Searching for the right brake setup, Brakes Options

[94celi757]

So i did some searching on the forums and came across a little info on slotted vs cross drilled and slotted rotors, now before i have this thread in a war going back in fourth between the two, now i know that many say to get a slotted rotor with some nice pads, and some say they have drilled and slotted, me asking around it looks liked drilled and slotted are more for looks although the holes are great for wet weather and the slots emit gases, but i hear that these are more prone to cracking and they are the least reliable. Im looking into getting slotted rotora rotors with some ebc pads, between the red pads or the ultimax pads, let me know what your experiences have been with the two, i know i will save money if i get some brembo blanks and get some nice pads.

Well, Porsche has its rotors cast with holes -- they're what drilled rotors aspire to be, except drilling greatly weakens the structure of the rotor.

The offgassing issue is a non-issue, unless you're using 1950s brakepads. Modern pads as a rule do not offgas. Glazing, which is the point of slotted rotors, is also much less of an issue. Actually, if you're getting glazing, you're using the wrong type of pads for your application (e.g. street pads while on the track).

They do, but they develop cracks too. Heck, my best friend has a Baer Track setup on his Z28, and those came drilled/slotted from Baer along with being cryogenic treated. Guess what? They were stress fracturing in 5k miles at the holes. Cross drilled are more for dedicated track cars that are looking for reciprocating weight savings that don't depend on the rotors for daily run of the milll driving. And the show crowd. Stick with a slotted or even a good quality blank, you'll be fine.
