Which do you guys perfer better: slotted, cross drilled or both? And does the brand really make a difference on performance?

Thanks,

Mark

I have thought about getting These, but I have heard conflicting things about them. Some people say that drilled rotors are horrible and crack easily, but others say that they work great, and Brembo rotors are supposed to be some of the best. But for $250, there isnt much to loose.

that link didnt work for me?

Oops, I fucked up copying it.

I don't like the cross drilled, I've been very impressed with the slotted though. Power slot has slotted/dimpled config now, but I have not personally used them.

Unless your going from 120 to 0, 5 times a minute your probably going to see that same performance from the stock rotors (which are great) opposed to a power slot type.



The idea behind the slotted is to evactate the brake dust more effeciently so more surface to surface friction could be had, but it could be argued that slotting rotors also removes valuabe surface area that would help you get stopped quicker. Even with the small amount of brake dust.



Either way your probably not going to see a noticable difference between a new stock rotor and a new slotted rotor. If you do some road racing tho, that will be a different story.

While slotted rotors do assist in removing brake dust, thier primary purpose is to aid in removing gas which is expelled from the brake pads due to high heat from friction.



The process of making brake pads, in simple form, involves the powder, and an epoxy resin which are poured into the mold to produce the pad, It is this epoxy resin which creates the gas that in turn produces the characteristics of brake fade because the pad will actually "float" in areas and not produce full contact with the rotor when you apply the brakes.



For my money, slotted rotors are not a bad investment



Also it isn't a bad idea to use slightly worn brake pads to break in new rotors, after a couple of hundred miles go ahead and put the new ones in.

is it a must to get a let's say.... brembo than ones that aren't well known? will it make a big difference?

more than likely Brembo or a sub of Brembo did the R&D on the rotor, personally I run powerslot on my car and they perform beautifully. I don't see a necessity to run high end anything unless you have the cash to blow or need the performance parts for your application, i.e pro racing, etc.

cool.... thanks for the responses guys...... i'm planning on getting my brother (fikserxseven) new brake rotors..... hopfully the brakes will handle the power the will make when he gets it back.
