disk brakes

Which disk brake is better. The slotted or the cross drilled. What are the pros and cons of both?

for regular street driving, oem are just as good. The slotted and drilled ones are designed to cool off faster when driven extremely hard like in road course racing, where you're full on the throttle, then full on the brakes every few seconds. If you want them on a street car you can get whatever, because they'll both perform the same and you don't need em, so just get whichever you like the look of the best. Crossdrilled look better imo.

If you do occasional road racing, my opinion is that cross drilled are best. They have fewer cut outs, which means fewer places to crack from/to when they heat and then cool. Cross drilled are proned to crack, even the top dollar ones. Slotted do not nearly as bad.

if you want to upgrade your street car, look into getting some ebc greenstuff brake pads, they'll make a diff, rotors will not.

Hope this helps

most people upgrade their rotors for looks...

Neither are designed for long term street use. Drilled rotors spider web at the holes and cause warping. Slotted rotors eat up pads. Both reduce the swepted area of the rotor (less friction area). A quality rotor like a Brembo blank is the way to go match that with a performance pad and you'll be just as happy and still have extra cash in your pocket for a real performance upgrade.

I agree that most people that use them on street driven cars do so for looks but somehow convince themselves that there are performance enhancements as well. I have not seen any quantifiable studies that conclusively state they improve braking for street driven cars. In fact, most reports seem to say the opposite.

so its not really worth getting because i was going to get them mainly for looks and so they don't warp. I had brakes on my other car that warped from using them to much on the back roads...damn stop signs 100 to 0 multiple times is no good. i smelled something buring and got out and my brakes were smoking. But you say that drilled and slotted will crack easier so i guess i hold off on them. I was looking at the Brembo ones.

I'd would definitly agree with everyone else. Slotted and cross drilled not only crack, warp, and break, but they also wear your pads down much faster than stock rotors. I would also stick with the stock pads. Aftermarket pads like EBC greenstuff do nothing for you in city driving. It will actually take you longer to stop with them then OEM pads. The reason is they are made to perform at extremely high temps that you will never see on a daily driver.

i think that brake dust on expensive rims have a lot to do with the type of pad for the street, oem tend to leave a lot of dust just look at front wheels of cars and suv's on your drive to work. when i upgrade that will be my first thought.
