my s13 is my 4th car, and on every single one of them had, at least once, warped rotors. This is probably because I brake pretty hard.

Anyways, I am in the market for brembo rotors, there are, from my undertanding, the following types:

1) blanks (oem replacement)2) drilled (holes for venting heat)3) slotted (I think I read this is to let the air hiding between rotor/pads out, also to prevent lock up?)4) cross drilled and slotted (mix of both)

I am thinking about getting brembo cross drilled and slotted rotors. I was wondering if this is for my application? HARD braking and all. I believe I've also read somewhere that slotted rotors are easy to crack, I've actually seen a photo of power slot rotors crack, is this what I might expect?

the only reson you rotors is warped maybe because you braked for to long which caused it to heat up and warp,same thing with the guy who cracked the rotor was braking to hard heated the rotor up and since the crossed drilled and slotted ones cool so fast they become britttle it takes quite a few times for this to happed,every little bit of hard braking makes cross drilled and slotted brittle(same with stock one),

Dont trip dude, I have had brembo cross drill/slotted on my car for a year with out problems.

It is the drils that can cause cracking, but if you are buying a quality rotor like brembo you shouldn't have any problem in that department, contraqry to what others have said.

If I could do it all over I would say F the slots and just get all drills. The slots will wear your pads pretty fast, and the drills help out pretty good with fade.

if it is a quality rotor like brembo you should be fine. I wouldn't get drills on another rotor.

Wrong forum

the slotted is to clear the brake dust away from the rotor.

I have had Brembo cross drilled and slotted rotors for over a year…no problems

good read,

Sounds like blanks or slots are the way to go

Thanks rico
