Vented and slotted rotors can carry there own problems and usually cost more..
but yes its to dissipate heat more quickly.
unless you have done extensive mods for performance I would stick with OEM replacements...

I know this is an old topic, but the best way to get rid of rotor vibrations is to buy the premium/heavy duty rotors from the parts store or online with cermic pads. I do brake hard all the time in AZ and never get vibrations from the prem rotors
