I installed the Gold valve system with the emulator included. I don't know much about the other kit sorry. I installed .95 Racetech front springs by there recommendations. I am sure you can use other springs with the Racetech valves they should work I just didn't try it. Good LuckGeneral question, but not technical issue. Notice two different "kits" available. An "emulator fork kit", and just "valve fork kit" ? Then do the springs have to be same brand, or do these work well with other brand springs?
