haha you probably havent.
heres the end-all be-all on drilled rotors (i wish
)
DRILLED ROTORS ARE PERFECTLY SUITABLE FOR AGGRESSIVE STREET DRIVING AND WILL NOT BE A SAFETY ISSUE.
DRILLED ROTORS ARE NOT RECOMMENDED FOR TRACK/RACING USE HOWEVER IF YOU WERE TO USE THEM, YOU WONT DIE, THEY WILL JUST GET SMALL CRACKS AROUND THE HOLES. GOOD BLANKS ARE BETTER SUITED FOR THIS APPLICATION.
ok, now we can all forget this argument, right?

I have some cheap drilled/slotted (on the car when I bought it) and I WON't get them again.
They are total crap, warped like crazy, small cracks, etc.
Brake manufatures themselves say they do drill/slots just for looks alone, that is it! If you look at the physics/thermodynamics it makes sense why it is only cosmetic.
The best option is blanks then dimples -> slots -> drilled.
I will be going with brembo blanks or ATE rotors when I get around to it.

I thought it was funny that Tirerack has a disclaimer on the expensive drilled slotted Brembo rotors that states you shouldn't use them for track use.
I've seen someone recently on my local forums shoot a picture of a Brembo drilled slotted rotor from their daily driver where a crack goes right across the whole side of his rotor.

There's a not great photo (sorry it was taken with a phone) on the front page of my website showing a big crack in cheap rotor, one that was not drilled but slotted only. The crack doesn't even eminate from a slot--just a cheap rotor in general.
If the slotting is done well and correctly and uses a good rotor (all of which are issues with various rotors) then it's much better than drilling as we aren't exactly playing with rotors that were built with drilling in mine (even from Brembo) in stock sizes. One reason I'm using mostly ATE's now is they are "slotted" in a not normal way. There no points to act as stress risers, and the rotors have proven to be very tough too. And the slots are shallow not nearly as deep as others which maintains the intregrity of the rotor better. And they are coated too.

Now that your total confused with everybodys opinion.Call Sam Strano and talk to him and see what he thinks you should use.He doesn't try to oversell you,and generally he's a good guy.I have bought a lot of things from him and respect his opinion.Ask 20 people their opinion and you get 20 different answers.

ok, I have made up my mind on the whole drilled/slotted vs blanks debate, but I am wondering about what is the best kind of pads to use. Conventional wisdom tells me ceramic, but we have all seen what conventional wisdome gets us sometimes...
