To all:
AS the subject line says, I have a 2010 G37 xS sedan, anniversary edition. I need to replace the brakes and rotors. What I need to know is what size rotors are on the car? 320mm, 330mm, or 350mm. I believe the 350mm only came on the real Sport model. Not the xS (sport appearance model) that I think is on the Anniversary Edition xS sedan.

I would appreciate any input before I try to order these things. I don't want to order the wrong ones and and have to ship them back and have the car laid up for a week or two (it's the only car I have).

Thanks,
Augie

I believe you are correct. The xS had stock sedan brakes while the S had larger rotors and calipers. I have an 11 and that is one of the reasons I purchased the S model, though the all wheel drive was attractive. Can't help you with the rotor size though.

320mm front rotors on the sedan AWD Sport. The AWD sport didn't not get the bigger brakes. The 330mm rotors are for the 07-08 G35 sedan sport and all G37 coupes.
