what one is better and why?

i like my slotted...i have the 15" extreme upgrades and they kick complete ***. ive read many different things about both types of rotors...i think the slotted works better..but the drilled look cooler

Slots are designed for racing applications as they throw the brake dust off the rotor very efficiently. They are however very harsh on pads and of course, they make a hell of a mess on the wheels from the extra brake dust.

Either way anymore they are both just for looks. The principal behind slotted and or drilled was for heat dissipation but the technology of pads has come a long way and neither is necessary anymore. Look at current high end race cars. Most use a solid rotor just due to the fact that there is more braking surface area. I have the AP Racing 14.25 inch 2 pc. rotors on my car with 6 piston calipers and when I bought them I asked for solid rotors and I was told that they werent available with this application and I asked why and I was told that the drilled and slotted sold better. I was told that I would have to contact AP direct to get solid rotors

BOTH! Get the best of both worlds...cross-drilled and slotted. That's what I'm getting

Don't forget to pick up extra wheel cleaner

x10000 to that^^^^^


my wheels get so friggin dirty.. (front wheel) yarg...

hmm with my rotorpros and hawk pads i really dont have alot dust....maybe i just wash the car to often

I have the drilled/slotted from R1 Concepts they work very nice and not that much brake dust. In the front I have the drilled 15" saleen big brakekit.

Reality. Slots and drill holes have nothing to do with heat. Simple physics explains that you can't remove heat by decreasing the mass of an object. Slots and holes were the way to rid brake pads of the gas that built up between the pad surface and the rotor on trans am cars. The pad technology in the late 60's allowed a veneer of gas that was burned off the pad to build up between the pad and the rotor. This drastically decreased braking efficiencies. Today, slots and holes do nothing except "look cool". Besides, what street car is running a daily road course circuit at 9000 rpms anyway? But they do look sharp.
