what are the big differences, are the tein's twin tube and the jic's single? what about ride quality? also does anyone have the EDFC and how well does it work? this is going on an FC

 

Let me know how your suspension setup feels. I was thinking of going coilovers too with camber plates.

 

I would take the Tein Flex w/ EDFC over the JIC's. The ability to change your damper settings from the driver seat is pretty cool.

 

Flex, twin tube
FLTA2, monotube

Those are your primary differences. The flex is a good suspension setup as well. But more designed for the street.

On the street I never would need to change my settings. One should have a couple of "presets" and leave it alone. IMO, that's all.
