Its time for me to change my brakes and just need help finding the right brake pads. The dealer list the factory brake pads at $157 for the front which is pretty fair but are factory pads the best or should I go with an aftermarket pad, there are some Monroe Brake Pads for this car on ebay for about $60, anyone have any opinions about those pads. Please let me know. Thanks for your help.

Check here, they are Nissan parts, but I think ther are the same as the QX56. Factory parts at a discounted price. (Sponsor)
