Brembo rotors
http://www.autoaccessorystore.com/ho...izard=&s=&mid=
I need new rotors and I was thinking about going with slotted and cross drilled Brembo rotors. What do you guys think?
Any recommendations on good rotors for a decent price?
Your help is appreciated

the thing is unless you're getting two piece rotors all the other cast rotors are basically the same crap. cast pieces of iron... don't get very complicated. no vaning, it's just a hunk of metal. so get the ebay crap or the power slot, or the stoptech, it's all cheap and all the same.

djbrye,
First things first...I would definitely stay away from the rotors you mentioned in your fist post. Brembo does not produce a drilled & slotted rotor. There are many companies out there that purchase blank discs and do the drilling and slotting themselves, re-box them and sell them as Brembo discs.
A true Brembo Sport Rotor will be either Drilled OR Slotted...never a combination of both. They will also come in a Brembo Sport Rotor box, sold as a pair, and will be identified with a 5 digit part # starting with the number 3???? for drilled and 4???? for slotted.
If you are seeking a true Brembo Sport Rotor always check to see if the source is an authorized Brembo Dealer. When in doubt, feel free to call 714-438-1118.
Also, contrary to what many people post on these forums, drilled and slotted rotors do in fact offer a performance benefit. The main factor in a performance disc, even one of original diameter and thickness, is the quality of the disc. A cheap Asian manufactured grey iron disc, will always be a cheap grey iron disc. Brembo Sport Rotors are made of a higher quality cast iron than what is seen in most other manufacturers. This ultimately creates a longer lasting and better performing disc under extreme use.
Second is the benefit of drilling or slotting. Each offers a benefit that will be specific to the driving conditions and usage.
If you are currently experiencing fade that is induced by exceeding the heat capacity of the factory disc and pads...a Sport Rotor of equal size will most likely not offer any benefit.
If you are simply seeking a higher quality disc that will function with a more aggressive pad, braided lines and high performance fluid...it will tie the whole package together.
Drilled rotors are generally recommended for street usage only.
Slotted rotors are recommended for off highways usage and "track like" conditions.
Many of you have heard the rumor that "drilled rotors crack".
The fact is that All Rotors Crack. Even smooth or slotted disc's. As all rotors experience high heat situations, common with performance driving, the typical sign of wear shows up in the form of tiny hair line cracks. These hairline or spider web type cracks happen due to the repeated heat cycles that the discs go though during aggressive driving. The only time that these crack pose a problem is when they are large enough to feel as you rub your finger nail across the surface.
The reason that drilled rotors are recommended for street use is because the tiny holes in the disc do promote better cooling characteristics. In a track type environment this additional cooling actually accelerates those tiny heat cycling induce cracks and ultimately lead to shorter life span of the disc. On the street, where you do not have the benefit of long straight-aways and cool down laps, the additional cooling offered by the drilled holes, does offer slightly better cooling to protect the disc from over heating and possible warping. There are other slight advantages such as refreshing of the pad, and even minimal amounts of weight reduction.
Slotted discs are actually preferred in track type situations for slightly different reasons. The main reason is the effect of the razor like edge of the slotting. This edge will constantly scrub along the pad and ensure a fresh bite between the pad and disc upon applying pressure to the brake pedal. Also the disc will last longer without the additional heat cycling that you commonly see with a drilled disc.
Now...keep in mind that all of the above information is dependant upon have a disc that can handle the high amounts of heat created during aggressive driving situations. if you are exceeding the heat capacity of the disc and pads you will ultimately need to upgrade to a larger Big Brake type system.
Also commonly mentioned on these types of forums, "most people will never reach the limit of needing a Big Brake system". That is why a high quality disc upgrade, along with high performance pads, fluid, and braided lines, stand as a great starting point. After this type of upgrade, if you never experience fade, you will most likely never need to upgrade to a BBK.
There are additional benefits of a BBK such as unsprung weight savings, improved pedal feel and response, floating discs, shorter stopping distances, ect.
If any of those benefits appeal to you, there is never any harm in upgrading directly to a Big Brake system.

