Word. They are way overrated.

Brembo Blanks &gt; Cross-drilled and/or slotted rotors.

are u sure the Si aren't the same size as the Integra's because when I need new disc's in the front they had no more for my car. So my mechanic got me integra ones. He told me they were the same size. Did the canadian Si get the same size brakes as the integra?

Wow, first we had the "drilled/slotted rotors own regular rotors!!!" bandwagon. now we have the "drilled/slotted rotors are weaksauce cuz they break!" bandwagon. I'm not taking a stance either way.

...but to be completely fair, stock honda calipers probably cant use either type of rotor to their full extent.

Yeah, I have to agree.

I remember when some of my friends saw 'em or read about 'em, whatever. They all thought they were gonna switch to drilled/slotted rotors and save TONS of money on rotors, b/c they were gonna last forever, etc. etc.

Now if you take away the part that they all drive like maniacs so it wouldn't have made a difference anyway, the moral of the story is that they burned through quicker than regular blanks.

As for me? Luckily I didn't have a lot of $$ at the time to run right out 'n buy 'em so I kept the 4 wheel disc blanks on my camaro O.O Poorness FTW!!!

i had the brembo cross drilled/slotted on my hatch (ls brakes). i finally had to change out the fronts last month after 4 years on them as they warped. mine never cracked and i run the canyon home every night. i dont know if they helped b/c i did the whole LS suspension/brakes conversion, stainless lines and aem pads all at once so who knows if they did anything??? i only got them b/c i got for the same price as stock at the time (a friend got em cheap for me). im not saying they are worth it, but i will say the "cracking" accusations are a bit harsh. i could see a v6 accord or a maxima or something cracking b/c of excessive hard braking with them but my car is a dx with ls brakes so maybe it's b/c the brakes are better than the car. but even with the canyon driving they were good for 4 years. oh, they were brembo all around but as i said i just changed the fronts to "88rotors" rotors. feels the same but without the shaking steering wheel when i brake. on another note, the aem pads were okay, but just okay. i got the autozone $20 pads after the fact and it brakes a little better now. the aems last a friggin long time but they dont stop so well... dont know if that makes sense but it's true... anyway, my cd/sl rotors never cracked. dont believe all you hear. someones friends cousins unlcles sister who knew someone who knew someone had ones that cracked, but maybe they are just on crack??? anyway, i still have the old rotors in the garage if you want pics to see that im not full of it. they look old so i doubt you'll question that ive had em for like forever...

rotors that are cast as drilled or slotted are ok, and will usually not crack. But the majority of drilled AND slotted rotors that you see on ebay and stuff, are usually brembo blanks that have been drilled and slotted, meaning the stucture has been compromised, and they can crack, not often, but more likely to.

FYI, Brembo does not make drilled AND slotted rotors, just one or the other.

Slotted rotors are pointless with the kind of pads we have now. Slotted rotors were supposed to keep your pads from glazing over, but that is not a problem anymore. Now slotted rotors are just cheese graters for your pads. They shed water better, but that really is a mute point.

Drilled rotors are supposed to stay cooler and not overheat. The front rotors on cars now are vented to start with, and that is usually enough to keep them cool. That, and blanks have more surface area to dissapate the heat, thus keep them cooler. Guess what most people that road race use? BLANKS, not even brembo most of the time, usually the cheap Autozone blanks and the likes.

And finally, more surface area for the pad to contact equals better braking. Thus, drilled and/or slotted rotors are a waste.

I've been roadracing for 22 years. If you GAVE me drilled rotors, I'd throw them into my scrap metal pile. People seem to always say the holes cool the rotor. Think about it. The way rotors are cooled is air enters near the hub, goes through the center vent area and out the outer circumference. If you drill holes, the air has a place to escape, rather than cooling the outside of the rotor. You want that? I didn't think so. Carry on, now.

my experience with slotted/drilled rotors wasn't a good one. Bought the brembo slotted/drilled rotors from 88 rotors with PBR pads. The difference was noticable compared to stock but i'm not too sure if it was the upgrade of pads or rotors? My girl even noticed my car braked better and she's always been in the passenger seat. After 4 months the rotors basically were warped, i had 3 of the my buddies who know there **** check the rotors and they said there fine but really they weren't. They performed like they were warped, still dont know what the problem was. So I read and researched (what i shouuld of done) brembo doesn't make slotted/drilled rotors only one or the other. With the outcome i threw the rotors/pads away and resurfaced my oem rotors...paired them with hawk hps pads, works great.
