I've been having trouble replacing the brakes on my '08 G37S coupe.

Amazon has given me incorrect info as to what parts fit my car, and I'm going to have to return them. They gave me rotors 1+ inches in diameter too small. They also gave me standard-type pads rather than the bigger pin-type ones. Several parts stores locally have also told me these wrong parts are supposed to fit my car. Hell, whoever had the car before me had it serviced by someone who put the wrong parts on it too (my front rotors were mismatched in size when I bought the thing a few months ago).

Given all this, I've decided not to trust anyone's compatibility guide for this car, since even when you specify you have the Sport version, more than half the sources I've tried still give you the wrong parts.

If anyone knows the diameters for the rotors (front and rear) for the 08 G37S coupe (big brakes, withe the pin-type calipers, 4 cylinders on front calipers and 2 on rear) so I can make damn sure I'm getting compatible parts this time, I'd really appreciate the help.

Auto anything got my stoptech order right and a pretty sweet deal at that. Brad supplied the right part numbers and you can confirm that on their website. Good luck.
