Email from James at Weldcraft. Doesn't address everything...quote is for 18" wheel, but you get the picture.
"Hello Ron,
What we do is ...part the wheel on the inside and add a band of the size you want and then we v-groove and hand tig the wheels back together.
So if you want say a 2 inch addition, your backspace will change by the same amount.
The price to widen those up to 2&1/2 inches would be $200.00 per wheel for an 18 inch wheel.
The process usually takes about one week.
James"
Additional FYI.

So If I widen the stock OEM wheel 2 inches, to 18x10.5 will that make my new offset + 50mm. So the offset would be 106 mm is that right?

Yep, which puts that puppy way inside the car! I have no idea what the max we can get away with would be. I think Spin is doing some measuring this weekend. I'm traveling, so maybe he'll post up tomorrow!

Then you get back to sticking out from the fender again with a wheel over 10". Perfect combo may be fronts widened 2" with a 1/4" spacer...might just bring the wheel out enough to clear the suspension and keep it under the lip.
A conversation with the CCW guys would probably give us everything we need...max offset, etc. I hear their 11" wheel (don't know offset) with a 325 on the rear has about 1/4" clearance stock.

I need to see what Spin ends up saying on the measurements. But I am thinking a 18x10 would have a 95mm offset.
This may work with a 275-295 size DR. And I don't think it would stick out.
Can you tell I can not sleep tonight.

What do you guys think about a BFG/DR in a 315?
If the rim was made wider to a 18 x 11 you could slap a 315 on it and this would give us the widest DR we could fit in to the fender walls.
Traction would not be a problem then,unless you get in to the high horsepower range . I my 99 FRC they where able to handle the 640rwhp and 735rwtrq it was making and this was on a under sized rim 10.5 for this 315. I would do a set of 18 x 11 for track use and another set of 19 x 11.5 for the 325 run flats if we can get them to work.

I think that would require spacers at this point. But I really am just crunching numbers here because I don't have my car yet to check.
Lets see what Spin comes up with. I have some painted OEM's on the way being shipped tomorrow. I don't mind being the guinea pig on this one as long as I get some help from the smart guys.
The fellow from weldcraft has not got back with me yet. Maybe my email was confusing. It was sort of difficult to explain what I wanted to do.
