so are the "new" dimpled-slotted better than cross drilled slotted rotors? i'm sure you guys have seen them and just wondered what your take would be. I think the dimpled ones would be good in the sense that they don't go all the way through and weakening the rotor, thus lessening the likelihood of warped rotors. On the otherhand, maybe the cross drilled rotors would disipate heat faster? or are there no big differences between either of them except for looks?

brake dust

I know a few guys with performance rotors and from from what they tell me is that they produce a more then normal amount of brake dust (or rim killer) on the rims due to the holes or slots slicing against the pad thus shortining the overall life of the brake pad itself. But hell, they do look cool though. I opt not to get any because of those reasons and also drive daily in Atlanta's stop and go (or pad/clutch killa) traffic. But everybodys situation is different. But takethis into consideration. -Peace

I'm not so sure about the fact that slots/holes create more brake dust. Brake dust is primarily created by the pads rubbing against the rotor, not the other way around.

In my opinion, the holes in a rotor do much more than dimples in regards to performance braking. What does that mean? This means after braking a few times, and the rotor gets hot enough after an average number of stops, stopping distances, and brake force, that it tends to alleviate the heat from the rotor better than stock OEM. For my own application, the stock rotors were turned before i bought the car. 2 months later, after some regular, yet hard braking, they warped. I traded them for x-drilled/slotted rotors and it's been 6 months under more hard braking and it has yet to warp.

Now, perhaps, I am lucky to have a good set of non-cracking x-drilled/slotted rotors, whereas I've heard the vendors that we all know have switched to the dimpled set.

I asked this same question on the other forum, but without looking at the answer, I would assume that dimple does no better than slots and definitely no better than holes in regards to alleviating heat. It may have not ruined the integrity of the disc, but I don't think it has anything to do with brake dust, that's for sure.

I am just on stock rotors and axxis metal masters. but i don't think the axxis MM would create that much dust. if it does, i'll just clean them off. my main concern is with the rotors. i just want to know if they are better than stock rotors in ALMOST all aspects.

I would say they are better, asianlegend had some good points in his post. Also since he owns a set and I don't he would be tha man here. I'm trying to know the real on this too.
Thanks. I hear the dimples have some same effect as the whole x-drilled effect, but I am highly skeptical on that. I may get'em on the rears, just to complete the look, but I'll have to really see'em to see how it would really look match to my already x-drilled/slotted set in the front.
