Put Eibach pro kit springs on my car (2001 mustang). The front dropped like it's supposed to but the back didn't. It's sitting noticably higher. I took it to 3 different shops and they all said it's the springs. It doesnt look like Eibach or the place I got them from is going to do anything for me, so my question is could i cut the dead coil on the rear springs or remove the spring isolators to get another quarter to half inch drop. Will it do any damage to the car? Thanks in advance for any help.
