Good point.

New rotors from autozone 25.99 if you get the cheap ones. They work great and you can spend more money somewhere it will make your truck faster or taller. I've never spent the extra coin on slots or holes in my rotors or anything. Never met anyone with those kind of rotors that didn't buy really expensive pads too. I think the really nice pads are what made them brake better. If you get the slotted drilled rotors put a set of really cheap pads on there and settle it for me.

great avatar friend, that boy needs a shave!!!!

partially true.....vehicles that possibly would need them have them......911, ferrari,mercedes etc.....they have the potential to see triple digit speeds, 100mph+ (or speeds to justify slotted rotors) you will have more than just brakes to worry about

Vented pads, made by who?

KTMrider

I run them, ive had them for about 20k and i like em. they do wear pads quick, but that could have been due to a sticky caliber on both sides. just my 2 cents

We use slotted rotors on our drift cars, They work a little better then stock, With stock pads and slotted rotors it decreased our 60-0 times by about 10 feet or so.

Where they make a HUGE difference is in wet weather, After getting your pads heated up and them rapidly cooling from the water they tend to glaze prematurely, The slots not only allow water and exhaust gases to escape, But they also scrape a slight amount of everytime you brake which gets rid of the glaze and keeps the pads fresh.

You will have increased pad wear ( not that much more then normal ) but you will have an overall increase in braking power and reliablilty, Especially in wet weather.

As far as cross driller rotors go stay away from them, When I used them them they cracked badly from hole to hole, It looked like a game of brake rotor connect the dots.

If you are set on getting an upgrade rotor only choose slotted or dimpled otherwise you will be replacing them soon again.

Also if you are gonna upgrade pads also check out EBC they have the best pads for the price as far as I am concerned, I'm not sure if they make them for the XJ's but if they do I highly recommend them.

Hope that helps,

well im gonna add my 2 cents cause i have cross drilled and slotted rotors and this is why. i tow a trailer long distances on the highway and wanted the cooling efficiency of cross drilled rotors for towing applications, since 70% of braking power is supplied by the front brakes. its true that poorly manufactured cross drilled rotors have a tendency to crack, but i myself have never seen it happen except under extreme heat conditions. i also chose to get slotted because they clean your pads preventing glazing, but also cleaning any dirt, rocks, & mud away from the pads during outdoor romp sessions, which prevents brake squeel and rotor damage due to a foreign object ( a lil pebble) in between your rotor and pad.. does eat pads though...

i think meyle. a buddy gave it to me to try. i think i gave him 40 bucks for them. they do keep the rotors free of dust though.

I know that the stopping performance doesn't justify the price difference. Plus, pads wear extremely fast. But, if you take it easy on the brakes, that may be negligible. I do like the looks. If that's your thing, sure, why not. But, I've never seen a Jeep that exposed it's rotors...? Just sporty cars with over-size wheels? BTW, there's some good articles on the 'net on slotted/cross-drilled rotors.

SHO_91

There's special fab work for venting rotors and pads, no more than ducting that directs air flow to rotors/pads/calipers. If you're handy, you can even do these yourself.

Tural

i'm a machinist, and i can guarantee you that you will need to heat treat that rotor if you machine it. otherwise it will definitely crack.

i say if you want better brakes run a bigger rotor and caliper. more surface area the better

Tural

he'll probably have to mod the caliper bracket to run bigger rotors. and a set of larger wheels. upgrades are fun.

swap to wj outer knuckles and run its brake setup with a dual piston caliper. 12in brakes are cooler. also alows for true high steer.
