Wheels should be here by Friday I believe. As long as spin comes back with some good news on the measurements I will press on with the operation.
I still have not heard back from weldcraft. I think my best bet will be to just call them before I ship the wheels so I can be very specific about what I need.

Ok, I think I will get them on their way to weldcraft in the morning if FedEx ground is open. I think they are open till noon tomorrow.
I really have not heard much on measurements so here is what I came up with. At the worst I will need spacers.
I am going with a 2 inches on the OEM front. That will give me an 18x10.5 inch wheel. I could run from 275's through 315's, so I am in ET street and BFG DR sizes.
The final dimensions I am sending to weldcraft will be this.
If someone see's a major problem with this plan please PM or post by 10 AM tomorrow, Saturday.

Current Dimensions
18"x8.5 offset = 58 mm backspace = 158 mm
Please widen the wheels 2 inches so they will have the completed dimensions
18"x10.5" offset = 58mm backspace = 209 mm
18"x8.5 offset = 58 mm backspace = 158 mm

12" will work with a spacer.

I am excited about this little project. Now I start thinking about tires.
I am amazed at how inexpensive you can pick up practically brand new painted OEM wheels. And they are nice looking wheels too.
I may get another set and try the Z06 runflat size tire if this DR project turns out good.
Thanks for the effort Spin

I think I will wait for the wheels and mount them to see where they come to on the top of the fender. I would like to stay inside the fender if I can.

Well there is another problem. the 245/40/18 front tire has a fairly tall over all diameter.
I was thinking about running the BFG 315/30/18, but it's overall diameter is shorter than the front tires. This was a definite no no in a C5 due to AH/TC problems.
I assume it is the same with the C6??
Anyway all is not lost nitto 305/35/18 and the BFG 295/35/18 have a little taller over diameter. I am leaning towards the nitto.
Nitto actually makes a 305/45/18 DR that would be nice because of the taller sidewall but I think the over all diameter may be too big for the wheel well.
Has anyone heard anymore about MT making an 18" DR. It was supposed to come out this spring but I have not seen anything?
Any thoughts from the crowd??

The wheels if too wide will hit the control arms.

What kind of integrity do you think that weld is going to have? How will they get it to be perfectly balanced? What if the weld isnt perfect and your wheel separates? WAY too many what ifs to be putting onto a sports car with this much power.
Weather or not they can do it is not the question. Would I want to be driving my car with a welded extension in them...no freaking way.
