Dude, I am sooo confused. No one seems to help. The people that make the wheel adapters can;t answer specific questions... I am tremendously pissed off...
Either I put factory wheels on  the car, or go with some crappy torq thrust II wheels and look the same as everyone else. No other wheel companies make off the shelf products for our cars, some 3-piece custom wheel companies won;t do it even if I supply the measurements. There has to be some company out there that makes an attractive looking wheel that fits today's modern looks, and not a crager ss knock off, or some modern twist upon  that traditional 5 spoke design.
THe new corvettes on the same 5 on 4.75 bolt pattern even the 2010 model does, however the backspacing of 6" and offset of +58 doesn't help either.. Are we forgotten in the dark? Shunned to one type of wheel? WTF?

If you drive a vintage car, you should talk to suppliers in the vintage car terminology.  Wheels are measured in inches wide, with inches of backspacing.  You might get better results.  But in any case please clean up your language.  I think many members who might have been tempted to help just ignored you because of your apparent attitude.

I don;t think my language was brash, I don;t really have a foul attitude. In today's world of wheels, no one uses Imperial Standards, its all metric for the fact that they  are usually all made in China or Korea. But even USWHEEL (all made in USA) use metric standards for measurement. You have to just remember the convert is 1" = 25.4MM

I'm just trying to find out if my measurements are FULLY correct in terms of finding out backspace conversion and such, are these adapters safe, and what will they look like if there has to be a
 2" to 4 " adapter?  will it stick out too far? With a rim size of 8.5" 8.5" + 2" is 10.5" and
8.5" + 4" = 12.5" Thats kinda high, especially if you have stock trailing arms, or am I just over thinking this?

I'm just thinking out loud but, no one but the manufacturer can speak for the quality of the spacers but as far as fit is concerned, if the wheel is 8.5" wide with a 6.5" backspace, and you mount it on a 2.5" spacer, it should still go right in the wheel well, but the tolerances were already so close that it wouldn't be a surprise if something rubbed . that's why I mention having a shop that would work with you to insure a correct fit. Other wise it's just hit and miss. I guess that's why more of us don't do the same. You see a C3 occaisionally with custom wheels, but I'd bet it it wasn't easy fitting them on there. Good luck on this project Louis, We'd sure like to know how it turns out.

Jim and Larry are correct!!!  I live in Wisconsin, have lived in Texas.  I enjoy football but I do not think that you mean that "WTF" stands for "Where's the Football".

I'd suggest doing a Search in this forum with the keywords wheel, offset.  There should be several threads that discuss wheel measurements and fitment.

That being said the wheels I put on "The Toy" required a 4 inch custom spacer.  The wheels and spacers were found on eBay.  If you look closely in this shot you can see the spacer between the spokes.

Well said Larry. Louis, abbreviatin cusswords has the same effect on folks as writin em out. Not much of anyone takes to that stuff here.

I have a great wheel guy out of NC that I got my wheels from. I try to find his # tonight and I'll PM it to you. He knows C3s very well. BTW, all you measurements might be spot on and everything height and width wise may check out, but check you caliper clearance. Aftermarket wheels are notorious for caliper clipping on C3s...

Paul

Even my  TT II's that were made with the proper offset clipped my calipers. It looks like your are trying to push the envelope with the tire size. Our fiberglass bodies vary a fair bit so when you are trying to push the envelope on size, you may find rubbing going on. These wheel manufacturer know that and don't want to end up with a set of wheels they can't use. When using wheel spacers you have to be real careful. Moving the wheel out will increase the bending load through the spindle and axle. This can cause your bearing to fail prematurely and or snap the spindle/axle. So if you are going to go this route, do periodic inspections for cracks. How do I know that? Well I am an Engineering Manager and run new product development teams for a mobile equipment manufacturer. We pay very close attention to wheel offsets and loads. When there is too much things break. suncountry2010-02-12 13:28:34

I'm cornfused Louis..... am I wrong or dent you buy wheels and tires way back when? I wuz a-thinkin ya showed pics of em just ta tease us some. Which by the way.... ya seem ta be purty gud at..... Tuxblacray2010-02-13 23:50:55

Carr's Corvettes here in the Dallas/Ft Worth area made his own spacers and mounted Z06 wheels on a '71.  You might contact him.  http://www.carrscorvettesandcustoms.com/

As far as his abbreviated cuss words, no biggie.  The grammar on this site is atrocious.

Hi Louis: Check with Intro Wheels. I bought a set of 18 inch billet wheels from them in 2004. They were made for my car, 1968 Coupe. The front tires are 245/40ZR18 Nitto NT-555 and the rears are 275/40ZR18. The wheels are 18x9 upfront and 18x10 in the rear. They are their Pentia wheels, which are 5 spokes with nice deep dishes. Since they were manufactured for my car I do not have spacers. They are inherent in the wheels, they do not protrude and never had any rubbing of any kind. The owner know very well the old Vettes. You can find them at www.introwheels.com. If you see a dark blue 1968 in there, that is mine, which is currently being restored. Hope this helps. Joaquin
