most people do think that slotted and drilled don't do anything anymore since the pads don't give off anymore gases. when in fact that is not true. cross drilled can also save unsprung weight but it is so minimal that it doesn't make a difference so drilled rotors are useless. slotted rotors did release the gases but the main purpose was to wipe the pads clean to they don't glaze over. that is only necessary if you plan on really give the breaks a beating.
Since I am slowly building my car for autoX/track days i would prefer slotted brake rotors.
I am not trying to be rude but my question was which brand is good, not if i need them.
