I own a 2010 g37x coupe, I ordered a power stop kit, but unfortunately when I went to install it, the brake pads we're wrong, I was sent the z23-888 pads which don't go to my calipers. I called power stop and they have no idea what pads to send me.

Anyone here know what front brakes I need to get?

 

The ones in the link are for a X Sedan, your X Coupe has 330mm front/330mm rear rotors

Here's a thread that may help to explain why an error may have occurred.

FWIW the rear pads are the same for the X Sedan (and base RWD sedan) and the larger X coupe rotors (and base RWD coupe), so at least you're halfway there

 

Ok thanks man, I'll pass that on to power stop so they can send me the right ones, from what I can see now, they sent me the power stop k114 kit, but they should have sent me the k2862 kit.
