So after burning through my pads at 24K it looks like my rear rotors are pretty beat up and I'm thinking just replace them all together. the fronts look fine as well as the pads, what I'm asking is what aftermarket rotors are you guys using? Or are you just replacing with the Mopar ones? And I know that slotted and drilled are actually worse for the JK so I'm basically looking for opinions on what direction to take? Thanks-

 

Why are the drilled and slotted ones worse? I'm about to change mine to dimpled and slotted rotors.

 

from what I've read the JK doesn't benefit from them and they actually wear out the rotors/pads faster since there is less surface area actually used to stop the vehicle. This is only from what I've read and picked up from the few threads here and on other forums. I was initially going to go with the slotted PowerSlot rotors but have yet to pull the trigger due to this information.

 

My advice from years of racing cars that really abuse rotors. For your jeep, there really is no real performance advantage in the fancy rotors but if they are visable through your wheels, the dimpled and slotted will be just fine and do look cool. We use a lot of slotted rotors in racing to help deal with the off gassing that pads do especially when they are new, it also helps clean off the pads. They are more abrasive so the pad life is less but in racing we don't care. For a street car you may care.

Stay away from any drilled rotors as they are very prone to cracking as the hole creates a lot of stress risers that are prone to cracking. The only drilled rotors that Ive had last well were on a light weight car and the rotors were factory Porsche rotors. They just never seemed to crack other than the usual micro crazing you see from the extreme heat.

 

The best rotors I have used for stock applications are the Raybestos Advanced Technology Rotors. I put them on my truck and my wifes honda and pedal feel went way up!! They are powder coated black in the center to prevent corrosion and are a much thicker metal. They use a special compound. I will be upgrading my rear JK rotors real soon to these. They are $60 to $70 a rotor but worth every penny. NAPA also sells them but under they own name of Ultra premium. You can always spot them because of the black powder coated center hub. If they are not powder coated black in the center you got the wrong rotors. The JK rear part # is 780519. You will have to order them as they are generally not stocked but easy to get.

 

good info on the raybestos rotors. I was looking at Centric premium rotors heard some good things about them and found um cheap online I'll see what I can dig up on pricing for the RB's though.

 

I just found the RB Advanced Technology rotors part # 780519 on Amazon for $38.19 with free shipping!!! A scream-in deal!!

 

Nice! that's stupid cheap! Good find and thanks for the heads up. For that price I may as well upgrade the front's too!

 

why not just stick with the stockers, and upgrade to say some EBC brake pads.

 

Those that say slotted or drilled rotors are just for racing don't really know what they are talking about. It is all about dissipating heat. If you do a lot of steep trails, like the type found here in Colorado, you know how hot your brakes can get and the importance of maintaining stopping power. I put the TF big brake kit up front and Powerslots in the rear, with ceramic pads and ss lines all around. I've had the front rotors very hot coming out of some of the high altitude passes, but they always had the ability to keep me on the trail, even while towing an off road trailer. I cannot say this about the stock brake setup, which felt spongy and overheated regularly.
