross-drilled rotors are no better on a track car in my experience.
BTW: Brembo is a manufacturer of the blanks used to create slotted/drilled rotors. They also machine them for sale in their kits.
If you need more stopping power, then consider upgrading the pads with any of the better brands such as Hawk, Performance Friction, and even the AEM/Nissin (they are better than stock). Also take a look at the rest of the package including tires. This suggestion is for a daily driver/track day car.
Happy holidays

 

Cross/Slotted = Track only
Blanks = Daily driver

I like the look of the cross drilled... will my pads wear out fast. I know slotted do because the bite on them are sharp enough to cut your hand. But im willing to get the Brembo X drilled, i like the look and would be nice to have. Thanks!

 

slotting may (though i believe they don't) improve cooling and long term performance, BUT imho they aren't worth the pad consumption. they don't really help. on a TRACK (roadracing track) prelude i would use the cheapest rotors i could find, which come from autozone or kragen. for OEM replacement rotors on a daily driver, i'd use brembo blanks.

 

Any recommendation on pads that don't say produce as much dust? Just sayin because I'm tired of cleaning my wheels so often. =)
