Mine, too, (an 87) sits lower in the front, than in the back, judging by the gap between the rear tire and edge of the outer, painted, wheel well fenders, which are 3.5 inches out back and 1.75 inches up front.  (There is obviously more clearance under the body, but measuring from top to tire to the fender opening is easy to figure....)

I know it looks better to have the rake down toward the front, but a more level ride would make for a more practical ride.

Anyway, is there a way to adjust the front suspension height, so there is more clearance up front? 

I often scrape my air dam on raised or slanted side streets, drive-ways, etc., and would like to raise my front end up, if possible.  Is there an easy adjustment that doesn't require a new suspension component or different springs, shocks, or bars?
