Got a question for all you lowered burb guys?

[Heavy Evy]

I found a set of 6inch rear drop coil springs for my burb the only problem is there from a pick up. I know the burb coils are a bit more stout. These are for a great price and don't really want to miss the chance since im no rich fool. I'm just worried that rear will lower too much and the axle will hit the frame or other problems. I have heard of helper bags(?) and other parts to keep the coil from lowering too much. Anybody ever run pick up coils and not have a problem?

I used 2" drop pickup coils from ECE and it dropped my burb about 3 inches. I was told that pickup coils will drop an extra inch in a burb.

I hope that helps.
