So i finally purchased a 2012 g37XS coupe, i have a pretty simple question, that i cant seem too find an answer for. Im just wondering if all 08-13 G37 had the same brake pad and caliper size for the sport package, I no that Z and the G are the same for sport package.

 

see blnewt's post below, sorry for misinforming!

 

Actually the AWD Coupe S pkg has the big Akebono brakes, it's the AWD S sedan that has the small journey brakes. Not sure why they shortchanged the Sedan AWD S but they did
Also the new AWD Q50 sedan w/ the S package has the big brakes now
If you have these calipers you've got the big brakes

 

Yes those are the calipers I have, so I can just order 370z sport pads for them calipers then? Only reason I'm doing this is the closest Infiniti dealer is a good ways away.

 

Those 370z pads will fit fine, the calipers/rotors are the same. There's also plenty of good aftermarket pads available. Stoptech Street pads are what I use, excellent bite but are a bit more prone to brake dust.
