I saw these a while back and was wondering if anyone was using them. I am going to be switching springs on my Koni yellows and thought if there was enough pros I would consider getting them. Any input would be great, thanks.

 

what does it do?

 

I think it allows you to use a spring from a coilover. Sorta like a coilover kit such as ground control or comptech. I am not sure you could use it with a regular drop spring, but I could be wrong.
