Brembo Cross Drilled and Slotted Rotors

[tr0nic]

Okay guys, time to get those brakes up to par for the trip to fest.

Full set of Front and Rear Brembo Rotors with Brake Pads

Cross drilled/slotted brake rotors are known to enhance the braking power of any brake system without doing any major modification. The added air surface , created by cross drilling will increase the rotors ability to dissipate heat and cool down the whole brake system more effectively. These rotors are stronger, truly balanced and will not crack.

BS. Cross drilled rotors DO NOT:

enhance braking
last longer
resist cracking under harsh conditions.

[tr0nic]

I'd love for you to provide some evidence to back up that statement.

[Ferrari-Nick]

Its not really the heat reduction. the pads have more to do with the fade. the sloted or drilled surface alows the gasses trapped between the pad and rotor surface to escape resulting in more friction and better stoping. it dose help. but the cracking is up for grabs.;)

[Auto-X Fil]

Pads have not outgassed severely enough for holes to matter for decades. All that holes/slots are going to do on a street car is make the pads wear faster and look bling. Under street use, cracking is pretty negligible with quality rotors. On the track they're seriously unsafe.

I'm going to be running my Contour at Watkins Glen on August 21-22. Come up and see what people are running. I guarantee you there will be nearly all blanks. I'm talking about very heavily modified cars with massive multi-piston Wilwood calipers. Track-only beasts with the best brakes possible, to scrub off 130-140 mph speeds coming into the bus-stop. They run good pads and ducts to help with temperatures, because holes do nothing. They run blank rotors because they are stronger than drilled rotors, and stop every bit as well.

[Rara]

Hmm, maybe I'll throw my educated $0.02 in here . . .

Cross drilled/slotted brake rotors are known to enhance the braking power of any brake system without doing any major modification.


Known by who? No one that has any engineering knowledge or test data of an actual brake system.

Brake power is determined by 3 things, friction level between the rotor and pad, pressure/force applied from the brake caliper to the pad, and the effective radius of the brake rotor. Slots and Holes do nothing to affect the peak performance of any of these factors.

The added air surface , created by cross drilling will increase the rotors ability to dissipate heat and cool down the whole brake system more effectively.

You are almost correct here, but the point is irrelevant, because the potential minor increase in airflow doesn't affect the system until AFTER the stop is done. The rate at which heat dissapates from the rotor is extremely slow compared to the rate at which it is "dumped in", and the only thing that helps as the heat is being absorbed by the rotor is the mass of the rotor, which is decreased by drilling holes in it. You will also note that I said POTENTIAL minor increase in airflow. Unless the rotor has been designed from the outset to have holes drilled in it, and the internal vane structure is designed to use those holes effectively, the holes will actually make the airflow WORSE as they don't allow the vane structure to work as it is designed to in pumping the air from the inside of the rotor to the outside.

These rotors are stronger, truly balanced and will not crack.

Since you first asked for "evidence" to Phil, I'll ask you right back, what data do you have to back up these claims? What wonder material are you using to make them stronger than the typical gray cast iron rotor? What balance specifications are these rotors held to after the drilling and slotting? What magical fairy dust are you using to stop crack propogation?

See, now I'm giving you crap, not because these rotors are bad, but because you are making ridiculous marketing claims that not even a brembo engineer would make. For starters, these rotors are no stronger than any other brembo rotor, in fact, they are probably not as strong as some of brembo's other rotors, because these are outsourced to someone else to make, because brembo only casts thier OEM products in house. Anyway, I digress, the point being, while these rotors are plenty strong, they aren't any stronger than any other quality rotor (assuming you haven't drilled those silly holes in them). In regards to balancing, brembo usually does a pretty good job at that, but they usually only do cross-drilling and slotting in house on very high end products and only for cosmetic reasons (think Porsche and Ferrari). Now, the part here that really pisses me off, is the claim that they will not crack. Utter and complete BS. All rotors will eventually crack, especially those used heavily. Drilling especially increases the rate at which cracks propogate, even when properly designed and manufactured (which most are not, especially not those done by someone other than the original manufacturer) You just can't get around the physics of the hole creating a significant stress riser in the middle of the disc surface.

