With the staggered setup, there is no rotating of the tires on the C5. And my current tires are directional in nature, so swapping side to side isn't an option either.

AFAIK you never swap sides. On my 325i, even though they are same size F/B you still don't rotate.
P.S. How do you know a rotor is causing the problem?
If your tires don't have a directional tread, they can be rotated side to side without any problems. Directional tires will normally have an arrow on the sidewall that indicates the direction the tire should rotate. Not all performance tires are directional so you'll have to look at what you have.
I think it is the rotors since I replaced the brake pads in the last 5K miles. Easy job to do?
I had a pulse in my brakes that was due to warped front rotors. They are pretty easy to change out with the right tools and proper jacking procedures. The very first brake job I ever did was on my Vette. Check out the info on this forum and watch the videos on Youtube. I switched out the rotors ,and pads along with painting the calipers all at the same time.
If you can do brake pads then you can swap rotors. Its two more bolts for the caliper brackets and walla....they come off. Its most likely your front rotors that need to be replaced. They will "pulsate" coming to a stop light when they need to be replaced.
If you have directional tires you can take them off the wheels, flip them, then put them on the same wheels and then on the opposite sides of the car from where they were. The inner sides will become the outer sides, and they will be correct rotationally.
Why do that? If you're running a ton of camber or some crazy toe out setup that's wearing the inner or the outer of the tire more than the other doing this can prolong the life of the tires considerably. If you're getting even wear there however, there is no reason or advantage to doing it.
Before buying new rotors, buy a sanding disc for your cordless drill and go to town on your existing rotors. What people think is pulsing from warped rotors is most often just uneven pad deposits on the rotor face.
You need to take the front rims off and bring them to a tire shop where they will swap the tires side to side and re-balance them. You should do it about every 10K.
With normal wheel alignment our cars scrub off the insides of the tread way earlier than you expect. You can have the car re-aligned to not wear the tires so hard but then the steering is a little more "dead" - and then why are you driving a Corvette?
I've never had to do that with the rears.

They are the same price....go to the napa website. Take your pick. Drilled rotors crack faster. Blank rotors hold heat better and crack slower. Eventually if you do any hard braking...they all crack and will have to be replaced. Or go to pepboys. Think they have 10% off right now.

ok - good enough. Now what about rotor suggestions? Don't need/can't afford drilled and slotted so let's not go there.
Before you waste money new rotors try cleaning the ones you have. I started doing this a few years ago usually after a pad change but sometimes just when the rotors start pulsating.
Take the car up to about 60-65mph and bring it down to about 25mph HARD. Not panic stop - just HARD. Do this about 4 or 5 times to get the brakes really hot.
Then let them cool down by driving normally. Don't just pull over and stop. Let them cool down naturally.
You are burning and scraping the build up of junk from the pads off of the rotors. Half the time that is what is causing the chatter not the actual rotor.
Also - loosen and re-torque your lug nuts with a real torque wrench. Wheels and rotors now are a lot thinner than the old days when you could crank them down with an impact wrench. I think ours are supposed to be 100 to 110 ft/lbs. Do them in a star pattern. Give this a little time to work - like days. And always do this from now on. Especially after visiting a tire shop. Especially.
This might be a stretch, but I've seen it happen twice over the years. If the rotors are original and never been off the car they'll have a little star clip on one lug stud. Factory wheels will normally clear this clip. But sometimes a worn out factory wheel or a lot of aftermarket wheels will sit a little funny on that clip and the wheel will never roll true. That will make a slight vibration which will feel like an untrue rotor.
