I am goign to do a brake upgrade to aftermarket rotors.. My question is wich is better drilled or slotted? what are the differences and what are they made to do.. PLese give and information or opinions on why i should get one or the other... thanks...

 

Drilled and slotted rotors are simply designed to keep the rotors cooler by allowing gases to escape via the slots or the holes. Rotors such as these basically serve no purpose on the street, as your brakes are not getting hot enough to need to cool them off. You would be better off with a set of Brembo blanks. However, if you're into looks, go for them. Just don't be pissed when the rotors warp and you can't have them turned; $125 down the drain.

 

how would they warp??? might be a stupid question, but i am trying to gain information and see wich ones will work better.... also would you recomend steel braided lines and racing pad with them?

 

Is there a certain brake fluid that i should use, that is better then what i have...?

 

Modern brake pad compounds do not 'gas out' so the drilling and slotting is purely an aesthetic feature for a street car.

 

The rotors warp if you brake hard some/most of the time. Even if you occasionally brake hard, then part of the rotor will have more wear than the rest which will cause your car and steering wheel to shake when you brake due to the uneven state of the rotors. I didn't think I would warp my rotors cause I didn't think that I was that hard on my brakes but mine are warped and it sucks.
I would get the brembo OE rotors cause they are inexpensive, have plenty of cooling ability for street/some track and can be turned unlike drilled or slotted rotors which are a lot more expensive and are overkill for street driven cars and once they are warped, they are worthless. They are mostly for looks, IMO, unless you do a lot of autocross/roadracing, ie a strictly track car.
Also, for pads just get some good street/track pads like the EBC greenstuff cause you don't need the redstuff unless your car is strictly track since they need to heat up before they work well anyway.
And as far as stainless lines, take the risk if you want to but these are also a waste of money, overkill for street vehicles and IMO shouldn't even be used on the street. Do a search on brake lines and you will find some good topics about the stainless lines that should make you think twice about getting them for a street driven car.
Don't have any info about fluids, up for that.
sorry for long post, but that is my opinion.

 

Thanks alot for all the information... I knew there was a reason i always came here...

 

Slotted/Drilled rotors will crack over time, and then need to be thrown away. There is less mass in them, and that means less thermal capacity (which the whole purpose of the brake rotor anyways). A drilled/slotted rotor is less effective than a blank rotor.

EBC pads suck, there's just no way around it. Call andie at Cobalt Friction ( http://www.cobaltfriction.com ) for some advice on pad selection.

 

I dont actually have experience with ebc pads, I was just illustrating a type of pad to get and it was first in my mind. I have heard though that ebc pads aren't bad but that was just what i heard.

 

Then dont recommend them.

 

brembo blanks....
axxis pads

 

I just got Brembo Cross Drilled and Slotted With Axxis Pads, i hope they dont warp.

 

Axxis pads are ok for a street application. Anything that brakes 'better' is going to be a comprimise with dust and noise and rotor wear.

 

Sorry, I guess I should have said "get something LIKE an ebc greenstuff or axxis"
I was just trying to suggest a type of pad, not necessarily saying that these specific ones are great. It was more to say, "don't get a race pad like an ebc redstuff or another kind that is designed to be used specifically on the track as they require warming up to reach their potential." I say this cause most of use use our cars for dual purpose ie, street & track, so that is why I say that.

oh well

.RJ: do you have personal experience with EBC pads, specifically greenstuff? If you do, then could you tell me why you think they "suck" cause I am looking into replacing my pads soon.
Also, you said Axxis are "ok for street application," do you have personal experience with those as well? If so what are your thoughts on them for a primarily street with some track car?
It is helpful for everyone if you share your thoughts and elaborate on why you like or don't like a certain product, the way Tom (B18C5-EH2) does. Just a suggestion as I am here to learn from those who have more experiences, and I have found Tom to have very good informative posts.

Thanks
