I just shipped my forks and shock to Race Tech. They are going to do a complete R&D of both to see if they can use their typically excellent gold valve products for the stock items (no R&D labor cost to me since it is a new application). I hope they can, since I want a real damping performance improvement without spending $2K on a new shock and complete cartridge replacement. If they can develop the products, they normally offer them for sale to everyone, though some applications will require them to do the labor depending on the modifications needed. It will probably take about a month before they are done, and I'll post an update then. I shouldn't miss riding any since I woke up this morning to a foot of snow and 10deg temp.