Even some of the 2pc. rotors on the market are also "the same crap".
There are alot of 2pc. disc's being sold as upgrades, when if fact the quality of the disc is sometimes lower than the factory rotor.
While the weight savings comes as a very attrative benefit, please do your reaserch on the quality of the actual disc and even the hardware being used.
Remember...your EVO already comes with a high quality Brembo Brake package. While it is still an OEM designed system (usually toned down to achieve longer life expectancy), there are ways to achieve more performance from that same system without drastically changing components.
the problem with what you said is if people are seriously tracking their cars they won't be buyin' the "same ol crap" one piece rotors and they certainly aren't gonna buy them for a lot of money. only the people that want their daily driver to not break the bank every time they replace their rotors with something that basically works just as well but NOT UNDER HIGH PERFORMANCE CONDITIONS!
the people that do upgrade will do their due dilligence to research... hopefully.
also... you only mentioned one benefit of slotting and drilling. the other things you mentioned were just ambiguous: driver usage; do offer performance benefit.
i'd also like to hear which two piece rotors are less capable than the brembo one piece rotors.

trinydex,
I don't understand most of you reply. I'll try to answer the best I can.
My post was indeed mostly generalized information. In order to offer specific answers, and to offer specific and detailed performance benefits, would require specific information relating to a specific situation or circumstance.
I know it sounds like I'm running away from giving a specific answer but brake upgrades are usually a solution to a problem. If you're experiencing fade...we find the source of the fade and offer a solution. If you're warping rotors…we find out why and offer a solution.
First, the advantage of a rotor only upgrade is minimal, so I didn't have any answers that equal "shorter stopping distances"..."increased heat capacity"...or anything major like that.
Drilled rotors offer slightly better cooling, the ability to shed water during wet conditions, small amounts of weight savings, and some pad refreshing capabilities.
If drilled incorrectly or used in a very aggressive situation, you may end up with premature cracking. I would use drilled rotors if you need to find a way to lower the temperatures on the rotor and pad during street driving. Maybe if you've experienced fade from boiling your fluid. Every little bit of cooling helps n a street environment. This all adds to the performance of the brake system.
Slotted rotors constantly refresh the pad surface, improving initial bite and maintaining consistent coefficient of friction. They also help to shed water and keep the pad and rotor free of debris. I would use slotted rotors in a track or track like situation to maintain consistent pedal feel and bite. Also if you run a more aggressive pad that requires slightly high temperatures to function at an optimal level, a slotted disc tends to remain more consistent temperature wise. I would use slotted if you are glazing your pads or if you intend on running a more aggressive brake pad. This also ads performance to the brake system for a different circumstance.
I think you may have been looking for an over the top answer with huge claims for "performance". Allot of companies out there today are great at making huge claims about performance and not being able to back it up. I'd rather make minimal claims that I can guarantee and make sure the consumer is getting the product he is promised.
As for my comment about the 2pc rotors...I would rather not mention specific names. The purpose of this thread is not to "bash" or comment on any one else’s product. I have yet to see a 2pc. rotor offered for the EVO that matches the quality of even the factory 1pc. smooth rotor.
Now, some of them do offer good amounts of weight reduction. And Brembo does not offer a 2pc. disc. So, if someone is looking to save weight, by all means, you can purchase any of the 2pc. rotors that are available.
Just keep in mind that (1) you are decreasing the thermal capacity of the disc (2) the quality of the actual disc portion may be lower quality and will most likely not last as long. That's why I mentioned that people should be sure to do more research than just accepting the claims of any particular manufacturer as fact.
Believe me...I love the 2pc. rotor idea for the factory Brembo calipers. I wish Brembo offered it for every vehicle that we produce OEM Brembo brakes for. It is one thing to chase the weight savings, but it is another when you are doing it by lowering the quality and longevity of the components.
Again, all of the claims about drilled or slotted rotors are dependant on the ability for that particular sized disc to be able to absorb and dissipate the heat created in a particular application.

triny-
i gotta say, i've come to side with gary on this.
stoptech, brembo, alcon, ap, dba- pretty much all of the brands i truly trust to know what they're doing with my brakes- none of them make a 2pc OEM replacement rotor, only full BBK's.
stasis was testing one awhile back, and after talking to beau at srm, i found that they came to the same conlusion that gary is implying, and that stoptech has verbalized at some point- they do not feel that a 2 pc rotor, *in the OEM size*, is capable of dissipating heat effectively in this application. period- too much mass is lost, and no amount of fancy vaning or anything else will make up for it. i gotta assume that's what everyone else has concluded as well.
stasis went with a BBK, using alcon calipers.
for my part, given what i've heard from multiple sources that i trust to know their sh*t, i'm automatically wary of any company which *does* produce a 2 pc OEM replacement rotor....

so for those that wish to buy one piece rotors and not beat the crap out of them. the same old crap will do.
for those who wish to put their brakes to performance use, they should research.
i believe you failed to mention that though the thermal capacity is decreased from a one piece rotor, the cooling technology/engineering is usually improved as the stock brembos are only a pillar vane design.
