Just an update. Rims are at the shop to be widened. Little issue with whether the rims were OEM. I guess this shop has had problems with some of the repo's and is not crazy about working on them.
I think I convinced him they were OEM and now I am just waiting to get them back. I am going to order 1/4 spacers, I don't want to go any further out than that. With a 305 tire I think it will look ok. I am trying to stay local for the chroming to save on shipping.
Right now I am still wrestling with the tire sensor issue. If I put in sensors then I will need a re program tool. Sensors and this tool really run up the price of this DR package. I may go with the technique of just taking my street tires up in the truck, so the computer resets itself when I am in the pits.
The issue really is, as I have been told on the forum anyway. That if you don't have any sensors in your drag radials you could be prevented from entering comp mode.

I think if one is trying to widen the entire set to run Z06 size tires then it should be 18x9.5 and 19x11.5.
Just a disclaimer, I am not sure if anyone has actually done this yet with a set of OEM C6 wheels.

That is really not what I want to do. I like a stock look on a vette.
I think the cheapest way to get the Z look and performance would be to buy the Z up front.
But to answer your question you could run 345's easy with a tub. I am sure there are guys on here that have already done this.
I really just want a stock looking wheel that will hold an 18" drag radial. If they made 19" drag radials I would not even be doing this.

Shuritte, maybe you can help me as I am pretty unsophisticated regarding wheels and tires - I have a C-6 with Z06 STYLE fenders from Breathless Performace - I was told the rear fenders have made the back 3/4 to 1 inch wider on each side (but closer to 3/4 of inch) - I have spacers on the back - I would like to put a 20 inch wheel on the back and a 19 inch wheel on the front - what is the widest wheel I can put on the front and back without doing anything and without really sticking out? thanks in advance.

Spin may be able to give you an estimate. He has done several measurements with the car under it's own weight. For your reference Spin said with a 19 inch 79 mm offset you could widen to 11.5 inches total. So that would indicate that a 19 inch wheel could have a maximum backspace of 8.5 inches before it will interfere with suspension components on the inside. Seems to me with your fenders widened you could put a very wide tire on if you have your offset correct or use spacers.

Ok, update.
OEM wheels have been widened 2 inches, the are now 18x10.5 with the original 58 mm offset.
They are on the way to the chrome shop as I type. The center caps are already at a plastic chrome shop, and I bought some cross flag logo's that are just like OEM.
Next wheel spacer's or adapters.
Right now I am leaning towards a 20 mm custom made wheel adapter. I can get a 25 mm wheel adapter that would not have to be custom made. I may go that route. I have to think this over a little. I should wait for the wheels and car to arrive, but I sort of want everything done by then.
Spacers are can be bought 1/4 to 1/2 inch. Wheel adapters can basically be custom made any size but for our cars come in 25 mm and 30 mm. I have to think this one over a little. These things are not cheap and I want them to be right.

Tavarez, hope you don't mind that I am adding to your thread. It is on topic and I think you are interested in this also.
I have ordered DR's Nitto's 305/35/18s for the rear. The tuner shop that is doing my intake and exhaust work are going to take care of the wheel adapters for me.
Anyone who does this I do have one suggestion so far. If you are going to chrome the wheel, just buy aftermarket chrome center caps, the cost to chrome the OEM caps was very high.
I will post pics when I have everything done and mounted.

This is the information the fellow building my wheel adapters asked for.
Corvette 5/120.65 mm bolt pattern, 70.5 mm CB, 12x1.5 Thread
I am having them made 20 mm thick. So I will be at the same place the stock rear wheels would set. With the 305 series DR's it should set nicely and give me all the traction I will ever need with my mods. All I have planned is intake and exhaust.
For people looking at this thread. Does anyone know if you can have no sensors in your DR's and sensors in the front and still get into comp mode and AH/TC off? I would rather not put sensors in these wheels if I do not have too. I am still not clear on this.

The deal is this:
If your car reads a zero pressure condition in even one tire, it puts the car into safe mode as per the manual. I found that the only way to realize this would be to try to turn at more than .7g's the car would activate the active handling and limit the performance. You have some time befroe the sensors missing triggers a zero reading at the dashboard and it is also unclear if the handling limit would affect the car's acceleratin in the 1/4 since you wont exceed .7gs turning at the track unless of course your track is the hiway exit ramp.

If you just want them to stick out a few inches you can just add wheel adaptors from these guys:
