Good idea or bad for an offroader ?
Opinions on both?

I have limited and little knowledge of the brakes your talking about, But I believe slotted and drilled brakes are mainly to cool them off faster and to get rid of some of the dust. I don't think there really necessary for off road wheeling, maybe off road racing. But that's my 2 coppers. But there not bad. Plain or slotted will still stop you.

See my problem isn't really offroad stoping because brakes get wet there and there's notice you can do to stop all that great I'm more talking about when you bring an offroader on road and need to stop good again no to mention the wj has pretty crapy brakes

Man this iPhone autocorrects way to much there's no chance of stopping very well if your brakes get wett and muddy offroad so that's not really my concern

I have them and love them I got the biggest rotars with zinc and the ceramic pad combo front and rear. They are really nice when its raining out because it pushes all the water away. Do you need them no, you want them because there awesome.

I've heard that drilled are no nos because when water gets in it causes cracking

At least that's what my buddy is saying I think he's nuts tho

Drilled rotors dont crack because of water. They develop cracks and fissures around the drilled holes if they are of low quality and the holes are not chamfered.

So the ones on rock auto for the wj anyone know if there the good ones there about $60 a peice when I was looking ( I warped the crap out of my current set and the squeaking is killing me with this nice weather all I want is it gone so I can open my windows) and I want a more permanent replacement that won't warp as much

Exactly what GI-Jeepin' said with inferior designs will lead to the breakdown of your rotars and pads. But that is with any cheap rotars you will warp them in 20/30k miles. Also if you use mealtic pads they squeak really bad, I am using ceramic. This is the guy I use for my Jeep, he is one of the very few people who make a full sweep slotted rotar. Reason behind it's the best for removing water and mud from your breaks. http://stores.ebay.com/atlautosports

That's a heck of alot better price for the wj I was looking at 230 ish for rock autos these any good out side the websites own words I mean they look amazing

They only other company's I have dealt with has been Brembo and http://www.r1concepts.com/
If you do not go offroading I would go with R1. Otherwise try to get a full sweep rotor. Found another Picture of my rotor. I just realized my Firefox was auto correcting rotor to rotar.

Here's my setup.
Rototech Rotors
Mopar Replacement Calipers
Ceramic Pads

Stops my 32s with no problem. They've been on for about a year now and they're great. I've heard plenty of good reviews from guys who have had the rotors on their vehicles for 5+ years. A couple of my buddies with XJs have the same setup as well.

Nice never used Rototech Rotors but herd good things about them. +1 on Ceramic Pads.

The purpose of the slots and holes is to allow hot gases to escape away from wherethe pad and rotor meet.

From what folks have said your just asking to get dirt and grit filling those gaps, causing more issue than it solves.



I can lock up my 33s, and I have a crappy Renix braking system.
