I'm looking for a place to buy drilled and slotted brake rotors. Any body know a good place? ![Boggled](https://www.ranger-forums.com/rf/forum2/images/smilies/boggled.gif)

slotted > drilled and slotted
Drilled are pointless on a street rig and just an all around waste of money. Plus, there are other downsides like drilled = weak spot and can crack the rotor, but I'm too lazy to find links to comparisons.
I've ran Stoptech slotteds and Posi Quiet pads on mine for the last few years and absolutely love 'em! Just waiting on my 03+ rotors and a new better set the same Ceramic Posi Quiet's will be installed along with the Expo discs.

Alright someone correct me if I'm wrong. The drilled and slotted are to help prevent the build up of heat which reduces braking pressure. If you don't have an excessive build-up of heat then its not necessary. Sure if your racing auto-x with your ranger like some members have before then you might see a benefit. But for a truck that is on the street with mild offroad then it won't make a difference, and like Shane said can actually make a weak spot.

^ agree with the last two posts.
Also , since you live in the North , snow and ice can pack in the inner side of the tire rim , and when parked the heat from the rotor will melt the snow , causing it to drip into the slots and holes.Where it will re-freeze. The brakes will freeze making it hard to move the truck , and when it thaws , the water will also reduce braking.
IMHO drilled and slotted are only good for high temperature areas and conditions.

Like I said...I love my slotted small rotors('02 and older 4x4 11.2") with awesome pads. I'm bumping my rotor size up to the 03+ size of 12" and the same pads but bumping up to Ceramics instead of Semi-Mets.....on standard stock rotors.
There's no telling what difference I'll see between slotted vs solid vented. In theory, there should be a difference. But in real world conditions, NOT on an autocross circuit? TBD. But when those slotteds went on with those awesome pads, I was running freshly turned rotors with near new mid-grade Raybestos pads and the new stopping power was amazing. This was almost 3 years ago ish and like 50k agoish?
