I was wondering what the correct ride height is for a 68. I had some say at cruise nights this past summer that my car looked a bit high (I tend to agree but don't know what's correct). I currently have 215/70R15's on her, which puts the outer diameter of each tire at 26.8". As you can see in my signature pic, the back (to me) looks a bit high.

Here's another pic from the side:



What would cause that besides incorrect coil springs? How about incorrect shocks?
