Rotors and Pads VS Big Break Kit

[WILDHOBO]

I would stay away from drilled rotors. As they have a habit of cracking at the holes.

I’ve yet to hear that about z36 rotors, and I’ve had them on multiple Jeeps. And I use them.

I have run multiple set of Z36 rotors on my Tundra and JKU, never had any problems with them.

I’m with you. I think it’s a pretty broad generalization to say that drilled rotors crack. Maybe cheap ones do from certain vendors, but I’ve yet to hear about it.

I've seen too many drilled rotors crack at the track. So I won't use them. On my Grand Cherokee and Power Wagon, I use EBC rotors that are dimpled and slotted. On my 370Z, I use RacingBrake rotors that are slotted. The RacingBrake rotors are $500 each.

I was wondering about your comments, I'd heard similar anecdotal comments and knowing what I know about metals and such, I decided, ok, how much of an issue IS this really. I was surprised - but not - (bottom line, looks like you may have seen a lot of cracked drilled rotors at the track)


Do drilled rotors crack easily?
Image result for do drilled brake rotors crack
While a drilled brake rotor will cool much easier than a standard blank rotor or slotted rotor, the drill sites are prone to cracking. .
(from a performance site)

From an aftermarket brake company -

While drilled rotors have a lot to recommend them, they can wear unevenly and may develop cracks when used in racing vehicles due to the heat and temperature extremes of a race. ... Drilled brake rotors are fine for general use in street vehicles.

Which rotors are more prone to cracking?
For performance driving, slotted rotors have become the preferred choice because cross drilled rotors are more prone to stress cracking under extreme use.

Are drilled rotors good for daily driving?
DRILLED rotors are better for your daily driving because they are less prone to warping or getting high spots and they are usually easier on brake pads, but they do not perform as well under extreme braking as Slotted.


Best Brake Rotors for Street Performance

Pros:

If you live in an area that experiences a lot of rain, drilled rotors are a very good choice. They perform well in rainy climates by offering a good “wet bite,” hold up well over the life of the rotors, and deliver more friction and more bite than their slotted counterparts. The bite is better with these brake rotors because the drilled holes give the water a place to escape, thus drying off the braking system components when water is present. Less water means a better bite and improved brake rotor performance.

Cons:

While drilled rotors have a lot to recommend them, they can wear unevenly and may develop cracks when used in racing vehicles due to the heat and temperature extremes of a race. Drilled brake rotors also tend to wear in concentric grooved styles, which can look funny when the rotors are aged if the drilled hole patterns are not staggered. While this does not impact the performance of the brake rotors, it can affect the vehicle aesthetic and sensitive drivers may prefer to select a different style of brake rotor or else change out their rotors more often.

Drilled rotors are also a poor choice for race cars. They cannot withstand repeated heat and cool cycles very well, and will fail sooner rather than later as a result

A lot of guys I know that tow heavy campers have gone to using cryo treated rotors. A lot of trackrats use them too.

Were you on the370z.com if so I think I can recall your Z, sweet set-up, wouldn’t mind seeing a pic of it again. Sorry, not trying to poach the OP’s thread with this topic.

So my take on this is that good quality drilled and slotted rotors are perfectly fine for a towing Jeep, unless you race it. I’m pretty sure anyone that races a 3.6 JT will lose.

Yep. Were you on it?

I was, same screen name.
I like your ride man.

I used the Superchips TD4 to "tune" mine and I do notice a bit of a difference but still soooo SLOW LOL
I think ill be just fine with the Z36 upgrade

I don't know much about the Z36 package. I have to look into more.
