Got'em on my Corvette but I'll be damned if my Jeep will ever travel fast enough to need that kind of braking improvement.

The problem is at the edges of the little bores. When you break hard and the rotor heats up, these edges cool down faster than the solid area and create stress thru shrinking when cooling more than the solid part. That's what makes these things crack. On slotted ones, yes, they dissipate water and gasses better, and wear on your pads faster. But for off-roading, they'd be less than optimal. The best upgrade for our application is a larger dia solid rotor and maybe dual- or triple piston caliper. But, I seriously doubt, anyone would like that kind of stopping power on a Jeep, if so, you'd have to go all the way and put slicks or Hoosiers on it and Porterfield pads...

you must not pay to much attention to German vehicles........

OK, so I've been sold on sticking with stock Advance Auto, AutoZone, or Pep-boys rotors, as someone said earlier.."use the money on making it taller", which is next..a RE 3.5 or 4.5 lift.
Now pads: Semi-metallic, Ceramic, Kevlar, Organic, what is the consensus on them?
BTW, thanks guys for all the input/advice...

I have them on my Benz, but I see no need to run them on my XJ. In my experience with my Benz, the pads do not wear any faster than a normal rotor would.

For a vehicle like the XJ cross drilled and slotted or even just slotted rotors are a waste of money!

they are designed to dissipate heat fast under extreme braking.. and its not true about them cracking that just hear say ive been running numerous cross drilled and slotted rotors on my evo for 3 years with race compound pads running SCCA events or just beating it up on backroads.... and ive never had a problem.. but as i was saying its completely unnecessary for an XJ you will never brake that much and that hard in a car like this to actually get any use out of them it will be pure show on an XJ and u cant even see the rotors...... pointless.... just get a regular rotor and spend your money on something more useful!

point taken!

Yes I have run them, BUT in my Trans Am for SCCA competition
unless you race your jeep in some sort of road race you will not see any benefits

semi-met. on solid rotors. let's think of it this way, for example: those big work trucks you see carry a ton of weight, and they all use semi-mets because when you have extra weight added to the vehicle, you are not going to wear them out as fast, and helps with braking. when we add the bigger tires, lift parts, heavy bumpers, tire carriers, winches, etc etc etc... you are adding a lot of weight. you could run ceramics, but even on a solid pad, with the extra weight, you are going to wear them down much faster. as far as i am concerned, organic pads are for hippies: haven't hear anything other than they perform like ceramics. and haven't heard much in the ways of kevlar pads either, so anybody could weigh in on those.

I vote ceramic. Thats what I have on mine, haven't had a single complaint.

Well, stopping from 80mph to 0mph heats and fades the heck out of mine... the truck actually starts stopping worse towards the end of the ordeal and I have to start grabbing lower gears to help brake.
Also, husteling thru waskhes, service roads will fade the brakes to uselessness...

Any one that says that better brakes are a waste of money needs a reality check.

all depending on the application.

and 80mph? didn't think there were speed limits that high anywhere in the country. unless you are ducking out from the po-po... lol

In case None of you have noticed, the topic has changed.... We are now talking about break pads. Maybe you should see what people are talking about, or finish reading before chiming in...

dont use slotted rotors or drilled rotors

and what exactly are break pads?

the pads that break dancers use, commonly refereed to as a cardboard box. (jk)
