GC,

Unless you do an add on Parking brake caliper or the Street Shop C5/C6 Drum brake conversion, there is not much to do.. Assuming you choose to keep the parking brake.

if you do the C5 fronts, I would suggest the Street Shop conversion and the C5/6 rears to match the front.

Interestingly enough, the C5 front Calipers have the same piston area as the C6 Z06 ( actually a slight bit more, the benefit you get with the C6 Z06 is a fixed Caliper over the sliding of the C5, the the piston area like I said is very close.
