Does anyone know the OEM part # for a 09 G37x front brake rotors? I need to replace mine but not exactly sure which ones I need to be ordering since it's the AWD model but would prefer to stick with OEM parts. Are the ones my car 320mm rotors? Any help with the specs and correct size would be great. Thanks for any assistance with this...

 

320MM front//307mm Rear

RockAuto has a good selection. Can't go wrong with Centric blanks.

 

40206-EG000 is the part number I get online, which has been replaced by D0206-ZA500. Cost online before shipping is around $80 each. A physical dealership may charge around $105 each, and good oem pads are likely over $100.

This rotor fits the front of all X model G sedans from 2007-2014. So G35xS, G35x, G37xS, G37x, Q40 awd sedan. The better option would be to explore Rock Auto or even Tire Rack for a rotor and pad setup. You can get a quality cross drilled and slotted front rotor set with properly matched pads for like $170 and up. Use this opportunity to upgrade to something better than oem.

 

Thank you both for the replies and recommendations.
