I installed lowering springs on my car. Now the ride is really harsh/bouncy. Why?
If you didn't change the struts along with the springs, you're going to notice why suspensions are all specially tuned at the factory. The stock struts are not meant to dampen the kind of shock they are now receiving due to the stiffer springs. They just can't handle the extra stresses, so they bottom out, don't rebound fast enough, and just under perform. You can remedy the situation by purchasing new struts meant for lowered applications.
