Sweet. Did this job last week, took it out for a track day weekend, and HOLY **** THAT'S GOOD.
Breakdown is C5 calipers from Rockauto, 18FR1853/4, $234 for the pair. Specified no logo, came with the corvette logo, ground it off with an 80 grit flap disc and under paint, you literally cant tell.
GT500 rotors from Summit, got the raybestos 680497PER, $181 for the pair
TCE Zack kit, $194. Need to double check my front line routing now that they've been used for a bit, but the lines are nice and came with all the hardware. On the front brackets, the ones that hold the junction of the hardline to softline, the holes for the bolt and the guidepin weren't very precise, I'd advise re-bending, grinding, or drilling before you take the old line off and have brake fluid dripping everywhere while trying to make it fit.
I went with expensiver race pads from Hawk, HB247S.575 for $264. If you're not tracking your car, go with a street compound from a normal company. These are expensive and loud, but holy cow do they stop hard, and I haven't experienced even a hint of brake fade yet.
And of course, the brackets from Gerald Irwin, who is easiest to find on Facebook. $170 got me a pair of very nice looking brackets, anodized, with appropriate hardware for attaching the corvette caliper. You'll need to grind a little of the spindle ears, I just made sure I could get a piece of paper between the spindle and the bracket.
So for a total of $1043 and a few hours of work, it feels like I've increased the stopping power of the car by at least 60%. More importantly for my 20-25 minute track sessions, I've increased the heat capacity of the system and no longer need to take a chill lap in the middle. And it fits inside the stock wheels, wheel weights and all (your mileage may vary). And most importantly, it looks great. Now I need to order the matching rotors for the rear and some fresh Hawk HPS pads to keep up.
As far as the unused inner strip of the rotor: You're getting the braking force farthest from the axis of rotation, which has the most leverage when it comes to slowing you down. You're also getting the most out of the surface area of the rotor, since Area = pi*R2^2 minus pi*R1^2. If the visual is really that big of a turn off, maybe get the GT500 caliper too, make your own custom bracket, and then get bigger wheels because it's probably thicker than the corvette caliper and won't fit between the rotor and the stock marauder wheels.
Anyways, 10/10 recommend
