Drilling is from the old days for out gassing. Modern brake pads do not need this. If anything just go slotted. The slots do not go all the way through and help clean the pad. Your pads will wear faster though. Like someone else said, Porche rotors are cast with the holes. Drilling all those holes also reduces your surface area for cooling.

no it doesnt. they're CAST with the holes in them.

Re: Re: Re: Opinion on Slotted Rotors
Yes, I know this.
Yes. It is when you make a series of stops from certain speeds to allow the pads to "bed" with the rotors. This should be done after you install new pads and rotors. I forget the exact speeds and how many times you do it. But I think those insrtuctions come with some pads.
No, not really. But, I would have the rotors resurfaced. Resurfacing pricing varies. But it shouldn't be any more than $30. And depending on how hard you drive your car, the rotors may only be able to be resurfaced once. Rotors actually wear down so there will be a point when there isn't enough material left. Then you have to buy new rotors.
I still think the drilled one look tight and am going to buy a pair sooner or later...
Then, if I only want to change the rotors for streets use, I guess slotted ones are the way to go, right? Keep it in mind that, I don't want the squeal sound but want to improve the brake to its maximum.
BTW, is that the squeal sound actually coming from the changing of pads not rotors? right?

The squeal is usually from the pad. Sometimes dirt can get lodged between the pad and rotor and that causes the sound as well.
But some pads make that squealing noise and it's normal. If you were to use a racing pad on the street, there is a good chance that they are going to squeal really bad.
I have EBC Greenstuff pads waiting to go on my car. And I had Hawk pads on my old GT with no squealing at all. Although some say they have squealing with Hawk Pads.
My stock pads have been squealing ever since the 6,000 mile mark.

No problem. :beer:
And it really depends on your driving habit's. So I can't give you an accurate answer, sorry.
And FYI, I said it before......I've been told that a rotor that is both cross drilled and slotted is the worst combination you can get. Don't know the exact reason why, but that's what I've been told. Just something to think about.
Personally, I like the looks of cross drilled better, but I would probably go with slotted just because of the cracking concern with drilled.
Again, it somewhat depends on your driving habits. And I'm not sure if slotted or cross drilled eat away your pads faster. I don't see why they would. I would suggest you go with Brembo slotted rotors and a good quality brake pad like EBC or Hawk. Can't go wrong with either of the three companies I just mentioned. :beer:
Also, if you want to go an extra step, get Stainless Steel brake lines. I believe they are about $80.