* Cross Drilled Discs will last up to twice as long as O.E.M. rotors

Pure marketing BS, I'd like to see the basis for this claim.

* 40% Better Cooling, 20% better stopping, as well as Less Brake Fade and Longer Life

Compared to what????? lol. What metrics indicate 40% better cooling? 20% better stopping? Again, compared to what? Using Delrin for a pad and coating the rotor in teflon? Well, hopefully this is all true, because my K&N air filter really did give me 25 horsepower at the tires, so my car is so mad fast it will need the extra stopping power.

And Ferrari-Nick,

the sloted or drilled surface alows the gasses trapped between the pad and rotor surface to escape resulting in more friction and better stoping.

Bzzt, wrong answer, but thanks for trying. What Phil said is exactly correct. Modern brake pad materials, specifically the resin binders, have long been past the outgassing issue. We're talking several decades at least.

But! I will tell you what slots and holes really do help with on your brake rotors . . . What they do actually help with, is keeping the pad surface clean, they scrape it down on every revolution under braking. What this does, is helps prevent glazed pads from being a problem (usually this is only a problem when you have grossly mis-selected what pads you should be using) and it keeps foreign material from getting embedded in the pad surface. The downside to this is increased pad wear and build up of lining material on the trailing edge of the slots or drilled holes (this can lead to something that feels like "warped" rotors).


now tr0nic, I didn't say all this because I don't want you to sell these parts to people; I am simply wanting to educate people with the facts before they buy. The real reason to buy drilled and/or slotted rotors for a street car is simply for the looks. That's the only reason its done on the high end sports cars, simply because people like the way it looks. The stuff you have for sale here is good stuff, a qaulity base rotor, decent street pads at a really good price, but don't deceive people with bogus marketing claims. Just tell them its a good qaulity comparable replacement with a little extra bling thrown in. As for me, make my rotors plain, or at the most slotted only.

You, as the seller, must supply the data to support your claims. It’s not up to the consumer to prove you wrong.

[JonDoe]

I thought everyone on here only knew things about cars...... Good call!

[AndyMan]

wow.. a bunch of people who came out of no where just to post here in this thread... amazing...
anywho,.. to the task at hand :disgust:

i don't have the rear discs.... so what would i need to upgrade to get the full kit??

[tr0nic]

Yeah they both signed up and they completely tore me apart! Oh well.

You'll need the rear-drum to disc conversion... check the cougar how-to section on our website for details.

[Rara]

Check my sign up Date, it certainly isn't last week. I just don't post here much. I'm no stranger to the platform, or cars in general. I'm an admin over at CEG, I have 6 years of experience designing OEM brake systems, and I help build and campaign professional road racing cars in my spare time.

I see lots of BS claims from people trying to move product, and I'm just trying to get the truth out to people who may not have enough technical knowledge to discern it for themselves. tr0nic, I've tried to give you the benefit of the doubt as much as possible, because I know you are just repeating what your suppliers tell you, but man, you have to apply some thought to what you use to advertise your stuff. You're lucky I haven't dropped on the floor bar thread yet, I've been fighting with myself not to, because I don't want to destroy your livelyhood, but those are the most useless devices I've ever seen, short of the infamous "Tornado".

[AndyMan]

so.............. to sum this up..
are brembo brakes "better" then my stock brakes???? When i say better.. doest it have better specs then stock???
if they are better specs... good :)
if they are not... shame on you tronic.. :(
LOL

Brembo parts are held to very high quality standards (I have a couple friends that are brembo engineers, and I use thier brake parts on my race cars and street cars)
And here, "better" is a relative term. These parts will perform significantly better than worn out stock parts, yes.

To make a long story short, these are good parts at a good price, just don't expect the drilling or slotting of the rotors to do anything but look pretty.

and please, I don't want anyone to think I'm bashing tr0nic, the guy is just trying to make a living selling parts, he's not an engineer, he has to trust the ad copy his suppliers give him.

