Custom Backspace & Offset ...
... on stock wheels? I've searched for awhile this early morning. If I didn't dig far enough, my apologies.
Please correct me if I'm wrong, or point me in the right direction if I recall correctly. I thought I had run across a link of a company who made custom wheels (backspace/offset/bolt spacing) from stock wheels.
I have a 1969 Stingray that I will be fixing up to drivable status this summer. It currently wears (4) 15" wheels now, all wrapped in 295/50-15 sized rubber. The fronts are too wide (rub swaybar and inner fenders) and the rears don't fill in the custom L-88 flares.
I came to the conclusion that ZR-1 sized 275/40-17s up front and 315/35-17s in back would help me out in both form and functionality. Everyone uses A-mold wheels and I figured I would be different in going with the 1990 ZR-1 wheel look.
My goal is to fit 1990 ZR-1 wheels onto my C3 without the use of adapters. Does a company exist who can do this for me if I provide the appropriate measurements?

Those are definitely interesting wheels, and I actually stumbled across them yesterday. I am presuming that you're selling them since the city/state matches.
What are you looking to get for the two wheels? If you don't want to make it public knowledge, send me a private message. Also, what price are you looking to get for two fronts?
There are just a few things that hold me back.
Cost: Right now I'm saving money for what I'll eventually purchase.
Rarity: I'm not sure that I want rare wheels on my Stingray for what would be used in daily driving.
Fitment: I don't know yet how C4 wheels fit on a C3. I've got flared L-88 fenders in the rear, so that's not a problem. Only backspacing and offset are the real issues.
I could have sworn that I have visited a website in the past, where it showed stock Corvette wheels all with different backspacing and offset dimensions.

Got your e-mail and replied.
Bummer about the website, I wish someone else knew about it. I hate sounding like I'm
Maybe I'll stumble across it again in my journey through the Internet.

The 5 spoke wheels sometimes called wagon wheels that were on some ZR1's, are manufactured by SLP in correct offset for C3's, They are sold in either silver powdercoat finish or chrome. Probably does not solve the issue of wanting wider tires on the rear to fill up your flares. Forum sponsor VBP (Vette Brakes & Products) carries a variety of wheel adaptors.

I still appreciate your additional information. The five spoke wheels you speak of, are they the ones on the early C5 cars, or the A-mold wheels on the 1994 & 1995 ZR-1s? Aren't the 18" C5 wheels 10.5" wide? That should be enough width to wrap some 315 sized tires on.
What I really need are some locals with different wheels to see what I can fit on my car without (and with if I must) adapters. I know G.M. changed the firing order for the LS series of engines, but I presume all Corvettes still have the same 5 x 4.75" bolt spacing?
I may end up getting different sets of wheels for different purposes. I can see myself getting four C4 275/40/17 wheels with spacers/adapters and some rock hard tires (wear rating 340+) meant for daily driving, and a set of ZR-1 sized wheels & tires with more sticky rubber: Michelin Pilot Sport, Falken Azenis, Toyo Proxes RA1 and the like, for autocrosses, track days and some rare fun street driving.
