I was just talking to Matt (SK's son) who said that is way too stiff Luke. They recommend about 5 or 6 on the front and 4 or 5 on the rear with heavy sway bars to compensate........unless your vehicle is mainly used for track.
Spoke to Polyair Suspension in Sydney today, who are very knowledgeable about damping rates, and they said that even though Jap stuff have either 16 or 32 steps of adjustment, the difference between the softest setting and the hardest is not as great as a European shocker with only 9 settings..........go figure?!
