Drilled vs. Slotted

**tatertot91** · 02-04-2009, 06:38 AM

I doubt i'm posting in the right place, but i wanted to see what peoples opinions were on brakes. Blanks, Drilled, Slotted, or Drilled and Slotted?

I say just slotted. the problem with drilling is after a while the holes start to get stress cracks around them. its pretty much unavoidable. Slotted and drilled looks good but thats about it.

Ya I heard that the slotted are the way to go. But I also heard that depending on the rotor brand, it will probably be done before you get the stress cracks.

The slots will help with the cooling and no cracks. I like it.

Purely for performance use leave the brakes alone, slotting is not as bad as drilled but still more risk involved.

Hum! Try R1Concepts.com and I have those on my SUV plus I haul a 7500lbs trailer for 2 years and no problem at all. They work amazingly well plus it's cheap and zinc coated so they don't rust. Try them you will not be disapointed and their brakes are sweet no noise and good braking.

I went with the Baer 6 piston set-up with slotted 13inch rotors. right around 2k but well worth the money.

Never seen a Ferrari or Porsche with slotted rotors. True about the cracks on drilled ones. I had slotted rotors and had to machine them twice. Then I bought white box cheap rotors and drilled them and have never had a problem. No cracks, no warpage, no noise and they get used hard. My short answer is drilled.

i got big cross drilled/slotted baer's on my car. they crack but i havn't cracked these yet and they have a ton of hours of race time. as far as drilled rotors crackin'. . .don't forget that smooth rotors crack too, and are more prone to cracking actually. they all crack eventually unless you drive like grampa, in which case none may crack. before i had my baer's i had cross drilled/slotted stock size and it's night and day difference in pedal feel. if you brake hard gasses build up between the pad and rotor and they float. . .slots and/or holes evacuate the gasses and you get a solid pedal/solid contact. of course i went through a few sets of those too. rotors just need to be replaced if you run 'em hard no matter what kind of trim you have on them.
