Yes, the Z06 rims will fit with no problems, if you don't believe that take
a look at every other C5 out there, they have Z06 rims. Blaaaaa, do
something different. You are correct to be concerned about staying under the
body, I had a set of after market rims that had just a 1/2 offset and they
stuck out past the rear quarters, looked like crap.

Just an added bit of information about the 2002 polished and painted wheel,
it's forged, all of those after that were cast. Just a little lighter and a
little stronger. You can identify them by the width of the spoke where it
meets the rim, they are narrower. I just happen to have a set that I run on
my 98 for sale. I actually like them well enough to put them on the C6 but
the big brakes killed that. Looking at the tire circumference they are about
the same although the rims are different sizes.

Just a thought, try a set of the C6 wheels, some are available from those
that are going to the high dollar rims.

If you are close by stop and we'll put the non-runflats and the 2002 rims on
and let you see how much it changes the ride quality and cuts the noise. I'm
under the street light on the Michigan-Ohio-Indiana borders.

Just curious, what suspension did you get? Do you still have the plastic
links on the stabilizer bars?
