I am not looking for coilovers but would like springs that offer the biggest drop for my '04 MCS. Can someone please refer me to which ones to get and a link to an online retailer? Thanks.

 

The lowest you can go with a lowering spring is about 1.5", and doing so eliminates all compression travel [read: harsh ride]. Consider V-Maxx coilovers to lower more than that and not knock out your teeth...and they're not expensive and don't suck.
