Rotors sizes are 325mm front and 300mm rear. (This is pre-determined by all online vendors as long as you're buying 330i brakes. All other non Ms have smaller rotors.)
Brembo blanks or Zimmerman are the equivalent of the OE rotors.
For pads I recommend Textar (OE), Pagid or Jurid (all essentially the same). Another option is Akebono Euro which are ceramic pads. They produce virtually no brake dust but at the cost of less initial bite. Your call.
Use ATE Super Blue for brake fluid.
Thanks StraightSix! Now my next question would be where do you buy your parts from? Do you get it from a dealer? Which online vendors are good?
I did watch a few online videos and it seems fairly simple, the only thing im not sure of is the brake fluid bleeding part, if im only replacing the rotors and pads do i need to bleed? Im not touching the calipers.
Once again sorry for all the questions.
