2008 Altima 2.5S Sedan suspension.......

[DanDB64]

Hello all who are 500x more knowledgeable than myself. I own a 2008 Altima 2.5S Sedan, and I am looking around, searching, etc. for suspension upgrades for my sedan. From what I am seeing, there is NO coilover setup for the 2.5S sedans, only the 3.5SE. Is the Eibach Pro Kit or the H&R coils the only way to lower this thing? By no means will this thing be a race car, but there is something about putting lowering springs over my stock shocks that doesn't sit right with me. I don't see anything along the lines of adjustable shocks either, which is no good. Can anybody give me any insight on this? I would love coilovers, but that's looking to not be an option.
