Well, I installed the rotors today [along with the new caliper brackets (thanks, Bill Jenkins)]. The install went just as smooth as any rotor and pad replacement could.
Thank you to everyone who found out the information that said that this could be done.
Thank you to Big Jim (the first person who I remember posting this) confirming that the larger rotors would fit under the factory 15" wheels [one thing at a time

].
BTW: The EBC grooved rotors are a well made product. But, I believe that they have a design flaw. The grooves cut into the faces of the rotor extend all the way to the edge. When the rotor heats up during normal use, it warps. My rotors would return to 'normal' after an extended cooling period. They would warp again after just a few gentle stops from as low as 40 mph. They were much worse from freeway speeds, especially if I needed to stop quickly. I would buy EBC rotors again, just not the grooved ones. (I had the rotors on my car for 5 months, 8700 miles. I have had the warping problem for about 2 months.
