Any experience/opinions welcome to help me make a choice.
did it for looks since i had chrome rims and polished calipers back then, but after couple years around 20k miles they got super noisy and would groan especially the rears. i've since put my oem rotors and pads on which i had saved and things are quiet and normal.
I don't know if it was because they were cheap chinese rotors or if because they were slotted they got noisy, or the pads but i never braked the car hard and the rotors had no signs of heat, were smooth never pulsated like they were warped. and the pads i had were basically full when I threw them out. if you have a street car i would just get napa premium or any regular blank from a local parts store. biggest thing is make sure whatever you buy does not need to be turned prior to install, or go through the hassle of measuring runout yourself when installing. the drill and slot i think is a lot of bs when they claim performance benefits.

Drilling a rotor is primarily for weight reduction. NOT recommended for street use due to the tendency to crack. Some people run them on the street but that is for looks they don't get any performance advantage from them.
Slotted rotors should not crack if they are machined properly.
