I did the same but only the front pads which came out to about $50 shipped. They perform at least as well as the stock pads but gone are the insane amount of dust and noise from the stock pads. Hard to believe anyone would pay almost $200 for stock pads when these are available.
I love my cooled seats. Nothing better than cruising with the windows down on a nice day with the cooled seats on high. I've found that turning them on the lowest setting during a long drive keeps my butt/back from getting all sweaty, too.
