JohnRR said: Hi All,
I'm new to this forum and have taken an interest in this thread. The discussion about backspacing and negative offset doesn't seem correct to me. If an 8" wheel has a 4" BS then it has a Zero offset. So if an 8" wheel has a 3.75 BS then it would have a negative 0.25 offset. That would be -6.35mm offset not -19mm. Am I missing something here?
Also, if the wheel has a 3.75 BS, a 1/4" spacer won't fix this. It would make the BS 3.5".
I'm trying to understand all this wheel terminology because I'm installing a set of C5 wheels on my '73.
Thanks everybody,
John
John you are 100% correct. The 1/4" spacer would change things to the 3.5 inch mark and bring the wheel outward.

Wheel update. With the information from you guys I decided to order one wheel for a test fit. It came in on Saturday evening and I tested it on front and back... IT FITS. I placed an order for the other 3 on Saturday night with Summit. Now Ive just got to wait for them to arrive and get my tires switched to the new wheels. Ill post some pics when they are on.

They actually are C4/Camaro A-Mold look-a-likes. Here's a better peek at them: https://www.c3vr.com/member_pages/401_500/419/TheToyAtBG_lg.JPG

Narley retro look! I had a set of those on the front of my 69 cuda fastback Formula S They were Keystones.

Lookin' good, Chip.
I like the look of those retro-style wheels on a C3. Too bad you didn't have them on when we were in Charleston. Would have been great to see them in person.
