I need to space my day old 18/9.5 chrome Z06's.The back spacing is 65mm and I like the way the 56mm look.Did anybody ever space their rims out with some decent amout of horsepower?Please let me know were I can get some of these.Thanks....John

 

9mm is only like .350 inches, hardly noticable

 

Check out this thread. That guy is using a 4th gen rear with 18x9.5" C5 wheels. He is also using 5/16" "slip-on" style spacers. You could use that size or a 3/8" to move the rim out towards the body a little bit. I've seen them sold at Pepboys and autozone before.
