The instructions are on the KB-Silvolite site if you go into the piston part number detail. There's a link for special clearance info, then another link for installation guides. Might be a faster way but that's how I found it. Where I would set it depends on what it's going to be doing and who's doing it. For no power adders and a heavy foot I'd go .005. Loose tends to be faster at the track but will wear the rings out faster.