[EternalOne]

I have Brembo engineers that disagree with you, my friend. ;)

i can't believe this guy, lol. dude, tr0nic isn't selling some 3rd party off brand s#it. Brembo makes a good product, lol.


excellent price!

[azbobbybooshay10]

I had to actually laugh out loud when he said "They put slotted/drilled rotors on Porsches and Ferraris for cosmetics only." Oh my...............

Back to the OT, what brand are the pads that come with the kit? KVR's? Mintex? I'll be needing a high-temp application that doesn't fade or warp during extended heavy braking periods.

[tr0nic]

AXXIS/PBR will be the pads that come with the set.

[AndyMan]

i am not an expert on brakes or anything... but i was wondering...
if i had a set of your front brembo brake kits...
could i get some parts dipped in chrome???.. i was at a car show and show this camaro with some nice brakes... i didn't know if he bought it like that or had it custom dipped... here's a pic
http://i81.photobucket.com/albums/j233/Andyman4/DSCN0520.jpg

any problems that could occur that i would need to watch out for??
thanks

[CougarGuy939]

i cant imagine that having chrome rotors is good for stopping, heating, warping or chrome coming off not sure but it would be cool to look at not sure on functionality

[DarkCat00]

Maybe there's too much chrome or I'm not seeing the caliper. Maybe its a cover so you can't see how ugly the rotors and caliper is.:shrug:


http://i81.photobucket.com/albums/j233/Andyman4/DSCN0520.jpg

[mond12345]

You can see the rotor isn't chromed, just everything else is.

[AndyMan]

so functionaliy could be a problem?? :shrug:
this could be a project to work on for me... :)

[Rara]

I have Brembo engineers that disagree with you, my friend. ;)

You're telling me, you have Brembo engineers that are telling you, that drilling a rotor that was not originally designed to take advantage of said holes, and is borderline for thermal capacity already, will improve performance of the cougar/contour braking system in any way, shape, or form?

[azbobbybooshay10]

OK, to me thats a seperate arguement. I was under the impression that they were manufactured as drilled/slotted rotors. Your arguement makes much more sense now that I understand you're talking about taking regular rotors and drilling them.

tr0nic, are these predrilled rotors? Or will you guys be drilling them yourselves? I would have to assume the former, but I'll wait for confirmation.

[tr0nic]

I'm not drilling anything, are you crazy!!! That is a serious safety issue right there. They have to be made specifically as drilled and slotted, and not drilled as stock. When you drill a cold rotor, it completely degrades it's structural integrity... thus huge brake fade, really easy to warp, etc.

[arctichawk]

I know I'm in need of front rotors and maybe all 4 ... any issues with shipping to Canada ?
Rara got me thinking so I read some FAQ's on this product ... sounds ok to me.

[creativecougar]

Yeah....seriosuly everybody. If you're not going to buy, then :gtfo: There's no reason to argue or any bullcrap like that. If you want to ask questions or don't understand something, then keep it to pm's. That's what you're supposed to do according to the rules anyway. I don't wanna be a jerk, but I'd rather read two pages of info not two pages of arguing. Please don't interfere with other's people chances of selling an item. It would suck if you were trying to sell something and another member chimed in and told the potential buyer that the item was worthless (and I am definately not saying that in this case). So anyways, fellow Neco'ers....STFU!

[PREDATOR]

Hey bud, that chrome "rotor" is just a dust cover made to look like a rotor. Notice there is no caliper... they also make the blank chrome with no holes if that's what your looking for.

[AndyMan]

so that pad then is on the other side on that correct?.. basicly its just a chrome plate?

[tr0nic]

That is just a beauty piece... absolutely no functionality. I can't even tell if there are any brakes installed. I'd assume the caliper and rotor are behind the plate - but I still don't see much of a point in hiding them.

[rmeman]

is this GB happening or not ?

[tr0nic]

Sure is... it has been open for the last month or so. You can PM me for ordering information, or see the first post in this thread for details.
