alright i have seriously heard everyones arguement over drilled and slotted rotors over autozones oem one's with the lifetime warranty. i baught them on ebay a few minutes ago for a good price with 4 ceramic brake pads.
i have been hearing they dont last long and that all waste more money buying them when instead i can just buy one set and be good the rest of my cars life. what do you guys think i personally like the look of the D/S rotors and dont mind paying a little extra. did i make a good choice and is it true that they really dont last? does fwd effect any of thease arguement? any feedbck is helpful

The way I see it, drilled/slotted rotors will just eat your pads faster, and I've seen pics of low quality drilled rotors forming cracks around the drilled holes. Supposedly helps dissipate heat and "shaves" away any braking inhibiting glaze that may form, but you also lose surface area for the pads to bite.

I personally like the look, but I'm not willing to drop hella cash on the rotors, nor would I want to replace pads more often.

yeah pretty much you will have worse braking performance than a solid rotor. the only good drilled rotor is one that the holes are cast into and not actually drilled. exotic cars have these all the time, but dont let that confuse you. the rotors are nearly double the size of your civics, and the holes are actually required for cooling. stick with oem rotors on the small cars and you will be more than fine. remember these are brakes and are one of the most important parts on the car. dont put your life on the line for some stupid holes in a cheap disc.

i have run drilled rotors on both my truck and my civic has them now to.
I really havent noticed a difference on the car but the truck stops better in water

The only advantage of a drilled or slotted rotor is that they dissipate the heat much better than solid rotors, with that said if you are going to be doing only street driving it won't make to much difference to have drilled/slotted rotors but if you are racing, braking hard cornering, accelerating braking hard and cornerinf again, then it takes a lot longer for you to develop "squishy" brakes which is where the brakes are unresponsive due to such a large amount of heat build up. But you need to makes sure you get quality ones ,because they have holes in them that are more prone to warping and developing cracks

Personally if I could afford them I would have drilled rotors all the way around 1. Because they look awesome and 2 because yeah you will have a bit better stopping ability

A relevant discussion was going on today on CL. I know electrickytech, he is a longtime racer. Knows his stuff. Check the whole thread.Yeah, I know it's CL so there is some BS too.

Why do they drill holes in rotors?

"A brake pad will start to smoke as it gets beyond its operating temperature, the layer of gas emitted will act as a lubricant between the two friction surfaces and will be manifest as ineffective brakes."

Hmmm. "...the layer of gas emitted will act as a lubricant between the two friction surfaces...."
The holes and slots let these gases out so the pads can maintain contact with the rotors.

"The heat is dissipated from the pad by the discs %u2013 a vented disc has a central channel which increases the surface to air ratio of the disc and created better and faster cooling. Drilled discs also increase the air ratio and along with grooves help to prevent a gas build up between the pad and the disc and keep the pads %u2018clean and sharp%u2019."
