drill/ slotted rotors??

[tarmac2dirt]

Has any one have experience using the drilled and/or slotted rotors on there MJ, or any other vehicle. Its time for a brake job and was curious if its worth the double price of regular rotors. Thanks

I've tried them on the front of my MJ years ago and frankly noticed no difference except that my my wallet was lighter. If you want to improve the brakes do the dual diaphragm booster / master cylinder upgrade and swap to rear disk brakes. Much more bang for the buck.

Being that drilling and slotting rotors are techniques for improving braking in high heat, extreme performance racing conditions there's really no real reason to employ them on a Jeep.  

Lots of people waste a lot of money on those only to have pads that wear down faster and have a one time use rotor.

+1 for hornbrod's comment; get the booster upgrade and I'll even say skip the rear disc conversion and just properly maintain your drum brakes!

Do not get drilled rotors. If you choose to still get them get dimpled and slotted rotors.

 

Drilled rotors crack at the holes.

 

There is very little improvement with them though. I run them on my Cummins but I tow heavy and often. On a stockish MJ the juice ain't worth the squeeze.

For a daily driver it's a waste of money. If you want them for looks, OK fine, it's your money. If you race or have some serious performance driving aspirations, then maybe. For a daily driver, no.

I have slotted rotors but that's because they were on sale and cheaper then the stock ones.

Thanks for some quick answers, I will go ahead and by new regular rotors and some good semi metallic pads. I will look more into the booster swap, I know there are a few threads in here about this swap. Thanks

I did have some drilled on a Ford Contour. They did crack after some time. They might add some performance but I think there are other/better solutions. If I was 'racing' then I might go with them. Larger brakes or as was mentions rear disc. Also, do a search for various performance pads for Jeeps. Some rave about the 'Black Magic' brand. A bit pricey, but try them in the future.

Not worth. MJs aren't race cars. Dual diaphragm booster will get you closer though.

I had some on my Race RAM, and they did help. They helped bring it to a stop when going down the 1/4 and the sand drags.  

 

They did not last long. Sand would get in the slots, and tore up the pads. Mud also got in the holes and slots. 

 

You can't turn slotted rotors, so one time use. 

 

I would not buy em for an MJ, unless its raced. I defiantly would not buy them for off-road.  For daily driving, you won't notice an improvement.
