I am trying to determine the correct brake parts for my 2013 G37XS. I am interested in replacing the rotors with slotted & drilled and a pad with OEM quality ceramic. I am having questions regarding rotor size. Short of removing & measuring them how can i determine diameter & thickness. I do not have Brembo brakes.
Any help is very much appreciated & thank you in advance

 

There are only 2 sizes. BBK and non BBK. So finding the size should not be an issue. Check on rockauto, autoanything, etc

 

320mm/12.6 in front rotors and 307mm/12 in rear rotors for base/journey/AWD G37 sedan models

355mm/350mm respectively for RWD Sport Sedan models

What are you looking for in terms of braking characterstics and use? Decent amount of options out there.

Blank, vented rotors are typically good enough for most applications.

Slotted introduces more wear to your pad with minimal benefit for most street applications.

Drilled introduces an increased likelihood of cracking your rotors (though most reasonable drivers will never cause that to happen)

 

Thanks for the info - that helps a lot. Wanted to do drilled/slotted for looks primarily. My driving is aggressive street - just looking for OEM equivalent.

 

If you have a coupe XS you have the big Akebono fixed-caliper brakes (355mm front/350mm rear rotors)

If your XS is a sedan you have the much smaller floating caliper setup (320mm/307mm rotors)

 

The OP posted this in the coupe section. Had I not moved it to the proper forum, it would have been obvious that he had the big brakes.

 

Thanks for the clarity (and the housekeeping)
