I have a 2013 G37 Journey sedan. I will be replacing my front and rear brake pads soon with the Akebono ACT905. Will the ACT905s fit both the rear and front? Or do I need a different size for the front? Thanks.

These are the pads I want:

Different for front and rear

 

Just check out rockauto.com to get the exact specs for F & R. Here's a link to their brakes:
