Do you see these cars on the track with these rotors?
Drilled rotors are fine for EVERYDAY driving. Not track use.
Go google drilled/slotted rotors instead of sounding like an idiot.
And my sister's c230, comes with drilled rotors, does that mean she can go tracking with those too?

 

Calm down dude. It was just a fvcking question.

 

I'am calm, it's just ignorance gets the best of some people sometimes and they can't seem to hold back..

 

wtf are you talking about? Have you ever been to a track, or let alone seen a race on tv? Specifically the GT2 Le Mans racing which consists of these Ferraris and Porsches that you stated have drilled rotors for looks? It's strange how they race prep these cars and still put on drilled rotors? but what do I know, I'm probably just as ignorant as the guy you just flamed in this thread, but I guess that would make Brembo ignorant too...what the hell do they know about brakes right? read up and stfu before u post anymore nonsense http://www.brembo.com/US/Racing/LatestNews/06152007.htm

 

What is the difference between drilled and slotted discs?
Drilled Brembo Sport Discs will operate at a slightly cooler temperature than the slotted version disc because of the added air surface created by the drill pattern. Slotted Brembo Sport Discs are recommended when using racing brake pad materials or the vehicle is submitted to extreme braking duties such as towing or hauling heavy loads. Both designs were engineered by Brembo to improve pad “bite”, improve wet weather performance, continuously refresh the brake pad and prevent gas from building up between the brake pad and disc.


That is from Brembo's Site. Extreme braking would be used on the track correct?
Not from going to the dam grocery store. That's why drilled is better for everyday use (No track) And slotted (For track) Thank You for your added ignorance.

 

I'm really not sure how to argue against your statement, you state that "Drilled Brembo Sport Discs will operate at a slightly cooler temperature than the slotted version disc", therefore when you have a multi-million dollar race team on the line that "slightly cooler temp" will let you "slightly" brake later, and then "slightly" win the race which imho is the goal of racing. Thus, the drilled rotors seem optimal for track driving and therefore you see them on race cars, slotted however run cooler than standard brakes but are suitable for daily driving because they are less likely to crack than drilled. So what we learned today is: for daily driving with maybe some tracking, auto-x, etc. slotted might be a better option for most, but if you have the money and the slotted aren't enough for your driving style drilled rotors are the way to go.


And here's a link to one of my favorite production race cars that's made it to the street: http://www.supercars.net/cars/4372.html

...and guess what? It has drilled rotors! .... Those idiots in Stuttgart, joke's on them, slotted rotors are better for track/race cars

 

See the thread I quoted above... When you are towing or carrying heavy cargo, you need more brakes to stop, heating up your brakes, causing brake fade that would normally happen only if you were driving in heavy traffic or out on a very spirited drive. Slotted rotors will cool better, eliminating brake fade. But like pattyskin stated above, there is less contact area between the brake pads and the rotors, so your overall stopping power has diminished a bit.

If you don't know what brake fade is, it's a reduction in stopping power due to heat build up.


First off, their rotors are usually oversized, so although they're drilled and slotted, there's still plenty of contact area to stop the car. Second, their rotors are manufactured with the holes and have been tested and certified under regulations, not just drilled and thrown on the market by a middle man like Stop Tech.

It's when a second company takes the rotors and compromises their integrity by drilling that you'd have problems with cracking... but that doesn't mean all rotors that aren't drilled by the manufacturer are bad. If they did their research and measurements correctly, you should have no problem. But then again, who's to say the middle man actually put all that into drilling into those Brembo blanks? Are they ABE approved like Brembo's own drilled rotors?

IMO, if you get drilled rotors, buy from the manufacturer names like Brembo, etc... Those rotors were designed to be drilled, while other companies (ebay companies, etc...) took their blanks and drilled them. Then, the only thing you'd have to worry about is the loss of contact surface, resulting in sh*ttier braking, unless you bought a set of BBKs...
