I did my research in various GXP forums, and settled on ACDelco pads that run about $45 a pair. Here is an example of some at this link http://www.brakepadwholesale.com/sea...rce=GOOGLEBASE. I now want to replace both front and rear, and was wondering if I should just buy the same kind, or is there a cheaper alternative that is nearly as good? $100 for new brakes just seems like a lot.
