But seriously... you can pretty much put whatever you want on there. On the street, cheap blanks from AutoZone will generally work just as well as StopTech drilled and slotted rotors. I'm running EBC USR slotted front rotors and have been very happy with them. Z1's rotors are inexpensive as well, and I like supporting quality forum sponsors. If you want some weight savings, go with 2-piece rotors - I like that Z1 has both front and rear 2-piece rotors (though the rears are more expensive due to the integration of the parking brake drum). They have options for blank, slotted, sprinkle slotted, or drilled and slotted - pick whatever look you like best. Personally, I would avoid drilled and slotted if tracking.
