Fd rear suspension question
 

Hi all and thanks in advance. I have an issue with the rear ride height of my car I changed the shocks to tokico ill and used the factory springs, I don't know if it was lowered after I put them in. I don't think it was, but it is really low in the rear as of now. The car still handles great but the look of the rear sitting lower than the front is driving me crazy! So my question is are the springs weak in the back or should I be looking somewhere else. Just wanted to know if anybody else has had this problem before. I have been searching and have not came up with a situation like mine. Thanks again for any help.
