Shawn, I was under the impression that the spring was at the center, transversely mounted? I certainly don't see any coils under there! I dunno, never actually been under a vette, but I'm told it's pretty high-tech and creative use of leaf springs.
EDIT: I did a little research and found more info. It's not solid axle, it is, indeed, IRS with transversely mounted leaf springs. Here's a better pic of an older model using the same concept: http://images.google.com/imgres?imgu...lr%3D%26sa%3DG
EDIT 2: I did some more research and found a pic of the C6 leaf springs. http://orasoft.com/Auto_Show_2005/Re...Suspension.JPG This is the passenger side, from the rear. Look under the lower A-arm and you can see a piece of it. Way cool use of it!!!
