non-lowering springs+air cylinders

[mbdblue]

basically, Im looking for new suspension for my rear end. I wanted to bag it by next year, but it doesnt look like thats going to happen since cash is gonna be tight and Ill probably only be able to squeeze it out for the system and a rear end upgrade.

problem is, they only have air cylinders for my car available, and I heard bad things about how rough they make the ride (I dont really want shit vibrating off the car when Im not turning up the volume). the other problem is, I can't find springs that don't lower the car. I can guarantee its gonna be low enough with the system in. so does anyone know of heavier duty springs that arent stock that won't lower the car? the closest thing Ive found is Tein H-Techs which will only lower it 0.7 in the back. not too bad, but anyone know of others?

also, anyone running on cylinders who would vouch for them? Plus theres the cost of air lines, cylinder, compressors, stuff like that. Can I just fill them up manually and leave them like that? that way I can have the capability of adding switches and shit later. any info would be cool

edit: Im also thinking out loud through this whole thing so please keep that in mind

Do you have progressive rate springs in the back?

You could figure out the stock spring rate and height and go on Summit and look for a similar height but stiffer spring...

I am running cylinders on my car and they work fine the only time its rough is when they are fully aired up or fully out of air other than that they work great. you are just going to want to slow down the drop cuz with the extra 5-600 pounds in the trunk you will mess them up i learned the hard way =)
