They're not damping-adjustable, which is a limitation. But I'm curious about them too, as I need higher spring rates and more damping, as well as more travel (I hit the bumpstops when loaded on my current setup, as Reno guys can attest
)
I'm waiting on some answers on spring size, becuase if I can use ERS stuff, it's a no-brainer for me right now.
I could probably sell my GC setup to someone who doesn't want to go as low, for a good chunk of that price.....
