front should be 19's, might be able to squeeze them in an 18, however the design of the wheel has a lot to do with the wheels fitting over the brakes as well as the offset.

What width are you looking at, and what wheels? you cant always get the correct offset for 3rd gens, you may need spacers as well.

C6 zo6 wheels would fit, but you would need spacer

im tryin to get ripoff c6 z06s or regular rip off c6s.. with a 305 rear an 275 front. what should i get?

i believe the regular c6 has smaller wheels than the z06. They would most likely not fit the larger brakes

You will need atleast 18s in the front...Adapter thickness will depend on wheel offset.

so i just found 2 rear 18" c6 chromies with 9.5 width an 65mm backspacin with 295 dragradials what kind of spacer do i need for these? also since they are the c6 standard 5 spoke what offset should i get in the front to make life easiest

9.5" / 2 + 65mm / 25.4 Offset + 0.25" Lip = 7.56"

7.56" - 5" = 2.56" Adapter

With the brake upgrade you can subtract roughly another 0.3" for the thickness of the hub, so that leaves you at ~2.25" adapter.

I am not sure if the 295 drag radials will fit up front, but i've heard of people running 275s up front with little issue (minor rubbing at full lock).

If you went with replica c6 wheels you can probably find a wheel with a smaller offset, which will reduce the thickness of the adapter that you would need.

those are just the two back rims an tires i found.. i would need to find the front so i need a 2.25" rear spacer?

the 2.25" adapter would be if you ran those rims on the front. This site will tell you how to calculate the correct adapter thickness for the front and rear:
