Default Raise the rear!!

Hello,
1992 auto 92000 miles regular coupe. I am interested in raising the rear of my car but only an inch or 2. I have read up on lowering the car with lowering bolts, but conversely, can you raise the back of the car in a similar way? What are the best options to do this?

Thank you in advance,

Kevin

Short answer: Yes.

I found this picture with google.
The chassie is lifted by the composite spring and it is hanging in one bolt at each end.

A shorter bolt lift the spring and chassie.
A longer bolt lowers.

You can more or less use any bolt of the correct diameter, but you need to drill a hole to secure the nut with a cotter pin.

At the center spring mount there is usually some spacers you can move above or below the spring to change ride height my the same amount.

Yes it is possible but not sure why one would want to do that to a C 4.

I had to raise my driver side by tightening the bolt to get both sides of the car level (driver sat 3/4" lower than passenger side), pretty easy.
