From what I've read, the coils are pretty much a rebranded KW, only that it's 2 way adjustable, not 3. I have yet to adjust the stiffness on mine (I think it's set to the softest). Mine is also lowered about 5mm all around. But for the peace of mind, it's a nice upgrade to do, and you don't have to worry about warranty being voided. If you don't care about warranty, then I would invest in a nice set of KW or Ohlins depending on your needs.
