Poison

I have just got a used set of front - HKS Hyper D - coil overs, and I can't seem to find any data on them other than in Japanese Does anyone have anything on these? Or know where I can look please? I keep reading that they are 16 way adjustable.... OK... so I immediatley fail HKS Hyper D 101 as the only adjustments I can see are the Nitrogen Valve (any idea what pressure range??? and how to decide) and of course the spring height... So anything would be great. Cheers
