Wheel help

I have searched the forum and I can not figure out how backspacing and offsets work. The wheels I would like are Coys C-5's. Here is a link to the page.http://www.coyswheel.com/coys.html I am wanting to keep 17 inch wheels on my 95 Non ZR1 and was wondering if any of these would fit if so what backspacing do I need.
Thanks in advance.

Wheel offset is the distance between the wheel mounting face and the centerline of the rim. Backspacing is the distance from the wheel mounting face and the inside edge of the wheel where the tire contacts the inside lip.

Stock 88 and later 17" wheels with the stock 9.5" width have a 56mm offset and backspace is about 7.4 inches. Pre-88 factory wheels that were 9.5" wide had a 38mm offset and a 6 7/8" backspace.

Unless things have recently changed, Coy's have nothing for a C4 Vette
Call they to make sure, but they don't custom backspace either

I guess I knew how offset and backspacing worked after all, I was just hoping I was wrong. TT's were my original choice till I saw the Coys. I just like the smooth pan of the Coys. Anyone know of any other similar wheels I may be over looking. If not it will be back to the TT's

What size are your TT's

Thanks for all the help everybody.

Isn't there anyone out there who knows if there is away to get these wheels on and make them look and perform right. Surly someone has to have a better understanding of all this then I do. Any help will be appreciated.
