I have the OEM Infiniti Brakes and was wondering what the lightest aftermarket rotor i could use with them would be. I wanted to add it in conjunction with a new set of lightweight wheels i was ordering. I think the combination should be pretty pleasing.

 

High quality 2-piece rotors are the way to go. I have stop tech's Aero Rotors and they are much lighter than stock 4-5 lbs each i think. I am sure some sales person can give you the specific weight.

 

The stoptech 2-piece aero-rotors are only available for either the OEM brembo setup or their own stoptech calipers. There's no such thing as aero-rotor replacment for the stock non-brembo rotors.

 

Good catch. I missed that point and you are correct there

 

well what about the stillen xdrilled rotors?
