CCW owners inside please!!! im trying to mount my 18x11 rear wheels and it keeps hitting the inner fender well. I know i need a spacer but dont know which one to get. I thought these would just mount up but i guess not. Anyone know what i can do to get these on.
thanks
jay

Installing them while the rear end is hanging by the shocks will probably present some problems...while under full droop, the inside lips of my 18x11 CCWs would contact the bump stops on both sides. It clears them with the rear end loaded though.
For mine, since they tuck so far in, I went ahead and trimmed off the bump stops, and instead run bumpstops on the shocks themselves. An adjustable panhard rod is a must, and had already been installed on my car prior to the install.
If you opted for the Corvette backspacing (which they offered to me once upon a time for resale potential), you would have to use a spacer. Otherwise, no spacer should be necessary, although I found that some grinding on the bump stops and a 1/4" spacer was a temporary fix until I just took the bumpstops entirely off.

More info on how I did the bump stops in the rear?
Step-by-step:
1. Grab a grinder
2. Wear safety glasses...this is gonna get messy
3. Remove bump stops (rubber portion bolted on)
4. Turn on grinder
5. Grind off mounting tabs
6. Throw away bump stops, because unless you plan on welding on some new mounting tabs, they are now useless
7. Remove shocks
8. Install (insert favorite brand here) bump stops on the rear shocks
9. Reinstall shocks
10. Enjoy more room to tuck your wheels in
I used Daystar EVS red bump stops, but probably would have done the black ones with how soft the red ones are (although I haven't had a chance to test them on the road yet due to other issues).
Do this at your own risk...I'm not sure why GM decided to incorporate the bump stops so that they would contact the axle tubes instead of on the shocks themselves just like the front bump stops, but I wanted the extra room since I drive my car hard around corners. Maybe the bump stops on the shocks aren't as effective at stopping the shocks from overtraveling, but the stock SS bumpstops in the back were just too damn jarring for me, and would upset the car.

My wheels only contacted the bumpstops themselves...the tires themselves contacted a couple places on the inner fenders, but never the rims.
You could just have the wrong offset wheels, although I'm not sure what kinda spacer would have needed to be used if they sent you wheels made to Corvette dimensions.

Steve already said what I would have said. I have no issues with mine, 18x10 and 18x11 and don't need spacers. One issue I have not seen addressed here is what size tire are you trying to run? I run 295s in the rear and I believe Steve does as well. I don't think 315s would have fit without some pretty good modifications.

I had no problem with fit on mine. I didn't have to to bfh mod at all to the inner wheel well. I had to roll the fenders for my own piece of mine but that is not your issue. Did you have them cut for an fbody or vette spec? Vette spec you need spacers, with an fbody cut they should go on no problem.

I got it guys. i talked to john @ ccw and he said i needed to jack up the car with by the pumpkin and they should go on. What i had done was jacked up one side which cause the rear to go the opposide direction. So now theyre on and they look damn good.

I have no issues with mine. I had ZR1's 17x9.5 front and 17x11 rears with Sumitomo 315's in the rear no isues. I now have 18x10 and 18x11 CCW's with 275/35/18 + 295/35/18 Vredestein tires. I have no issues the Verdestein tires and the CCW's. I will also state night and day difference bewteen the two combos.
