Anyone have these rotors?

IMO they look better with the drilling...

How would the drilling affect performance? Pads wear much faster...yes?

Do these rust?

I was all fired up on getting those same rotors until I read this thread:

Here's some of the meaty part:

Crossdrilling your rotors might look neat, but what is it really doing for you? Well, unless your car is using brake pads from the 40s and 50s, not a whole lot. Rotors were first drilled because early brake pad materials gave off gasses when heated to racing temperatures a process known as gassing out. These gasses then formed a thin layer between the brake pad face and the rotor, acting as a lubricant and effectively lowering the coefficient of friction. The holes were implemented to give the gasses somewhere to go. It was an effective solution, but todays friction materials do not exhibit the same gassing out phenomenon as the early pads.

...Now, I'm not sure if I still want 'em or not.

Well guys whether or not you subscribe to the whole crossdrilling is evil theory or you are all about them I have some real world tests with these bad boys. My roommate bought the exact same rotors from the same guy off of ebay and installed them on his 93 accord. He is a delivery driver and puts close to 1500 miles on his car a week. He has had about 5 sets of stock oem rotors on his car and has warped every one of them. But these he has had on for approx. 8 months and so far they are kincking ass. He is hard as hell on his car too. Really uses the brakes if you know what I mean. Suprisingly enough there aren't even any spider cracks around the holes. I had a set of neuspeed crossdrilled and slotted on my corrado and even they got spider cracks around the holes. So my opinion is that when it comes time for replacing the rotors I am going with these for the P5. I have seen them for $200 for all 4 and that is a damn good price. Besides YES they do look cool.

Well, with downhill mountain biking, cross drilled discs are a usually a must. As your going down the hill most people constantly are braking, which heats up the rotors like crazy. I believe the hayes company said 300 degrees. The rotors turn a different color and are scolding hot.

Often times when this happens, on a non-drilled disc, the break pad material will form a little coating of gel, which- when flying down a hill at 50mph on a bike...is extremely dangerous.

I am just not sure if the same concept applies to cars. I figure the car's rotors must heat up faster, as the car proportionally outweighs a measely bike.

But, not many of us drive with the brake on, so I'm not sure it would help you much.

I do love the look, and as the ad says, the rusty rotors behind expensive wheels ruins the look.

Yeah,
Give the thread I started a good hard look. If you want form before function knock yourself out and grap the drilled rotors. If you need reliable brakes that perform well and still look different perhaps slotted rotors would be the better choice. All out performance? Just get some Brembo OEM replacements.

 

[ghetto waggon]

why wouldnt a slotted, drilled rotor be just as reliable as a slotted rotor?

The only difference I see is the rust factor (any OEM replacement)

and

Brake pad wear
(both more signifigant than OEM venteds)

You can argue this till you are blue in the face. The fact is that everyone is going to have there own opinion. also it heavily depends on what type of pads you are using. The holes were originally created due to the same reason mentioned above about mtn bikes. Not a gel but a layer of gas would form because the rotors were so hot they were vaporizing the pad material. with the pad material of today you don't have to worry about that as much. I am all for slotted and in my opinion having seen how these particular brakes have performed on my roommates car I am for the x-drilled too. Now if this world was perfect then someone would make a 2 piece lightweight slotted and vented 13" rotor for our cars and a set of 4 would only be say $400. But the world isn't perfect and so I'll take my $200 and have these bad boys on my car. The x-drilled really aren't going to be a factor for those people using their car as a daily driver(not enough sustained high temp to crack the holes) and hey even if you do a replacement rotor is only $50 a pop. Haven't checked OEM prices but they can't be much lower than those if at all. BTW have yet to see as much rust develop on my roommates as are on my stock rotors. But good point about pads because these are going to chew your pads up quicker than OEM. Imean if it means that much to you then spend the $1200 for the stoptech kit and brake till your hearts content.

Just thought of this.... One important thing to note is that you will not notice a dramatic difference with these rotors. Not saying you won't notice any change but it won't be a big one. To get better braking you need to upgrade the lines to SS and the Calipers to at least a 4 pot.

So is there any brake rotors that will not rust no matter what? I hate seeing that freaking rust. But I'm also not going to pay for rotors that are over $100 a piece either. So I'm probably screwed.
