Guys, this isn't hard. Compare the upper and lower ball joint sizes on the 2nd gen Camaro, ask CPP what the overall knuckle height is, compare it to the B-car knuckle height, check the spindle height, and compare the location of the B-car steering arm to the CPP steering arm and that'll tell you if it will work. Lastly, see if you can get the in/out offset of the hub face and that'll tell you what rims you could use on it.
If you want to keep ABS, you may have a concern about tone ring counts. I assume the C5 bearing assemblies have tone rings? You may have to have a custom rear reluctor made and installed (now's the time!) but that would allow you to keep ABS as long as the teeth count match proportionally.
