Do some research, or do SEARCH on google.com

I know they don't do much for braking in our cars. Lots of people think that slotted/cross drilled are to keep the rotors cool. That may be so, but that was not what they were designed for. They are designed to get the BRAKE DUST out of there.
I remember when I first got my car, the dust was nasty, and since I'm getting new pads, I had cleaning the tires/rims all the time, so I wanted to cross drill them, also for the look as well.

From that day on, I'd never go for cross-drilled cuz they decrease the surface area.
The choice is yours. Looking good with less dust and not being able to stop the car or being able to stop the car and avoiding all the hassles later on.

FYI, I had seen a mod up 3rd gen RX-7 with cross-drilled rotors on 4 corners doing autox. The guy couldn't stop the car and there were sqeaking sounds during his hard braking. In the end, the car just plough thru the cones.

Just wondering why lots of the Porsche have these then?

For more details, here's a semi-satirical look at the 3 major groups of new Porsche buyers:
40%- Bought the car as an expensive fashion accessory, to match their Rolex watch, Gucci clothes, and $600k home in West Plano, Texas. Pronounces the name "Porsh". Does not really care how the car drives; also considered buying a Mercedes S500, but thought it was too conservative, and a Hummer H2, but thought it was too redneck.
What They Think: "Gee, those shiny round thingies inside the wheels look really cool!"
55%- Bought their car to fulfill their childhood fantasy of being a racecar driver. Thinks the car is the finest racing machine in the world, but doesn't really know anything about racing other than what they've gleaned from reading Road & Track, and never pushes the car to the limit because they might hit something and scratch the meticulously waxed paint. Pronounces the name "Por-sha" and believes they know all about performance, but actually know very little.
What They Think: "The cross-drilled rotors are a serious racing accessory that reduces brake fade! What is brake fade, anyway?"
5%- Porsche Club lapping sessions junkies who appreciate the car for what it is. Bought the rare optional performance suspension and optional racing seats. Really know what they have.
What They Think: "I wish they would stop using these %$^(*& drilled rotors, damn things are too expensive to replace."

um they work and fit great. cheap and they are brembo, im not even the seller. im just passing on this if you want to save money and even want slotted and x-drilled rotors.

the pic is not right. he has the 5 bolt, the pic is just a example.

Actually, I've seen touring cars with slotted rotors upfront and x-drilled at rear.
I am sure these type of cars have aerodynamically engineered the cars so that they can channel air onto the rotors for cooling via air ducts etc.
I know that a lot of big players like Brembo, Alcon, Stoptech, Wilwood are making their own rotos x-drilled & or slotted. Those guys have special manufacturing processes so that the integrity of the rotors wouldn't deteriorate. Plus they have R&D ppl spending countless hrs in R&D!
Nonetheless and in conclusion, if you've got the juice to buy those branded stuff, no problem. Most of us are budget minded and think in terms of "Bang for the buck!"

its all true and good, but our mazdas arent racers, the ones we drive on the street, even with turbos and nos they still dont have enough power to make a difference to use a better braking system. you get an NSX yeah but MP5 no. so even if you get slotted or x-drilled, you wont get them to that point anyways. they are just for looks and do the same damn thing. who cares. our cars really are just for show not for go. you want go get somthing else. oh and PseudoRealityX i dig your info you have, you have way more posts then anyone in here and you are very helpful. PEACE and THX

You can easily overheat your stock braking system to the point where more brake is needed, but not on the street. Anyone who's done a track day can attest to this.
From my trips to the Rolex 24 at Daytona, most of the Porsches do run the slotted front and cross-drilled rear setup, although ive seen all varitions of drilled, slotted, and solid at all corners. So I guess there is no BEST solution.
For the street, its definately not worth upgrading, but in some cases, crossdrilled or slotted may be cheaper than good quality blanks, so go for whatever your wallet tells you to.

However, almost all racers realize that if you use modern brake pads, holes and slots do NOT decrease stopping distances, reduce brake fade, or reduce rotor warpage... the reasons most street enthusiasts cite for running drilled or slotted rotors.
