I just installed my OEM z06 rear quarters on my z51 coupe. I already have 18x11 CCW c14's (made to fit the coupe)
What thickness spacers do I need to make the wheels as flush as possible without rubbing? I have 295/35/18 KDW tires.
Sorry I don't know the offsets of the CCW's, they're not stamped on the inside of the wheels.

If my car had coilovers I'd just pull the coilover and compress the suspension and watch how much the wheel moves inward as the suspension compresses but its kind of a pain in the *** to do that with the leaf spring setup. So measuring from the edge of the wheel to the inner fender is kind of useless....

Basically I want the max width (aka flushness) possible. But not really into the whole VW "poke" thing. At the same time I hate the way the wheels look when they are sunken in....

soo is 2" acceptable?

I have a bunch of spacers in my garage. Stop by and we can see how many you need.

I have Ace slicks with a 1.5 inch adapters for a few more days until I put on my black gs wheels. Ace slicks have a very aggresive offset like the ccw's. Make sure that you get hub centric adapters.These are a few years old, but you can see where the rim come out to.

hmmm 1.25 was enough for you then? IDK if that will be enough on my wheels. to me the offset doesn't look that aggressive on stock fenders, the hub of the rear wheel doesn't go anywhere near as deep as the front 18x10 wheel...

I wish CCW made it easy and stamped the damn wheels with the offsets so I could just calculate what I need then be done with it!

Just call them and ask what the wheel specs are.

That was a useless phone call. Chip told me they custom make all their wheels and there is no standard so I would have to measure them myself.

It's cool I'll go to my friend at Proformance Industries and they will measure for me and get me the spacers I need. I'll post results for future reference. They have an awesome shop where they work on a ton of Exotics and custom make their own wheels in house!!

No one I spoke to on the phone about the CCW's were any help, sooo I went ahead and ordered 1.75" spacers for the rear. I figure if they sat flush under the OEM base quarters then if offset by the same amount the Z06 wheels are offset from a base coupe, the CCW's should sit flush under the Z quarters. +45 wider (aka same amount wider the Z wheels are than the base) = 1.75" (close enough)

I'll post up how they work when I get them! They are the billet 6061 aluminum hubcentric adapters.
