I was referring to Swift lowering springs (for stock shocks) in comparison to my current ride height.
I believe the Swift spring option for these coilovers allow you to spec the exact spring rate that you want. Ride height is completely independent from the spring options as it set up on shock itself.
I will have to ask Annex what are the advantages of going to Swift springs. I'm sure they're slightly smoother and/or have more consistent quality and performance. The standard springs that these come with are good enough to be honest.

I don't quite understand the obsession with Swift springs unless they're just generally high quality (really only meaning consistent measurements) or they wind their springs to have fewer coils so they weigh a few ounces less. Springs are not a new technology so I have a tendency to think Swift just got into some niche of the market where people somehow think Swift springs make a difference over Eibach or other name brands that have been in the industry for a very long time.
