Eibach rear springs

[hurricane]

Well , here is my problem, I installed the Eiabach lowering spring kit on my 87 MC SS on my first drive my *ss end is bottoming out every bump I hit, what kind of springs are you guy's using that have lowered your cars ?
That was the first time and will be the last time I buy anything Eiabach, not impressed for the $$$.
