Regular, Slotted, or Cross Drilled

I had posted this question a while ago, but I just wanted to be sure.

Need new rotors. I'm at 68,000 and have had them cut once already. I know
that the factory rotors aren't the best. The question I have is what are the
best rotors I can get that will resist warping?

The last time I asked I was told that regular rotors were fine, but I don't
recall brands.

The first option is cross drilled rotors.
http://www.rocky-road.com/xjrotor.html
I know that they're supposed to reduce heat and brake fade, but I remember
being told that they can really tear up the brake pads, so the regular
rotors were better.

The other option that I found since then is slotted rotors.
http://www.truckperformance.com/prod...4=Brake+Rotors
They're supposed to be better then regular rotors and help dissipate heat
better then regular rotors, but I don't have to worry about tearing up the
brake pads.

Soooo, on that note, which do I want? If it's going to be regular rotors,
just please let me know where I can get 'em in NJ

TIA

Re: Regular, Slotted, or Cross Drilled

you got it the wrong way round :-)

Cross drill dissipate heat better under extreme conditions, slotted
"tear up" / deglaze the pad.

Re: Regular, Slotted, or Cross Drilled

Drilled rotors are for race cars where it's no issue to replace the rotors
at regular intervals since cross-drilled rotors are well known for cracking
where they are drilled. Besides, unless you're racing your Jeep and doing
repeated high-speed braking, they're a ridiculous upgrade that in my
personal opinion is unneeded on a Jeep.

Re: Regular, Slotted, or Cross Drilled

This is partially true, but it depends on whether or not the drilling is
done before or after the stress relieving process. Most drilled rotors are
drilled after, and that is the problem. I sell racing brake components for a
local company that manufactures 1000's of brake rotors, including some for
Winston Cup racing. the funny thing to note here is that most of the rotors
I sell are to short track oval racers who do heavy braking, and guess what.
No drilled or slotted rotors. They use a heavy vented rotor. The best
scenario for a typical Jeep would be a countersunk relief rotor. This is
basically a standard rotor that is cross drilled, but the drill depth is
just enough for the point of the drill to penetrate until the "hole is the
same size as the drill used. This is the best option if you are looking for
some type of drilled or slotted rotor to clean the pads and cool the rotor a
bit. But in all honesty at the speeds that most Jeeps are using repeated
braking, the cooling requirements are about nil. there may be some benefit
to prevent the pads from glazing, but the proper pads would all but
eliminate that. Most stock rotors will fail if cross drilled due to the
stresses added to the rotor unless they are relived afterwards. then they
will more than likely need to be resurfaced as well. All in all I agree with
Jerry here. The drilled rotors are just not necessary for an off road
vehicle unless it is raced, and even then it is questionable. Oh and another
thought. Wouldn't it be nice for your brake pads to have to deal with mud,
sand and small rocks plugging all those holes up as well?

Re: Regular, Slotted, or Cross Drilled

Very true, never though about the mud and rocks.

I guess I was looking into those because the rotors (Stock) that I have on
there now didn't seem to last too long, but I guess they did.

Thanks
