Saw a picture of a 450SLC at http://www.dhc.net/~pmhack/mercedes/450slc76.htm and it appears that the back end is raised up a little bit. I kind of like how it looks.

How do you do that? And does it affect the performance adversely?

Thanks,
Ray

Suspensions are generally at their best when the frame is parallel to the road surface. By raising the rear of the vehicle, all the work Mercedes engineers put into the geometry of the front suspension goes out the window. Expect odd handling and increased front suspension wear (parts that were designed to move backwards slightly to absorb road shock are now forced to work in a more vertical plane than intended).
