I shopped for a complete set of pads and rotors for my KIA last fall. As far as I could tell, ACDelco and Raybestos come from the same source. I think Napa were also the same/similar, if memory serves.

I've also priced brakes and rotors for the Outlook. ACD rotors are cheaper than Raybestos, but Raybestos pads are cheaper than ACD. You may find its economical to mix and match.

The prices on the parts were cheaper at Rock Auto, but after shipping, Amazon became more cost effective. Just be sure to order at least a week in advance. My order was 2 wiper blades, 2 sets of brake pads, 4 rotors and 2 sway bar end links, and it shipped in 5 separate packages, over the course of 8 days. Wipers and pads were in box. A single rotor was shipped on its own. Two rotors and one of the sway bar links was in another box. Ect... At least shipping was free.
