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.

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.
